Named for the Bruce Nelson design, the FlatSider(TM) Statesman XR21 fills a very important niche. The belt loops on each end of the hoster wrap solidly around the belt and secure with heavy-duty, one-way snaps. This allows those who favor a slide-on holster the quick-on, quick-off convenience of a paddle rig, by simply snapping it on or off without removing the waistbelt. By featuring the same trigger guard tensioner and precision molding as our other Flatsider holsters, we again offer the user maximum speed and security. It features a strapless configuration for those who prefer this carry mode. The XR21 is a must have holster for detectives or off-duty use! NOTE: Not compatible with red dot optics
