The Shadow Systems SS-1309-1D MR920 Foundation Compact is a compact, optic-ready semi-automatic handgun chambered in 9mm with a 4″ threaded barrel and a 15+1 capacity. The slide/finish description in the product name indicates a black nitride slide paired with a bronze TiCN threaded barrel and an optic-ready cut.
