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.
Top quality barrel. Very accurate out of the G40. Great for top end 10mm loads.
Better than factory barrel
Great craftmenship Quick shipping
Have only shot once. Seems to be accurate. Fit and finish is perfect. After sighting in Leupold Delta Point I shot 3 rounds of Underwood 200 gr. hard cast and had lead in the barrel. Want to use these for hog hunting so won't be shooting them all the time.
