Built on the 2011 platform, this single-action-only, short-recoil-operated pistol pairs a 5 in linkless barrel with an external hammer and a flat-faced, skeletonized trigger. The polymer grip module features molded texture with OA logo panels and a flared, screw-retained magazine well for faster reloads.
The slide is optic-ready with a cover plate and uses a multi-footprint optics-plate system for broad red-dot compatibility. Distinctive machining includes top and side lightening windows, a faceted top, and rear grasping serrations for confident manipulation.
Controls are set up for versatility: ambidextrous manual thumb safeties, ambidextrous slide stop levers, and a reversible magazine release. A beavertail grip safety with a memory pad promotes consistent engagement.
The full-length dustcover integrates a Picatinny accessory rail, and the sighting setup includes a dovetailed green fiber-optic front sight; rear sight configuration may vary with the optics plate or optic installed. The pistol uses SIG P320-pattern double-stack magazines and comes with both standard-length (17-round) and extended (21-round) options. Made in the USA.
