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
  • Available with .578"-28 tpi threaded muzzle

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!

Brownell's Glock Barrel on a Glock 21
My 21.4 was having issues feeding 200 grain SWC handloads. The case mouth was snagging either side of the chamber mouth on the OEM Glock barrel. There is an inverted "U" shaped notch on either side of the OEM Glock barrel. The Brownell's barrel doesn't have these notches in the chamber mouth so the SWC's feed much more reliably. With the conventional rifling in the Brownell's barrel, no concerns about leading related problems in it. All in all, a worthy modification/upgrade to my 21 IMHO.
