Designed around the proven 1911 manual of arms, the Platypus 320 delivers single-action, hammer-fired operation with a flat-faced, skeletonized trigger and a skeletonized commander-style hammer. A high undercut trigger guard and upswept beavertail grip safety promote a high, consistent grip, while the SA-branded flared magwell speeds reloads.
The slide integrates machined traction features for confident manipulation and a lightening window for weight reduction. Sights include a dovetailed green fiber-optic front, and the slide is optics-ready with a cover plate; rear sight/optic configuration may vary.
The frame features a full-length 1913 Picatinny accessory rail on the dustcover, a textured magazine release, and geometric textured grip panels. The pistol wears a matte black finish with blue-accented controls and trim for a distinct, modern look.
Engineered to accept SIG P320-pattern double-stack magazines, this full-size 9mm offers a 17+1 capacity and ships with two 17-round magazines. It is manufactured in Celina, Ohio, USA.
