Built on forged 4140 steel with a full-size frame and slide, this double-stack 9 mm pistol offers 17-round magazines, an RMSc/507K-compatible optics cut, and a five-slot Picatinny dust-cover rail—all at a manageable weight and price point.

The forged 4140 carbon-steel frame and slide provide service-grade strength while the black QPQ nitride and Cerakote finishes guard against corrosion and wear.
An optics-ready slide cut accepts RMSc-pattern and Holosun 507K footprint sights, letting the buyer mount a micro red-dot without additional machining.
The full-length, five-slot Picatinny rail on the dust cover allows mounting of weapon lights or lasers, making the pistol adaptable for duty, defense, or range use.
A skeletonized commander-style hammer and flat-faced Series-70 trigger promote a crisp, consistent single-action pull, while ambidextrous thumb safeties and a beavertail grip safety ensure familiar 1911 manual controls.
STI-pattern double-stack magazines deliver 17+1 rounds of 9 mm Luger in a full-size 1911 form factor, combining modern capacity with the platform’s proven ergonomics.
