The Shadow Systems MR920 9mm Foundation Slide Pistol is a feature-packed compact-sized pistol that is designed to work with Gen 4 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. An extended beavertail and aggressive trigger guard undercut work to dramatically reduce recoil and increase controllability. The frame's wrap-around grip texture is aggressive enough to keep the gun firmly in the shooter's grip without being uncomfortable for daily wear.

The MR920 slide has a thinned profile at grasping locations and directional serrations in the front and rear (as well as topside on some models) for easy manipulation under stress.
