  1. D

    Quality products and service like always.

  2. Sean

    Parts arrived fast! Everything fit as it should and working well in my P80.

  3. Patrick Llanes

    This trigger kit is complete and Glock OEM. What else can you ask for? Completed my Polymer 80 build easily with this complete kit.

  4. Adrian

    When I recieved my G19 frame parts kit I was disappointed that it was missing the trigger spring. I went on the Rockey Brass web site and let them know it was missing. The next morning I had two emails from them apologizing for the missing spring and another saying the trigger spring was shipped. Now have all my parts and am finishing my Polymer80 PF940C. Great customer service and very responsive. I will definitely buy from Rockey Brass again.

  5. Brian McArthur

    I’ve already purchased other sizes and they all work great. Just as good as OEM or better.

  6. Billy Kidd

    As always rockey brass comes through… Best product best price

  7. Tom

    The LPK went in with no problems, I just put 100 rounds thought my 43 and it ran great.

  8. Jeremy Robinson

    OEM part kit!!!! Great product

  9. James

    These are “base” model, 3rd gen parts and function as they should. I’ve been involved with eight or nine P80 builds over the last seven months and they all use this lower parts kit and they all run well. I would recommend upgrading the gen 3 ejector to a gen 5 ejector while you’re building but that upgrade is easy to make later on if you decide to wait.

  10. Jeffrey Hackney

    As described

  11. David Conley

    I got my item in a timely manner. I’m waiting on other items to use this one, but everything seem to be in working ordered. Thank you.

  12. Al Clements

    Everything fit and worked perfectly, great quality parts.

  13. Michael

    Great experience Fast shippingGreat parts

  14. Jimmy Gorman

    Exactly what they advertised and was shipped almost right away, will definitely be purchasing products in the future

  15. Teel

    Great LPK, fast shipping as usual.

  16. N Staten

    Needed OEM lower parts kit for Polymer 80 that I purchased from RB back in December. I added the lower to a MechTech systems PCU upper which required OEM trigger. I have not fired the completed unit of badassery, however I believe it will be ok. The trigger seems to have a slight grainy operation that I’m hoping will go away after some discharged rounds.

  17. Shardan Radmanesh

    High quality parts and fast delivery. Couldn’t ask for anything else.

  18. Van

    Not a bad kit, I like it

  19. d

    Nice parts. They fit. No issues

  20. Warren

    Worked great. Paired up perfect with my polymer80 build.

  21. Frank

    These are the best, hard to find. Rockey brass is the best

  22. Jeffrey Maxham

    Honestly it’s a decent kit however I just wish the finish on the pins were different. At least on the set that I received, the locking block pin finish chipped away so much that now it doesn’t fit in the holes properly and is loose.

  23. Chuck Sanders

    Good product. Fits perfect with my P80 PF940CV1 frame.

  24. Cyph

    Searched MANY shops online for this parts kit, everywhere being sold out. Needed two G19 kits, and one G17 kit for two PF940C and one PF940CL polymer80 frames. Holy mother did I get lucky. I purchased those exact needs and it was sold out here after. Purchased 3 gen 4 trigger housings on Brownells for the ejectors (as per MarineGunBuilder’s suggestion). Glad this kit is OEM. Disappointed that the price is probably $30 more than it should be, but I guess this is why I was able to find it in stock here. Considering the circumstances, I am very pleased. The parts look good, and everything was in order. Thanks again.

  25. Mark

    All parts seem to be made to spec and fit well

  26. Andrew

    They had me at Good price, in stock and quick shipping. everything working like a charm was a huge bonus. 5/5 stars

  27. Jared Quintanilla

    Shipping was a bit long but got all my items I wanted. My slide was bent and still waiting to hear back from customer service. No response after 3 emails

  28. Arnold

    This is not the first Glock frame kit that I’ve purchased from Rockeybrass. I’m very satisfied with the price abc quality of the kit. Thank you again Rockeybrass.

