The present disclosure relates to an automatic or semiautomatic pistol including a slide and a magazine. The magazine feeder includes an actuator that controls a slide stop. The slide stop, located rearward of the magazine, is designed to switch from a low to a high position. In its high position, the slide stop locks the slide in a rearward position. The pistol also includes a control lever for the slide stop, which is attached at one end to rotate about a pin forward of the magazine. The control lever includes a feeler that is lifted by the control actuator when the magazine is empty, causing the slide stop to switch from its low to high position. The slide stop may have ambidextrous manual releases rigidly connected to each other across the pistol.
