MATCH GRADE BARRELS FOR GLOCK® 21

MATCH GRADE BARRELS FOR GLOCK® 21 Reviews & Ratings

Our Match-Grade Barrel for the Glock® 21 is a premium barrel machined from hardened 416R stainless steel to precise dimensions, so it delivers a tight lockup that helps ensure superb accuracy. It's a drop-in fit to most guns, too. And the extra-hard Black Nitride finish resists surface wear and stops in its tracks whatever corrosion might try to challenge the stainless steel. This .45 ACP chambered barrel is button-rifled with standard, 1-10" right-hand, 6-groove rifling that is compatible with the non-jacketed bullets of inexpensive "practice" ammo. You can get your match barrel for Glock® 21 with either a Plain muzzle or Threaded (.578"-28 tpi) to enable installation of a compensator or sound suppressor. Both have an 11-degree target crown, and each is laser engraved with the chambering and the Glock® model it fits.

  • Fits Glock® 21
  • Hardened 416R stainless steel
  • Non-reflective Black Nitride anti-corrosion finish
  • Chambered in .45 ACP
  • Button-rifled, 6-grooves, 1-16" twist

A Match-Grade Barrel for your Glock® 21 from Brownells is an excellent replacement for a shot-out factory barrel, and it's the ideal tube for a custom gun built on a Polymer80 PF45 frame!

Didn’t work for my gen 1 Glock 21
My problem with this barrel wasn’t the fit or the accuracy. It fit well and I was able to shoot several 1 1/2 inch 5 shot groups with it. The problem came when I tried to take the barrel out for cleaning. I couldn’t get the barrel out. I have never had this problem before even with another non Glock barrel. So I did finally get the barrel out and sent it back for a replacement, thinking that it was a one off problem. When I got the replacement barrel l didn’t even try to shoot with it. I just installed it and worked the slide a few times then tried to take the barrel out. Same problem. So I sent it back for a refund which was quite an exercise in itself, taking about 2 months and several phone calls to complete. I have since purchased a Lone Wolf barrel. It fits and functions well and I can get the barrel out to clean it. I only have a few rounds through this barrel so I can’t give an accuracy comparison. I really liked the accuracy of the Brownell barrel but couldn’t live with it hanging up the slide to the point it was very difficult to get apart.
