SilencerCo AC5369 Threaded Barrel 9mm Luger 1/2x28 416R Stainless Black Nitride - Fits Sig P365XL

The SilencerCo AC5369 is a threaded replacement barrel for the Sig P365XL, precision-machined from 416R stainless steel and finished in a tough black nitride coating. Chambered in 9mm Luger, it gives P365XL owners a high-quality upgrade path for running a suppressor on their pistol.

The 1/2x28 thread pattern is the industry standard for 9mm suppressor mounting, and the 1:10 RH twist rate is well-suited to common 9mm Luger bullet weights. An included thread protector shields the muzzle threads whenever a suppressor is not mounted, letting the AC5369 serve as a direct stand-in for the factory P365XL barrel when suppressor use is not desired.

Most 9mm pistol suppressors require a booster or Nielsen device (piston) for reliable semi-auto cycling, so plan accordingly when building out a host setup. This listing is for the barrel only; the P365XL pistol frame and magazines are not included.