  29. Nemein Wulf

    Ordered on 10/2 morning and get it on 10/5. They ship using USPS priority 2 day. They have the frame part kit while every other dealer seems to be back ordered. I got the frame also and most other place is also out of stock, Good job.

  30. RedActual

    Zero flaws, zero issues, very fast shipping. If there’s a good deal you see on rockeybrass, I suggest you buy it asap…these kits were back in stock and sold out in a matter of hours Ultimately would recommend this product and the seller without any reservation.

  31. Douglas

    Worked as intended and it is a good price. Good quality.

  32. Anthony Hernandez

    Great kit! Comes with everything to complete the job. Fits nicely. Great product. Fast shipping. Great price. This kit wont let you down.

  33. Tyler Case

    This was a complete waste of money. I never received any of these items in my kit and it seems like every time I try to contact someone I completely get blown off and ignored…..

  34. David

    Ive been searching weeks maybe months now for a LPK for my g26 build , saw that rockey brass had just what I needed and in STOCK !! I got my parts within 3 days amazing fast shipping highly recommend this product and entire site in general!

  35. Ron P.

    Parts as described. Item arrived just in time for Labor Day weekend, (fast delivery) thank you so much. Lower parts works flawlessly.

  36. Oscar

    Great customer service, great products, great prices and overall just a great experience with Rocky Brass! Thank You.

    Slides right in with no problem at all. I love it. And fast delivery to.

  38. Kyler Toan

    Great parts, and shipping is quick everytime Ive ordered. Even during the pandemic madness they had my parts shipped very quickly

  39. Harry

    I’ve made several purchases from these guys and every one has been great. Rocky Brass is one of my favorite places. Thanks for all the hard work and dedication!

  40. Gregory Robbins

    Order was just what I needed at a fair price and fast shipping. Thanks Rockeybrass!

  41. john law

    good price, amazing fast shipping, good part

  42. Jonathan

    Fit great no problems

  43. Ron

    Decent product especially for the money. Seems good quality.

  44. Dave

    Great fit and finish, all parts function flawlessly. Highly reccomended!

  45. Kevin

    Polished trigger arm bar and extractor. Swapped connector for a Zev. Fits and functions beautifully.

  46. David Miller

    Just what I needed, a complete parts kit and in stock!! Rockey Brass shipped out fast and I got my order in no time at all. First experience ordering from them and all was perfect, will definitely consider them next time.

  47. Jerry Hayes

    Definitely OEM. NO frills, No extras, No improvements… If building a Poly80, stay away from Glock OEM kits…

  48. Vincent Parbo

    Works perfect! Fast shipping! Thank you!

  49. Rich rich

    Great products for a decent price considering the times were in at the moment. Everything is and work as it supposed dont think ill be running into any problems all around good products. Will be buying more. Just hoping they come down in price a little so i can stock up before our 2A is in the history books

  50. garnett hamlin

    Great price, fast shipping but trigger housing had 336 ejector. Would rather have 274 ejector.

  51. Grayson

    The tried and true Glock systems are genius and extremely reliable, but their machining is a bit lackluster, so some buffing and polishing is much recommended for a couple of the parts, but other than that these are great. I installed them in my Polymer80 PF940CL with ease, and they function perfectly, every time. Seller included everything that is listed in the description in a nice little labeled package, shipping was fast, and I would definitely recommend to anyone who is looking to build a Glock, P80, or replace parts in your Glock.

  52. brandon

    fast and easy shipping, everything fit perfectly

  53. Sam Sade

    These parts definitely need to be touched up before install. You might need to fit them to optimize function when installing in a Polymer 80. Mine didn�t come with a slide lock spring, luckily I had a spare. Make sure every part is present. Fast shipping, seems to be a great dealer.

  54. Kevin

    This LPK is super easy to use and install. A great buy when ordering a P80 frame. I would recommend.

