Product Summary

Derived from competition and built for duty use, the SDP Compact Alpha is the ideal gun to suit your needs on the job, in the home, or at the range. Every design feature on the SDP Compact Alpha is tailored to maximize performance, quality, and ergonomics. The competition inspired trigger is very smooth with a clean break and short, crisp reset. The steel slide is machined from billet and is hand-fitted to mate perfectly with the interior, full-length guide rails of the billet aluminum upper frame. The polymer pistol grip features interchangeable backstraps to adjust length and width of the grip; the grip inserts are specifically designed to maximize contact with the support hand for added control. Also for added control, the high trigger guard shape and beavertail allow for high hand placement on the pistol frame to compliment the low bore axis of the barrel, which allow the shooters to easily manage recoil. A Picatinny rail on the frame allow for the addition of modern tactical shooting accessories. The front and rear cocking serrations offer different options of firearm manipulation and the dotted front sight contrasts with the black rear sight for quick target acquisition. Ambidextrous features include the decocking lever and a magazine release that can be switched to either side. The slide release lever also serves as the takedown pin and is located on the left side of the Compact Alpha. This model has a 13.5 x 1 threaded barrel with a thread protector.
