The Griffin Armament ATM Sig P365 Threaded Barrel with Micro Carry Compensator pairs precision machined performance with practical concealed carry reliability, delivering a tightly engineered solution for 9mm P365 pistols. Crafted from 416R pre-hardened chromium stainless steel and finished in black nitride, this barrel offers peak accuracy potential and enhanced surface hardness, resisting wear while supporting a broad duty to training ammo spectrum. All critical machining is performed in a single work holding, ensuring exact tolerances and a consistent, mate-ready interface with the slide and locking lug for optimal reliability. The bore design features broach-cut rifling for reduced stress and uniformity, a target crowned muzzle, and chambers honed and polished to provide smooth operation across a wide range of ammunition. The Micro Carry Comp adds a low signature while resisting printing, fits a wide variety of holsters without modification, and delivers noticeable recoil reduction for faster follow-up shots and improved overall control, all with a negligible impact on handling. With a 1:10 twist and an overall length of 3.75" (4" with the comp), this barrel delivers a dependable, easy-to-maintain upgrade that enhances accuracy and confidence for everyday carry.