  55. Boca

    Front rails are poorly cast. The edges of rail are rough and bumpy and the top has all kinds of seams and wrinkles in it. This has resulted in poor function and rough fit

  56. Travis Mathis

    8 figured this would be a great buy right, well i was wrong. Almost all of the metal parts need to be polished or you’re getting a very sticky trigger and upon furhter inspection the slide release spring was bent all to hell. My trigger was not resetting because of a bur that is known yet is not fixed so again, i had to file and work on parts that should be fine from the factory, not to mention where the actual slide sits on the rear piece was bent to hell. Not impressed with the parts or quality nor with rockybrass’s customer support and because of this i will never buy from them again and urge you not to as well.

  57. Ben

    Missing parts.. can I say much else?

  58. Cameron Docksteader

    Great price for an OEM large frame glock parts kit. No complaints here.

  59. matthew yantzer

    Great deal on a lower parts kit for my 940CL build. Parts were the same as other EOM parts kits I have ordered from Brownelles. Shipped quickly. I would recommend you buy this kit if you are looking for OEM parts.

  60. Tom J

    Lower parts kit was reasonably priced, fits perfectly and requested a smooth trigger when ordering and received it. Couldn�t be happier. Thanks!

  61. Brian Hinds

    Good fit in the new Polymer 80 SS. Easy install and good function

  62. J

    After some price comparison I found these were the best quality parts for the money I found it slightly cheaper elsewhere but rocky has much better quality for small price point

  63. Robert Clemmons

    more than happy with the quality of the product and the service I receive from Rocky Brass will do business again.

  64. Daniel

    Delivered early, excellent quality.

  65. Henry Newman

    Great product! Got 3 of them and received the package in a few days. They went smoothly into so P80s I have been working on! Would recommend

  66. Rob Schaeffer

    High quality parts kit. Had zero issues with any of the components. Will purchase from Rocky Brass again.

  67. Bradley Houser

    All the parts went in real easy and work really well with my Polymer 80. It’s not custom high performance parts but they’re great stock parts and do the job. This is my first handgun build I’ve done plenty of rifles but I like it that was very easy went together great definitely looking forward to do another

  68. Beau

    Cannot say enough abt RB and the products they sell! I will be installing my lpk shortly, from what I can tell they are quality parts and perform as they should. Again super fast shipping!

  69. John D Bush

    Nice kit would be better if it use the extended slide stop release and extended slide lock release lever, but the kit was a good price so I went with it and installed it. I did get the extended parts from Ebay once I was sure the 80 percent lower work was good.

  70. Stephen Sears

    I’ve been having a problem with my trigger not resetting sometimes and when I push the trigger forward a round goes off. I checked my cruciform-striker relation and it seems I’m not getting enough as Glock says you need 75-100% contact. I’m not sure if that is a cruciform issue or a striker issue. Swap the trigger mechanism and striker out with a oem Glock 22 And it works just fine. Over all quality I’d say it’s pretty good. Just wanted to put this out there in case somebody else ran also has the same issue

  71. Glock Rookie

    Have used these in a couple builds now, good so far. Good spare parts, OEM replacement or 80% build. I’m told polishing the contact areas and a connector upgrade can make a big difference for just a few dollars, about to find out.

  72. Dan Williams

    Great fit, very little cleanup on plastics, and a little polishing in a few places and it runs like butter in the warm sun. Will definitely buy it again.

  73. Steven

    Lower parts kit fits good and fast shipping

  74. Derek Seifrit

    Exactly what you’d expect with OEM Glock parts. Bought as part of a P80 build, and everything fit nicely. But as with my review of the P80 frame kit, the biggest surprise was that my package arrived in 2 days! Fantastic shipping time and great customer service!

  75. Bob C.

    This is the parts kit that I purchased along with the Polymer80 frame. Everything fit perfectly and it functions exactly as it should. I got free shipping on this item because I ordered it along with the Polymer80 kit.

  76. John

    Perfect fit. Shipped super fast considering I ordered cyber monday. It would be the tits if it came with an extended slide release tho.

