Match-Grade Barrel for the Glock G21 GEN 3 BARREL BLACK .45 ACP 

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.  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.
The durability, reliability and excellent build quality of these parts will ensure years of service you can count on.
