Description
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 1/2×28 — 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:
- Caliber: 9mm Luger
- Fits: SIG Sauer P365XL (factory drop-in)
- Thread pitch: 1/2×28 (standard 9mm suppressor / comp thread)
- Finish: Black nitride
- Match-grade machining
- Includes thread protector
- Made in USA by Brownells
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.
