This video provides a detailed review of the 80% Arms GST-9, a modular pistol frame designed to accept Glock 19 Gen 3 upper assemblies. The reviewer highlights its ergonomic improvements over standard Glocks, including enhanced texturing, a flared mag well, and customizable backstraps that allow for Glock 17 magazine compatibility. The optic-ready slide with RMR/407c cut and front serrations are also noted as significant features.
