  1. R Topp

    Drops right in, looks so clean. Ran 300 rounds thru it with no issues at all. Like all stainless very easy to clean. Fast shipping and great communication from Rockybrass

  2. Donnie

    I haven’t fired it yet, but the PF45 build with this barrel looks great. The barrel is well made and exactly as pictured. You really can’t find a G21 barrel for less money, especially when it seems to be a quality product. I would definitely recommend it.

  3. Thomas

  4. Gary Capps
