Description

The Shadow Systems MR920 is a compact 9 mm striker-fired semi-automatic pistol designed for everyday carry, duty use, and range performance. It’s built with a Glock-compatible platform (holsters, magazines, and accessories fit), features configurable ergonomics with interchangeable backstraps, an extended beavertail and undercut trigger guard for better recoil control, and optic-ready slide options for mini red-dot sights. The slide and barrel machining focus on controllability, reliability, and ease of manipulation under stress.
