AUTO RETENTION HOLSTER

A retention block, mounted within a handgun receiving, holster shell cavity automatically locks a handgun therein upon its insertion into the holster cavity. An access passage is formed through a first sidewall of the holster shell. The retention block is mounted inside the holster cavity, selectively moveable from the locked position to an unlocked position by a retention-block release lever that is oriented on the outer surface of the first sidewall of the holster shell and coupled to the retention block through the access passage. A retention-block biasing element is coupled to the retention block, for biasing the retention block into the locked position.
