The SilencerCo threaded barrel for the Sig P365XL in 9mm (SilencerCo part no. AC5369) adds a 1/2×28 threaded muzzle so the micro-compact Sig can run a pistol suppressor. It is made of 416R stainless steel finished in black nitride. SilencerCo notes that all pistol suppressors need a threaded barrel and built this line to the same standard as its suppressors. A thread protector comes with the barrel to cover the threads when no suppressor is attached. It is an easy upgrade for P365XL owners who carry a compact 9mm.
