The Shadow Systems MR920 Foundation 9mm is a compact, optic-capable semi-automatic handgun intended for range use and everyday carry. Its Foundation slide and compact dimensions make it suitable for shooters who want an optic-ready 9mm platform that works with common Gen 4 G19 holsters and accessories.
The MR920’s frame offers configurable ergonomics with interchangeable backstraps to tailor grip angle and fit. An extended beavertail and an aggressive trigger guard undercut reduce muzzle flip and improve controllability, while the wrap-around grip texture helps maintain a secure hold without being overly abrasive for regular carry or range sessions.
