Abstract: The invention relates to devices for carrying small arms. The inventive method provides for use of a holster having a slot for a pistol grip. When a pistol is straightwardly pushed in the holster, the safety-stop thereof is switched in armed position. The pistol is removable by the opposite displacement thereof. The body of the inventive holster comprises guides for a breechblock, a spring loaded lock thereof, and a unit for switching said breechbloc which is arranged on the sidewall of said body on the side of the safety-stop of the pistol and embodied in the form of a spring loaded fork. The lock is embodied in the form of a cantilever plate provided with an arrester which is mounted in such a way that it interacts with the breechblock and the indicator of the safety-stop when it is switched on. In the second variant, the switching means is embodied in the form of a shaped window which has a simple trapezium shape and is arranged on the sidewall of the body.
