The Shadow Systems MR920 Combat OSP is a compact 9mm pistol built for shooters who want optic-ready capability, refined ergonomics and G19-compatible handling in one platform. This FDE SS-1018 model features a 4-inch barrel, 15+1 capacity and two included 15-round magazines.
The MR920 Combat includes a flat-faced aluminum trigger, metal sights with a black rear and high-visibility green outline tritium front sight, plus a removable magazine well. Its NPOA backstrap system includes three backstraps, allowing the grip angle to better match the shooter’s natural point of aim.
Shadow Systems designed the MR920 frame with a recoil-control ledge on the dust cover to help manage muzzle movement during fast follow-up shots. The pistol is also compatible with many Glock Gen4 G19 holsters, magazines and accessories, making it practical for buyers already invested in that compact 9mm ecosystem.
