Shadow Systems is now offering the MR920P/XR920P Comp and Barrel Assembly as an upgrade for your existing MR/XR920 pistol. This all-steel compensator is nitride coated for corrosion and wear resistance. The unique design is very spatially efficient allowing the compensated pistol to fit in holsters designed for G17 pistols. This assembly is a drop in kit to allow the use of the QD Compensator Assembly from the MRP/XRP. The compensator is designed to align with the contours of your slide to create a seamless appearance on your pistol. The barrel that is included in this kit utilizes a Tri-Lug style attachment method for quick disassembly of the compensator.
