The Bianchi foldaway holster, Sz10 fits most single stack pistols while the Sz16 fits most double stack pistols. The foldaway is ideal when moving through carry/no-carry zones in that you just lay it flat on the belt instead of removing it. Made of premium, full grain leather, the 101 holster offers a unique carry option. The holster uses the belt as the "interior" of the holster while a trigger guard cutout retains the gun. Fits up to 1.5 in. (38 mm) belt width.
