Shadow Systems SS3022AM: The MR920 is a feature-packed, compact-sized pistol that is compatible with existing G19 holsters, magazines and gear. The MR920s frame features configurable ergonomics. Interchangeable backstraps allow shooters to adjust the grip angle to fit their natural point of aim. An extended beavertail and aggressive trigger guard undercut work to dramatically reduce recoil and increase control. The frames wrap-around grip texture is aggressive enough to keep the gun firmly in the shooters grip without being uncomfortable for daily wear. The MR920 features a thinned profile slide at grasping locations and directional serrations in the front and rear; the match-grade, threaded barrel is conventionally rifled and spiral-fluted; drop-safe, flat-faced aluminum trigger with a crisp, tactile reset. Optic cut models allow shooters to mount the mini red dot optic of their choosing. The optic cut on the MR920 can accommodate most major brands of RDS optics directly mounted to the slide, without intervening plates or adapters. Includes Aimpoint Acro red dot.
