The Shadow Systems CR-P kit converts an existing CR920 pistol into the CR920 Comp configuration. You get the 3.66" barrel and the matching QD (quick-detach) compensator assembly used on Shadow Systems' CR920 Comp model - packaged for drop-in installation on your current slide. The comp is contoured to align with the slide profile for a seamless, uniform look from ejection port to muzzle. Specs & features: Includes 3.66" barrel + QD compensator assembly All-steel compensator with nitride bronze finish for corrosion and wear resistance Tri-lug attachment method - quick disassembly of the compensator from the barrel Contoured to match the CR920 slide profile Drop-in upgrade - no smithing required Compatibility: This kit is engineered for the Shadow Systems CR920 pistol platform. It is NOT a generic 1/2x28 comp/barrel combo - the tri-lug interface is proprietary to Shadow Systems and the dimensions match the CR920 slide only. Confirm your host pistol is a CR920 before ordering, and allow a short break-in period before duty or match use.
