From the manufacturer: The MR920 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. 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. - The match-grade barrel is conventionally rifled and spiral-fluted to improve evacuation of debris. MR920s are also available with threaded barrels, for those departments that allow the use of muzzle devices.

The drop-safe, flat-faced aluminum trigger has a 4.5-5.0 lbs trigger pull and a crisp, tactile reset.

Optic cut models allow shooters to mount the mini red dot optic of their choosing. The optic cut on the MR920 can accommodate most major brands of RDS optics directly mounted to the slide, without intervening plates or adapters.*
