Overview

Built for shooters who want a compact 9x19mm Luger pistol with modern handling features, this model combines a true double-action striker trigger with the updated ergonomics of the Gen2 line. The improved grip texture, flared magazine well, and 1913 Picatinny accessory rail make it a practical choice for range use or as a carry-oriented setup where a smaller frame is preferred. Its gray frame and black slide give it a restrained two-tone finish, while the included 17-round magazines add useful capacity. The compact barrel and grip size make it the smallest option in the series, which may appeal to users prioritizing a smaller footprint over a full-size feel.
