The Griffin Armament threaded barrel bundle for the SIG P365 (Griffin Armament part no. GAP365TB) is a 9mm ATM barrel with a 1/2×28 threaded muzzle, packaged with Griffin’s Micro Carry Comp. Griffin machines the barrel from 416R chromium stainless steel and finishes it in black nitride, with a honed and polished chamber and a target-crowned muzzle. The threads support an accessory or a pistol-caliber suppressor, while the included compensator targets recoil and stays low-profile for concealed carry. It drops in as a replacement for the factory P365 barrel. For a carry pistol that needs muzzle-device support without giving up reliability, this bundle is a direct route.
