Abstract: A handgun holster comprising a holster assembly and a strap assembly. The holster assembly consists of a U-shaped exterior wall with top, bottom, and lateral edges. Extending from the top edge is a bend that defines a tension arm. Positioned within the exterior wall are bushings. The belt strap assembly has exterior and interior faces, third and fourth ends, and at least one hole. The belt strap assembly has female and male snaps adjacent to the ends. The male snap mounts onto a selected hole of the interior face by a screw that trespasses the first bushing and screws into a bolt. A second screw trespasses the second bushing and screws into a second bolt. The holster assembly is worn in between a waistband of an article of clothing and a belt. The tension arm is fitted over the waistband and the belt strap assembly wraps around the belt.
