First Shots: Shadow Systems XR920 Combat Optics Ready Review

The XR920 is Shadow Systems’ take on a Glock 45-style gun—a crossover between a full-size grip and a compact-length slide. It’s optics-ready, comes with a match-grade fluted barrel, aggressive slide serrations, an enhanced magwell, and their proprietary optics mounting system.

Think Glock 17 grip length with a Glock 19 slide profile, but refined everywhere Glock left “good enough.”
