M&P Compact 40S&W (3.6″ Model)

SKU MPD0 Categories ,



All KKM barrels are made using certified 416R gun-barrel quality stainless steel bar stock. Our 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. Our advanced proprietary button rifling process allows KKM barrels to offer greater accuracy over stock barrels. Our M&P barrels come with fully supported SAAMI spec match chambers for shooting factory or reloaded ammunition as well as lead or jacketed bullets.

MAJORITY OF M&P BARRELS ARE DROP-IN FIT.  If you have an older 1.0, it is possible your barrel may need light fitting. Contact us in an email if you have questions about your specific gun/barrel.

Finish Type – Matte: A standard grey/silver finish on the chamber side and a bright polish on the round barrel towards the muzzle.
