All KKM barrels are made using certified 416R gun-barrel quality stainless steel bar stock. These barrels are then heat treated and vacuum tempered to 42 RC. All of our barrels are CNC machined to obtain superior dimensional tolerances over stock. Because of our advanced proprietary button rifling process, all KKM barrels offer greater accuracy over stock barrels. Our Glock barrels come with fully supported SAAMI spec. match chambers for shooting factory or reloaded ammunition. These are drop-in barrels, no fitting or machining required.

Highly recommend
Excellent fit finish and repeated shot placement

Nicely made barrel.
I like this barrel allot. Drops in with slightly tighter lockup than factory barrel. Chamber is slightly tighter and has more support, but relieved a bit at 8 and 4 o'clock. No problem feeding lead semi wadcutters. Very smooth bore. Minimal leading and super fast cleanup. Haven't shot for groups, but as accurate If not more than the factory barrel.

what a difference. the factory glock barrel is now a fishing weight where it belongs. shame on you glock. i own 5 glocks and now my G-41 shoots the best because of KKM barrel. buy one you will love it. this practical tactical G-41 should never left glocks factory as bad as it shot. my G-19 was more accurate. thank you R.Y.G.
