At the pinnacle of the EVO SP line is our Custom shop model. Using modern machining techniques, the solid stainless-steel slide boasts modern weight saving style and Stiplex inspired slide serrations. Continuing to the frame, we added Stiplex inspired serrations in both the front strap and G10 grips to ensure positive retention in any situation. Also, included are upgraded TRUGLO TritiumPro sights and a 7-round magazine extended magazine. We topped this off with our patented KimPro II finish on the frame and an Ferritic Nitrocarburizing (FNC) slide to ensure long lasting durability. The Custom shop was designed in collaboration between our engineers and gunsmiths to provide the ultimate choice for concealed carry. The EVO SP (CS) ships with two 7 round magazines.
