Abstract: A protective pistol holster with one-way safety device includes a protective holster main sandwich with several clamping devices, a pair of clamping and receiving members with triangular and trapezoidal configurations, two strip-shaped spring leaves, and a frame protecting cover. An expanding member is formed at the fold of the protective holster main sandwich. The clamping and receiving members, with triangular and trapezoidal structures, position the pistol body where the expanding member presses against the protective holster main sandwich with the assistance of the tightly forcing resilience from the middle of two spring leaves. Removal of the pistol is achieved by pressing toward the inner side of the holster near the human body.
