Shadow Systems XR920 Foundation | 9mm 4in | SS-3306

The Shadow Systems XR920 Foundation is a striker-fired 9mm pistol featuring a 4-inch barrel and an optics-ready foundation slide built on a full-size frame with a compact top end. The design emphasizes practical ergonomics, interchangeable backstraps, and an optic cut that accepts many popular micro red dots. For a quality sighting solution under $1,000 that pairs well with this platform, consider a Holosun 507C-series micro red dot for its footprint compatibility and proven track record.

This pistol is suitable for everyday carry (EDC) and range/practical shooting where an optics-ready platform and higher capacity are valued. It ships with two 17-round magazines and multiple interchangeable backstraps for fit customization.
