SHADOW SYSTEMS MR920 Foundation Compact 9MM 4″ | SS-1305

The SHADOW SYSTEMS MR920 Foundation is a compact, optic-ready 9mm pistol built around the Foundation slide profile. It combines a polymer frame with a 4″ Bronze TICN barrel and a black matte finish on the slide and frame. This model ships with a 15+1 capacity and is cut to accept RMR and compatible Holosun footprints; a good pairing under $1000 is the Holosun 507K red dot for its compact footprint and proven durability.

Common applications for this pistol include everyday carry (EDC) for users who prefer a compact sighting platform and competitive carry-class matches where a compact, optic-ready pistol provides an advantage.
