The P365XL X-Series retains the micro footprint while extending performance with a 3.7-inch stainless-steel barrel and a 12+1 capacity. The slide features front and rear serrations and a matte black finish, with a direct-mount optics cut tailored to micro reflex sights.
X-Series ergonomics include a longer beavertail, an undercut trigger guard, and a flat-faced trigger for a consistent feel. The serialized, modular Fire Control Unit (FCU) uses an internal stainless-steel chassis and pairs with a textured polymer grip module.
This pistol is equipped with a SIG Sauer ROMEOZero micro optic (6 MOA). The front sight is a green-dot post, and the rear sight/plate has been removed to mount the optic directly to the slide.
