You’ve got a Glock 19 on the bench and you really want a match quality barrel that will deliver accuracy you can count on with a variety of ammunition and not cost you an arm and a leg. The barrel you need is the KKM Glock 19 barrel.

KKM Glock Barrels Have the Features You Need for Accuracy

Every KKM G19 barrel is chambered to SAMMI specs and button rifled. The combination provides unbeatable accuracy with a variety of jacketed and lead projectiles. Button rifling lessens the distortion of every bullet fired creating better accuracy as bullets with less deformity fly more predictably. SAMMI spec chambers provide excellent accuracy without being finicky about ammunition type. The SAMMI Chamber provides the 9mm KKM G19 barrel with the kind of accuracy the AR enthusiasts enjoy from their beloved .223 Wylde.

KKM Uses Quality Materials and Cutting-Edge Manufacturing Processes

Every KKM Glock 19 Barrel starts with 419R certified stainless-steel barrel stock. KKM utilizes the precision machining capabilities of 4 axis CNC machining centers to produce barrels with tolerances far more specific than those of factory original barrels. KKM Glock barrels are heat treated and vacuum tempered to be strong through a long service life. That’s more added value for you whether you shoot competition, enjoy a little extra accuracy in your personal pistol or your life counts on it in tactical situations. While KKM G19 barrels are drop-in compatible with your factory Glock setup, they’re anything but standard. When you choose a KKM Glock barrel you get the same great barrel that’s won almost every accuracy based pistol competition on the globe.
