The XR920 slide is designed for manipulation under stress, with directional serrations in the front and rear (as well as topside on some models) and a thinned profile at grasping locations. The match-grade barrel is conventionally rifled, spiral-fluted, and available threaded or unthreaded. The drop-safe, flat-faced aluminum trigger has a 4.5-5.0 lbs trigger pull and a crisp, tactile reset. The patented optic cut allows shooters to mount a mini red dot optic of their choosing. The optic cut on the XR920 can accommodate most major brands of RDS optics directly mounted to the slide, without intervening plates or adapters. Whether your pistol is your nightstand security blanket or your daily duty partner, there is a Shadow Systems pistol to fit the role. The XR920 is a perfect blend of the MR920 and DR920.
