The Shadow Systems MR920 Combat is a feature-packed, compact-sized pistol that is designed to work with existing G19 holsters, magazines, and gear. The MR920’s frame features configurable ergonomics. Interchangeable backstraps allow shooters to adjust the grip angle to fit their natural point of aim.
