Compact, concealable, secure and versatile, the open muzzle design of the Silhouette makes it a favorite of gun carriers who own multiple barrel lengths of the same firearm model. The Silhouette features a reinforced thumb break for security, combat grip accessibility for speed, double-stitched seams for durability and covered trigger guard for safety. The retention strap configuration is specific to individual firearms types, and varies depending on firearm model. Fit belts up to 1.75".
