The polymer grip module is textured for control and includes an integral beavertail. An integral multi-slot Picatinny rail on the dustcover supports mounting compatible accessories.
The matte black slide features front and rear serrations for confident manipulation, plus tapped holes on the slide top. Fixed, dovetailed sights include a white-dot front and square-notch rear for a clear, durable sight picture.
Ergonomics and controls include an ambidextrous slide catch, a left-side magazine release, and a curved trigger. The modular, serialized steel fire-control unit enables grip module changes, and takedown is tool-less and does not require a trigger press. Made in the USA.
