Started with a Sig AXG grip module and had it milled for a manual safety. The slide is a Sig Spectre slide we also had milled to fit a Bull Barrel. We upgraded the guide rod and spring to Armory Craft. Comes with Trijicon Suppressor Height Night Sights. And also comes with a Norsso 3.9" Bull Barrel and Streamlight TLR-7A. Never fired. Super smooth working the action.