  77. Mikkel

    I like this kit. It was easy to install, and works well. I haven’t fired a lot of rounds through this build yet, but it has worked well when dry firing, as well as with the limited number of rounds fired.

  78. Reuben Cabrera

    Received the items and they worked great in my Polymer80 G17 frame. They fit perfectly without making any modification.

  79. Matthew

    Excellent quality, excellent fit, works perfect. Will order many more LPK’s from Rockey Brass

  80. Tim Matson

    The trigger spring was broken with the loop broken off on one end. The loop was not in the package, so it leads me to believe it was packaged that way related to poor attention to detail and quality assurance.

  81. Charles Haptonstall

    Great price

  82. James

    Super fast shipping order was correct and complete. Will use rockybrass for all my pistol needs.

  83. Dale

    Everything went together nicely.Peeps should look up the 25 cent trigger job. Well worth doing before assembly.

  84. Rick Eckhardt

    Good lower completion kit

  85. Jeffrey Bradford

    Bought this to finish my first build. It came in very quickly and had no problems. Rockey Brass your the BEST!!

  86. Nathan Turner

    They always ship fast an free only thing is I got a bent ejector not really a big deal since i was gonna swap it out anyway

  87. Brandon

    Ordered this along with a SC Polymer80 frame, fast shipping, easy to put together. No complaints from me. Would purchase from again.

  88. Jason Thacker

    Put this lower kit in a polymers 80 and it worked great. Everything fit correctly and functioned like it should.

  89. Bill Myers

    Outstanding quality parts, service., and super fast shipping! LOVE Rocky Brass!

  94. Jared

    The parts fit with no problem at all the. Fast shipping

  95. Timothy D

    This is the first time I have built or used a Glock, all parts went in easily, trigger is not the best but it is a stock trigger.

  96. Scott

    Good parts, good price, fast shipping.

  97. Nick

    nice price.. all parts needed were there… smooth trigger shoe.. would have liked extended slide release.

  98. Geoff

    Excellent kit sold by an excellent company. I discovered a mis-match in my order and emailed the problem at 9:30 pst on a Friday night By 6am pst Saturday morning there was a response to my email with a tracking number for the replacement part. By Monday I had what I needed with a postage paid return envelope for the erroneous part. I have NEVER experienced such professional, responsive service anywhere! They have a loyal customer in me.

  99. Pat

    Bought this and it was shipped & at my door in 2 days. Everything is exactly what I ordered and I am completely satisfied with every piece of this kit and will be a return customer for life. 500 rounds through this kit with no jams,FTF,FTE or any issues

  100. Shawn M.

    These parts are as described. They probably could have used a polish job before I installed them, but I just wanted to get the pistol together. Very pleased.

  101. James

    These parts feel and work better than Glock OME parts. Great for the price!

  102. John

    I used this glock lower parts kit in my P80 compact build. It was my first time assembling a glock lower. With the help of youtube, I had it all installed. Functions 100% in my build with 120 rounds through it so far.

  103. Mark Walker

    Just as advertised! smoother trigger than my other OEMS Great product

  104. Pat

    All parts there — even an extra pin for “if needed” (now have a spare). Good quality, good price, and it all worked like it should! Great purchase!

  105. Ron Jackson

    This lower kit went in very nicely no issues works great so far. very impressed with the my new build . will build another one soon.

  106. Cody Hendershot

    Perfect fit and a perfect product. I love rocket brass cause the shipping is so fast and the customer service is the best. They always answer all my questions and they are just excuse my language but they are the sh*t. Thank you rockey brass!!!!!

  107. George Baumgart

    Quality parts easy to install and a great price . Would definitely recommend.

  108. Sheepdog25

    All you need to complete the function of Polymer80 frame at a righteousprice

  109. Chris

    I purchased this kit, it showed up on time. I installed it the same day and it went together exactly as I expected. As installed in the lower, it has functioned everytime I have pulled the trigger, no issues with the safety. Haven’t completed the entire build yet is the only reason I didn’t go to 5 stars.

