The 1791 Gunleather Combo Open Top Multi-Fit Belt Holster 2.1 and Mag 1.2 is a pancake-style holster that holds your gun and ammo tight using natural pressure between double-stitched leather and a weeks-long, wet-molding process. It is ideal for use on duty, on the range, or in the field, with extra carrying capacity and all-day comfort in mind. As with our other open top holsters, you'll get a quicker, more confident draw without unnecessary security features in your way. Also works with Double Stack Mags.
