The slide is from a P365 AXG Legion and features an integrated two-port expansion chamber, front and rear cocking serrations, and an optic cut with the cover plate installed. It wears a light gray finish and is marked P365 with the stylized X. The barrel is marked 9mm x 19.
The serialized fire control unit and XSeries grip module are from the P365X. This micro 9mm package retains the P365X’s compact dimensions while offering a 12+1 capacity, a flat-faced striker-fired trigger, and a short SIG accessory rail ahead of the trigger guard.
Sight configuration is purpose-built for optics use: a SIG XRAY3 day/night front sight is installed, and there is no rear sight with the cover plate in place on the optic-cut slide.
Manufacturing and markings note its U.S. origin, with the frame marked NEWINGTON, NH USA. Documentation includes the factory case labeled with model code 365X-9-BXR3P and a date of March 31, 2025.
