The slide features an integrated compensator with twin upward ports machined into the Spectre Comp slide, along with Spectre-style serrations and a lightening window. The slide is optic-ready and includes a cover plate, with the rear sight set in a dovetail behind the optics plate.
The 3.1 in non-threaded barrel wears a TiN (gold) coating, matched by a TiN-coated, flat-faced X-Series trigger. The pistol uses a striker-fired, locked-breech, short-recoil operating system.
Factory X-RAY3 day/night sights provide a green front dot and a two-dot rear. The frame is polymer with a black finish and the standard P365 grip texture for a consistent, familiar feel.
This model retains the P365-family modular FCU architecture for component compatibility, has left-side controls with no external manual thumb safety, and includes SIG’s proprietary single-slot accessory rail. Capacity is 12+1 with the included 12-round magazine. Manufactured in Newington, New Hampshire, USA.
