Before performing maintenance on a firearm, how should you verify that it is unloaded?

• A. Open the action and visually inspect the chamber.
• B. Remove the magazine, lock the slide open, visually and physically inspect the chamber and magazine well.
• C. Wipe down the grip and stored magazines.
• D. Check the serial number against a tester.

Answer: (B)

The main idea is to confirm there is no ammunition anywhere that could cause an accidental discharge while you work. Remove the magazine, lock the slide open, and inspect both the chamber and the magazine well. Removing the magazine eliminates any round in the feeding device. Locking the slide back exposes the chamber and lets you visually verify it’s empty and then physically check the chamber for any trace of a round. Inspecting the magazine well also ensures there isn’t a round seated in the mag well or a magazine that could feed a round when you reassemble. This approach covers all potential places ammo could be, making maintenance safer. Visually inspecting only the chamber could miss a round still in the magazine; wiping down the grip or magazines doesn’t verify unloaded status; checking the serial number is unrelated to whether the firearm is unloaded.