  110. Benjamin

    The product arrived on time with all of its parts in excellent condition. I had heard great things about Rocky Brass and they did not disappoint. The price was perfect, products where exactly as described and I will definitely be ordering looking at Rocky brass before I try anywhere else.

  111. Mitch Pecher

    Perfect kit for your new frame, don’t hesitate!

  112. Kristopher De Ryke

    Haven’t used it yet but can’t wait fast shipping great product and price..

  113. Kevin

    G19 Gen 3 trigger and lower parts kit was awesome. Great quality.

  114. Elliot

    Promptly shipped as described, worked without any problems thank you

  115. Timothy Green

    Lower went together easily with these parts and all worked well at the range.

  116. rhcat

    Not only was the item available, but the best price I can find around. Oh and not to mention, FAST shipping. These are OEM parts so no fuss no issues. Just used it on my first build.

  117. Gary Grimes

    I’m very happy with the kit. Rockeybrass good company

  118. William Jackson

    After receiving this item i could tell it was good quality. Easily assembled and installed. Trigger seems smooth, cant wait to finish and send some downrange.

  119. Leo Gessford Jr.

    Parts kit worked flawlessly. If you need one, this is the place to get it. Fast shipping, too.

  120. Mark

    Fantastic all around looking forward to buying again!

  121. Ashton chambers

    Great products ordered and was skeptical because they didn’t have PayPal. My order was immediately logged and notifications sent through email it arrived two days later. Product is amazing have plans for another build already.

  122. Ronald SAMPLES

    This lower fit well in the polymer 80 frame

  123. Timothy Bengtson

    Great package, great price

  124. Wallace Duncan

    The best parts kit all around, favorable even over wolf, can’t beat the price or shipping on here.

  125. Guy Denham

    Polymer 80 products. The cheapest price and fastest shipping you’ll fine

  126. John Villafana

    Everything arrived faster than expected and the parts are great !

  127. James Downie

    Picked these parts up to use with a Poly 80 pf45 lower. Perfect fit, no complaints.

  128. Anonymous

    The kit was awesome and pretty self-explanatory. The bummer is the lack of aftermarket slides for the G20, there are very few options currently available.

  129. Chad Wojahn

    This came as a complete kit, everything fit perfectly, and has operated 100% sending 200+ rounds downrange, sub /super sonic. I considered upgrading but honestly it all works so well why change it.

  130. Toolslinger

    Everything assembles and fits perfect. Great for Polymer 80.

  131. richard johnson

    Good quality and fast shipping.

  132. Justin Childers

    I searched all over for a parts kit that was in stock and wouldn’t break the bank. This kit for the bill. Everything was 100% OEM and a perfect fit. Got my gun running smooth. The P80 slide parts kit had a bad extractor (not bought here) but once that was replaced the gun ran flawless. On my order under special directions I asked the Rockey Brass staff to draw their best T-REX on the shipping packaging and they did not disappoint. They drew a better T-Rex than I could, and that goes a long way in my book. Customer service specialists.

  133. Anon

    Glock fiddlybits for Glocks, exactly as advertised. Put them in, they work. No modifications necessary. Price was reasonable.

  134. Adam Chavez

    Great quality, no issues at all!

  135. Chris Bowman

    The Glock parts kit consists of Quality parts. Gaston Glock would approve. Tried the trigger function, and it is great. The parts fit in the P80 frame perfectly.

  136. Philip Anderson

    The lower frame kit drop right in. No problems.

  137. Rebecca Rowland

    I accidentally found this company on the internet and once I received my first order I was so impressed with the quality and pricing I turned around and placed a second order. Shipped fast. Great products and amazing customer service. Highly recommended.

  138. LaVell Dunn

    Good quality

  139. Nathan Green

    Kit came just as expected shipping was quick. One thing to note, almost all peices had a coating of dirty material. After I got it all cleaned up everything fit in my p80 perfect.

  140. Matt Milton

    All the parts fit perfectly without any extra modifications. Received everything 2 days after I ordered it.

