The Shadow Systems XR920 Elite was developed by request for law enforcement. The XR920 is a crossover pistol and incorporates a compact 4" top end with a full-size grip capable of holding 17 rounds. The XR920 is compatible with Glock G19 holsters. The XR920 features an extended beavertail, recoil control ledge and aggressive trigger guard undercut for grip control. The addition of an interchangeable backstrap system allows the user to adjust the angle of the grip to better match the shooter's aim. Includes optional magwell. The XR920 Elite slide is machined with directional serrations with a thinned profile at the grasping areas for a positive grip. The Elite includes weight reducing slide window cuts and top serrations. The drop-safe flat faced trigger has a 4.5 - 5 lb trigger pull and a crisp, tactile reset. Optics cut models can accommodate major brands of mini red dots without the use of an adapter. The new XR920 is the crossover pistol that is quicker out of the holster with a full 17+1 capacity. Featuring the customizable ergonomics and unmatched recoil control you expect from a Shadow Systems pistol, the XR920 is mission ready. 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 CALIBER: 9MM MAGAZINE (1) 17rd capacity BARREL: Spiral Fluted Threaded SLIDE Window Cut w/ Optic Ready OPTIC: Holosun 507C Red Dot SIGHTS: Front green Tritium, Rear Serrated GRIP Polymer.
