This holster is extra comfortable because it's flat on one side! Using our special method, the FlatSider XR14 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.
