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. Converts from .40 to 9mm. These are drop-in barrels, no fitting or machining required.

    KKM barrels are a very well made product. They bring more prosecution to your shooting, I also have a KKM matched barrel in 40mm. which have used for years. Glock barrel are very good for a war pistol, (that’s had Glock made them) but limits to the type of load and bullet you can use. By changing to a KKM barrel I don’t have those limits, and now can shoot both 9mm and 40mm out of my Glock 23. And the price is very fair.
