It has a leather Velcro strap retention device that features a leather thumb break snap, as well, as a Velcro option to remove the entire snap. The inside holster strap is adjustable to ensure a great fit for your handgun. The holster is backed with genuine, vegetable tanned sheepskin for serious comfort.
