Featuring the customizable ergonomics and unmatched recoil control you expect from a Shadow Systems pistol, the XR920 is mission ready. The XR920 frame features interchangeable backstraps to allow a shooter to adjust the grip angle to fit their natural point of aim. The optic cut on the XR920 can accommodate most major brands of RDS optics directly mounted to the slide, without intervening plates or adapters. This pistol is chambered in 9mm with a 4.5 inch threaded barrel and 17 round capacity.
