Slide stop

A slide stop, also referred to as a slide lock on a semi-automatic handgun is a function that visually indicates when a handgun has expended all loaded ammunition, and facilitates faster re-loading by removing the step of pulling back the slide to advance the first round of a new magazine; in many cases, this is achieved by replacing the magazine and activating a push-button or lever release to load the first cartridge into the chamber.
