The COMP variant uses a 3.1 in barrel paired with a slide that incorporates an integrated compensator, reducing muzzle rise without adding external devices. Forward and rear slide serrations aid manipulation, while the Nitron finish on the stainless-steel slide provides a durable, low-glare surface.
The XMacro grip module increases capacity to 17+1 rounds and includes a flared magwell for faster magazine changes. Interchangeable backstraps let the user tailor the grip size, and the full-length M1913 accessory rail with four slots supports common weapon-mounted lights and accessories.
Factory SIG XRAY3 day/night sights are installed: a tritium front with a green ring and a tritium square-notch rear for consistent visibility in varied lighting. The slide features an optic cut using the Shield RMSc footprint for direct-mount micro red dots that follow this pattern.
Built on the modular P365 FCU architecture, this striker-fired, locked-breech pistol uses a flat-faced trigger for a straight press and a left-side magazine release.
