Blackhawk CQC Serpa Holster Left Hand Fits Glock 43, Polymer - Black The Serpa holster has become one of the most popular holster platforms for law enforcement, military personnel and responsible citizens. Featuring two levels of retention, the Serpa CQC Concealment Holster delivers unmatched performance in the areas of speed and reliability. A patented Serpa auto lock release reinforces a full master grip by allowing users to draw the weapon normally with the index finder sliding from the holster body to the weapon frame in one single movement. Upon re-holstering, the auto lock immediately engages the trigger guard with an audible click and won't let go until you manually release.