  141. Ryan Dickey

    So far so good dropped right in.

  142. Mark Pease

    Parts when right into my latest P80 PF940C build. I’m very pleased with the fast shipping, reasonable price and quality of the product. Will definitely be buying more items from Rockey Brass.Mark

  143. Cody Irions

    I ordered a polymer 80 along with this OEM lower parts kit. This was the best deal I could find and it shipped to me fast. After milling the p80 the OEM lower parts kit went together without any problems, works great.

  144. Charles Le Normand Jr.

    Worked good for me.

  145. Victor Hernandez

    Great parts there basicly factory

  146. Hinekene Keomany

    Parts came in a few days after ordered. Installed with no problem. Perfect parts makes a perfect gun.

  147. Skip Boyer

    I’d change. Trigger was grooved. I would have liked an option for a smooth face.As far as functionality goes, they went right in, no fussing or modifying and, they worked from “jump”.Great price, great components, great company to work with. Rockeybrass is my go to supplier for all of my 80% handgun parts.

  148. David Ricchio

    Great delivery, quality is excellent.

  149. Agapito

    Have not installed this kit yet. However, the service and accuracy response of Rocky Brass was exemplary. I need to order more stuff to sustain this new hobby of mine and RB is the place to go. Thanks guys!


    Perfect (“Glock perfection”)as expected.

  151. Matt

    High quality fast shipping

  152. Skip

    The price was right on this lower parts kit! What made that a good thing is that it went together like it was a much more expensive one. Great product, great folks to deal with too. Customer for life!

  153. Aaron Graff

    I’ve searched the internet for my first P80 build & everywhere I checked wanted $150 for a P80 G17 lower frame build, until I found Rockey Brass dot com. I got the P80 lower AND the lower parts kit for a few bucks more. It was like buying a lower at regular price & getting the lower parts kit for three bucks! All the parts fit perfect.. Great deal!

  154. Bradley

    Great service. Great product.

  155. John M Evans

    Great price and fit perfect.

  156. Thomas Ortlieb

    As always everything I expected. This is definitely my go to store for all my needs. Delivery time is great.

  157. Pat

    Great price, only prob I had is I ordered a Glock 17 kit and it came with the serrated G19/G26 trigger. Just a heads up for everyone else. (To clarify, there are two triggers for the G19 and G17 which are interchangeable. One has a smooth face and one is serrated. We stock whichever is available at the time. ~ Rockey Brass)

  158. John Alexander

    It says that these are OEM glock parts but I’m not sure. I need to check part numbers stamped on pieces and compare with my other 17. All of the parts fit well, some black metal parts did have a powdery film on them that wiped off.

  159. Andrew P.

    I could not be happier with the item I received the sale that you had for $40 off with free two-day shipping cannot be beat anywhere two days after I receive my order I made another for the full-size model it should be here on Christmas Yves according to the tracking which will be another nice early Christmas present for me

  160. Emmanuel A.

    Everything went together well. The parts were good quality. Can’t beat the value.

  161. Joe B.

    Ordered from Rockey Brass because they had the the parts kit in stock. Price was slightly cheaper than other suppliers. Their quick service and delivery was faster. Will be buying from them again.

  162. Justin S.

    Product was as described, new condition, and I’ll factory parts. Fitment was great and easy. Shipping was incredibly fast. Overall experience was excellent. Will purchase from them again.

  163. Adison L.

    Awesome experience, everything was super easy with Rockey. Will definitely build with Rockey Brass again

  164. Paul J.

    As advertised, all parts are OEM with the same markings as a buddy’s G34. The trigger/disconnect polished up nicely. What else can I say Just like a Glock, it did exactly the job it’s supposed to do.

  165. Dylan C.

    Everything was quality parts and decently fast shipping

  166. Ted A.

    After some polishing to trigger bar and connector, fit and function was easy. Very pleased overall.

  167. rodney f.

    loved it ,simple and fun
