Blackhawk 44H000BKR: Based on the popular Serpa Tactical Holster, this jacket-slot belt-loop version gives both the tactical operative and patrol officer the option of SERPA\'s retention and speed in a duty-style holster. Whether worn as part of a duty rig or as a belt-mounted holster for tactical use, you get the same great Serpa technology with this Level 2 duty holster.
