The XD-S Mod.2® OSP™ 4″ single-stack 9mm pistol combines impressive ballistic performance with optics-ready capability. Combining a compact, concealable frame with a 4” barrel for improved sight radius and enhanced ballistics, the pistol gives you the best of both worlds. Coming with both a flush-fit 7-round magazine and an extended 9-round magazine, the pistol also features a Crimson Trace micro red dot that sits low enough to allow you to effectively utilize the iron sights.
