The X-Macro series configuration delivers a 17+1 capacity in a micro-size format. This example uses the Macro-Compact grip module and comes with two factory 17-round magazines designed for the P365 series.
The optics-ready X-Series slide includes a removable cover plate, with the rear sight mounted on the optics plate. Front and rear serrations provide positive manipulation, and the dovetailed green-dot front pairs with a square-notch rear.
The modular, serialized FCU architecture allows the fire control unit to be the legal core of the pistol, working within the polymer grip module that accepts interchangeable backstraps. This pistol includes L and M backstraps to tailor grip size.
Key operating features include a striker-fired, locked-breech action and a flat-faced trigger. The dustcover carries a full-length MIL-STD-1913/Picatinny rail for mounting compatible accessories. The pistol has no external manual thumb-safety and is made in the USA.
