The SL Raptor is a self-locking OWB Kydex thermoformed holster. It is pre-formed with a curved back with most of the detailed molding on the outer portion. This adds to both comfort and conceal-ability. The Raptor comes with belt loops for 1 1/2" and 1 3/4". It features a Chek-Lok (trigger guard lock) which is very intuitive and a rear sweat guard.
