Brownells match-grade threaded barrel for the SIG Sauer P365XL in 9mm Luger. A direct drop-in replacement for the factory P365XL barrel, the muzzle is cut to 1/2x28 — the standard 9mm thread pitch — so it pairs cleanly with most pistol suppressors and 9mm-class compensators. Ships with a knurled thread protector for unsuppressed carry.
Features:
Break-in: expect 50–100 rounds of standard-pressure 9mm before the muzzle device threads and the lockup fully settle. If you plan to run a suppressor or compensator, verify your host slide and recoil system are tuned for the added muzzle mass.
