The Foundation Series MR920 is a compact model built around a 4 in slide and barrel, balancing concealability with shootability. Its 416R stainless steel barrel is unthreaded for a clean, carry‑focused profile.
The slide features front and rear serrations, a beveled muzzle, and a direct‑mount optics cut with a cover plate. The included multi‑footprint hardware supports mounting popular pistol red dots directly to the slide.
The polymer frame uses interchangeable backstraps that change the grip angle, along with a high undercut trigger guard and extended beavertail. A Glock‑style accessory rail accepts compatible lights or accessories.
Steel sights pair a white‑dot front with a plain black rear. The striker‑fired action uses a flat‑faced polymer trigger with a trigger safety. Capacity is 15+1, with an unloaded weight around 22 oz and approximate dimensions of 7.1 in OAL, 4.8 in height, and 1.2 in width.
Made in the USA, this MR920 carries Shadow Systems part number SS-1306 and an MSRP of $679.
