One of the things you can be absolutely certain of when you buy a Wilson Combat® firearm is that you are purchasing reliability. Our Sentinel® model comes with this same guarantee, plus maximum concealability. The Sentinel® is a precisely engineered 9mm with a scant 7.25” overall length, weighing in at only 32 ounces fully loaded and ready to fire. We developed a 3.6” bull barrel for the Sentinel® with a tapered cone to concentrate as much weight as possible towards the muzzle, and coupled this with a full-length guide rod. The Sentinel® has cocking serrations on the rear of the slide and carry cuts at the front of the slide.
