A firearm includes a receiver, a lower receiver, a magazine supported by a magazine catch, a grip, a bolt and a bolt-slide, and a slide catch lever. The bolt and bolt-slide are moveable during the firing procedure of a shot. The slide catch lever automatically blocks the bolt-slide when the magazine is empty. The firearm also includes a moveable ergonomic control group that includes a control button to eject the magazine and activate the slide catch lever. The moveable ergonomic control group also includes a vertical rod, which extends above from the button as far as the slide catch lever. The moveable ergonomic control group is manually activated by the user with the same hand holding the grip.
