SHADOW SYSTEMS SS-1306 MR920 9mm | 15rd | Optic-Ready

The Shadow Systems MR920 Foundation is a compact, optic-ready 9mm pistol built on the Foundation Series frame with ergonomic controls and interchangeable backstraps. It features an optic-cut slide, serrations, and fixed steel sights for robust, everyday carry suitability and consistent sight picture. The MR920 ships with two magazines and three backstraps to tailor grip fit and control.

For mounting a red-dot optic under $1,000, the Holosun 507C is a compatible, widely used option that pairs well with this platform while preserving sight geometry and durability. Typical applications include everyday carry (EDC) and range/practice or production pistol competition where a compact, optic-ready platform is desirable.
