Our approach to this popular holster genre is extra comfortable because it's flat on one side! Using our special method, the FlatSider™ XR12 is molded in fine leather to fit one's handgun with 100% of the holster pocket formed away from the body No other holster can boast of this feature At either side of the holster pocket are curved belt slots that cooperate to provide stability on the belt with unparalleled concealment The thumb break configuration is backed up by an adjustable tension screw that does double duty as a trigger guard stop Inside the holster is a full-length molded sight channel and the special dual-plane muzzle is suited to both standard and shortened barrels
