The Aker Leather FlatSider XR7 Shoulder Holster (Aker part no. H107BPR-SS239) is molded for the SIG Sauer P239 and adapts Aker’s flatsiding process, originally developed for belt slide holsters, to shoulder carry. In the molding process, Aker uses a customized method to keep the back of the shoulder holster flat against your body while the fine contouring of the weapon comes through on the front. That combination creates a distinctive look and provides extra friction retention while keeping the holster pulled in close against the body instead of swinging loose.
