The Shadow Systems MR/XR-P Compensator and Barrel Kit (brand part no. SGK-MRP-NIT) is an upgrade for an existing MR920 or XR920 pistol, pairing a 4.2-inch, 9mm barrel with an all-steel, nitride-coated compensator. The compensator’s spatially efficient design is slim enough that a compensated MR/XR920 still fits holsters built for a standard Glock 17, and it is contoured to align with the pistol’s slide for a seamless look rather than an obvious bolt-on unit. This drop-in kit uses the same QD compensator assembly as Shadow Systems’ MRP/XRP models, and the included barrel uses a Tri-Lug style attachment for quick compensator removal.
