The Corvus quickly and easily converts from a belt holster to an inside-the-waistband design. With an open top for fast draw, adjustment for ride height and cant, virtually maintenance-free construction and comfortable forward molding, the highly versatile Corvus is a superior holster choice for defensive carry. Packaged set up for belt carry, the Corvus is swiftly and easily convertible to a highly concealable IWB holster. The Corvus comes complete with belt slots in both 1.75" and 1.50" widths, as well as straps for conversion to inside the waistband carry. The modern layout is designed to accommodate most carry-style optical sights, while the deep sight rail accommodates most suppressor-height sights.
