The Aker FlatSider™ XR13 Open Top Belt Slide Holster provides a classic leather carry option with an open top design for fast, smooth access to your firearm. Designed for off-duty and concealed carry, this strapless holster eliminates the thumb break for an unencumbered draw while still offering secure retention through an adjustable tension screw.

With a mid-ride and FBI forward cant, the XR13 sits comfortably on the hip and promotes a natural draw motion, making it a versatile choice for everyday carry. A built-in sweat shield protects your body and the gun’s finish, improving comfort during extended wear. Molded belt slots allow the holster to slide easily onto belts up to 1-3/4 inches wide.

Unlike the XR12 model, the XR13 uses an open top design without a thumb break strap, offering quicker access while still maintaining dependable retention thanks to the tension screw. This strapless configuration makes it popular with both concealed carriers and law enforcement personnel who do not require active retention.
