Silencerco AC5369 Threaded Barrel for Sig P365XL - Precision Performance Upgrade

The SilencerCo AC5369 is a threaded barrel for the Sig P365XL, designed for shooters who want to run a suppressor on their compact 9mm carry gun. This is a straight performance upgrade—it threads onto your P365XL in place of the factory barrel, letting you attach a suppressor with the same twist as the barrel itself. SilencerCo's reputation for precision machining and attention to detail carries through to this component: the barrel is stainless steel with a black nitride finish, giving you durability and corrosion resistance in a compact package that'll ride in your holster or nightstand without worry.

If you carry a P365XL and own or plan to own a suppressor, a threaded barrel eliminates the need for a muzzle adapter or converting a non-threaded barrel. Install it, thread on your can, and you're done. The nitride finish is proven in the field—it handles normal use, cleaning solvents, and moisture without degradation. For concealed carry, home defense, or even suppressed range work, this barrel is a no-fuss way to unlock the versatility of your pistol.

SilencerCo's AC5369 is built to tight tolerances and stress-tested before it ships. If you're familiar with their suppressors (and their track record), you know they don't cut corners on the details. This barrel meets that standard.

Frequently Asked Questions

Will this barrel work with any suppressor?

This is a threaded barrel for the Sig P365XL in 9mm. It will accept any 9mm suppressor with the matching thread pitch and mounting design. Verify your suppressor's compatibility with your threaded barrel before purchase.

Is this a direct swap for the factory P365XL barrel?

Yes, the AC5369 is designed to replace the factory barrel on the Sig P365XL. Removal and installation follow standard barrel swap procedures for the P365XL platform.

What's the benefit of a threaded barrel over an adapter?

A threaded barrel integrates the thread directly into the barrel itself, eliminating the need for a muzzle adapter. This keeps your setup cleaner, potentially more reliable, and is the permanent solution if you plan to run a suppressor regularly on this pistol.

Does the nitride finish require special maintenance?

Black nitride is a robust finish designed to handle field use and standard cleaning. Treat it like any quality barrel—clean after shooting, avoid excessive solvents that aren't designed for firearms, and inspect regularly for wear. Normal gun maintenance is all that's needed.
