SHADOW SYSTEMS DR920 Foundation | 9mm 4.5in | 17+1 | SS-2306

The Shadow Systems DR920 Foundation is a full-size, striker-fired 9mm pistol built on Shadow Systems’ Foundation frame. It ships with a 4.50 inch unthreaded match-grade barrel finished in nitride and an optics-ready slide that accepts most mini red-dot sights. The polymer frame includes interchangeable backstraps and an aggressive wrap-around texture for consistent control and feel.

For an optic under $1,000 that pairs well with the DR920’s cut, consider a Trijicon RMR Type 2 or a comparable mini red dot; the slide cut accommodates most major RDS footprints. Typical applications include everyday carry for shooters who prefer a full-size platform and dedicated range training or competitive pistol work.
