What is the purpose of performing a chamber check after clearing a jam?

• A. To confirm the magazine is loaded.
• B. To verify the chamber is empty before resuming activity.
• C. To test the trigger's pull weight.
• D. To lubricate the slide.

Answer: (B)

After clearing a jam, you want to make sure the firearm is truly safe to resume use. The chamber check confirms that no live round remains in the chamber and that the action can cycle normally before you reload or resume firing. This step prevents an unexpected discharge if a round is still present or if the slide is manipulated again.

To do a chamber check, point the firearm in a safe direction, lock the slide back or pull it to the rear, and visually inspect the chamber and feed ramp to verify there’s no cartridge there. You may also feel for a round at the chamber opening to be certain it’s empty. Once you’ve confirmed the chamber is clear, you can proceed with safe loading and operation.

The purpose isn’t to verify the magazine is loaded, test the trigger pull, or lubricate the slide, so those steps aren’t the goal of a chamber check.
