Shadow Systems DR920 Elite Full-Size 9mm Semi-automatic Pistol Designed with officers and service members in mind, the Full-Size DR920 is a duty-ready Pistol with features that are anything but basic. It's designed to work with existing Glock 17 holsters, magazines, and gear-so you have tons of aftermarket support-and features one of the best optics mounting systems on the market. The DR920 frame features interchangeable backstraps to allow you to adjust the grip angle to fit your natural point of aim. The extended beavertail and aggressive trigger guard undercut provide unmatched recoil control, allowing quick, accurate follow-up shots. The frame's wrap-around grip texture is aggressive enough to keep the gun firmly in your grip without being uncomfortable for daily wear. The DR920 slide is designed for manipulation under stress, with directional serrations on the front, rear and top, and a thinned profile at grasping locations. A specially engineered window cut reduces weight and reciprocating mass for optimal recoil impulse. The barrel is machined from 416R stainless steel, and features conventional rifling-so it's compatible with lead bullets. The spiral fluting pattern improves evacuation of debris and reduces barrel weight, making the DR920 9mm ultra-lightweight. The Pistol comes outfitted with a flat-faced polymer trigger that breaks clean after a 4.5-5 lb. trigger pull. Finished off with a solid black metal rear sight and hi-viz green outline tritium front sight, the DR920 is the ultimate lightweight multi-role Pistol. More On the Optics Mounting System The new optics mounting system is among the best we've ever seen, and was the result of considerable effort. By redesigning internal slide components, Shadow Systems was able to relocate portions of the operating system to allow: 1. Strong, deep screw placement. 2. Extremely low placement for true co-witness with iron sights 3. Most importantly, direct mounting of
