The Pro Elite configuration pairs a 5-inch stainless steel barrel with a linkless, V-ported design to reduce muzzle rise and deliver consistent cycling. The slide features lightening cuts and a top window, with an optic cut and a removable cover plate.
The 7075 aluminum frame incorporates Debris Clearance Channels and a MIL-STD-1913 accessory rail on the dustcover. An integral flared magwell and aggressive raised pyramid grip texture support fast, confident reloads and secure handling.
Controls are fully ambidextrous, including a dedicated right-side slide stop and ambidextrous thumb safeties. A reversible magazine release allows setup to user preference. The flat-faced, pro-tuned trigger and skeletonized hammer provide a crisp, single-action-only, hammer-fired operation.
The optics-ready, co-witness multi-plate system includes plates for Trijicon RMR, Leupold DeltaPoint Pro, and RMSc/Holosun-K footprints. Night Fision tritium iron sights are installed, with an NF H3 orange-ring tritium front and a rear sight positioned in the optics-plate location for co-witnessing capability.
This full-size 9mm runs on SIG Sauer P320-pattern double-stack magazines and ships with a total of five magazines. Capacity is listed at 21+1, and the pistol wears a two-tone tan/black finish. Markings include "OA 2311" on the slide and "OA DEFENSE DAYTON, NV" on the frame.
