Experience the most natural Level III draw on the market with the patented SERPA Auto Lock™ by Blackhawk . This technology allows users to disengage with one swift motion of the trigger finger sliding from the molded channel on the outside of the holster to the weapon frame. There is no awkward middle finger release or thumb break to slow user down. Auto Lock also guarantees immediate security by activating the trigger guard when reholstering and will not release until user does so manually. .
