Shadow Systems XR920 Elite Optic Ready Features The Shadow Systems XR920 Elite slide is designed for manipulation under stress with directional serrations in the front and rear and a thinned profile at grasping locations. The match-grade barrel is conventionally rifled spiral-fluted and threaded. 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 Shadow Systems XR920 Elite can accommodate most major brands of RDS optics directly mounted to the slide without intervening plates or adapters.
