With the aid of Don Hume's new HRTL (hidden retention trigger lock) locking device, the company's Jacket Slot Style Level 2 Security holster automatically secures a gun as it's re-holstered. A retention lock enters the trigger guard so the gun will rest safe and secure. To activate simply release the low-profile thumb break and continue moving thumb downward to release the secondary trigger guard release. With a shooter's grip, simply lift the gun straight up. To re-holster, insert gun, and push down to be sure the trigger guard lock is in place, securing the gun. A thumb break snap provides extra security.
