What is the purpose of a slide lock or slide stop, and when should it be used?

• A. To release the trigger after firing.
• B. To lock the slide open after the last round or during maintenance; ensures chamber is empty for safe handling.
• C. To power the firearm.
• D. To engage the safety.

Answer: (B)

The slide lock or slide stop is a mechanical control that holds the slide in the rearward position. This gives you a reliable indication that the chamber is empty and allows safe handling. When the last round is fired, the slide moves back and the slide stop catches, keeping the slide open so you can clearly see there’s no round in the chamber and you can remove the magazine or inspect the chamber. It’s also used during maintenance to keep the slide locked open while you clean or inspect the firearm. It’s not meant to power the gun, and it’s not the firearm’s safety; those functions are separate.
