MATCH GRADE BARRELS FOR GLOCK® 20 Reviews & Ratings

MATCH GRADE BARRELS FOR GLOCK 20


Our Match-Grade Barrel for the Glock® 20 fits generations 3 abd 4 of G20 It's an excellent replacement for a shot-out factory barrel or for completing a pistol based on the G20 platform. And it's the ideal tube for a custom gun built on a Polymer80 frame with a Brownells Slide on top! Each Brownells Match-Grade Barrel for Glock® 20 is machined from hardened 416R stainless steel to precise dimensions, so it's a drop-in fit on most guns. The tight lockup helps ensure superb accuracy, too. The extra-hard Black Nitride finish resists surface wear and stops in its tracks whatever corrosion might try to challenge the stainless steel. This 10mm chambered barrel is button-rifled with standard, 1-10" right-hand, 6-groove rifling that is compatible with "practice" ammo with non-jacketed bullets.

  • Fits Glock® 20 Gen 3 & 4
  • Button-rifled 1-10" twist
  • 416R stainless steel
  • Non-reflective Black Nitride anti-corrosion finish
  • Threaded model available with 9/16-24 tpi threads


Our match barrel for Glock® 20 is available with either a Plain muzzle with an 11-degree target crown or Threaded (9/16-24 tpi) to enable installation of a compensator or sound suppressor. Both are laser-engraved with the chambering and the Glock®model it fits.

Great buy
This is just what I have been looking for, I needed an extra barrel for one of my slides. The price was great and the shipping to delivery was excellent.

Straight shooter
Well made and dropped right in my gen 4 G20. Locks up tight and shoots straighter than my Lone Wolf barrel. Shot 100 rounds of 40S&W through it only one failed to shoot. Not bad odds for a range ammo alternative. Also shot 50 rounds of 10mm ammo with and without a suppressor without any hiccups. All in all nice barrel and l would recommend it to anyone.
