During the dummy ammunition function check, which step in the cycle of operations cannot be verified?

• A. Ejecting
• B. Chambering
• C. Feeding
• D. The firing step.

Answer: (D)

Dummy ammunition is inert and cannot produce ignition, so it lets you verify mechanical cycling without firing a shot. You can see the slide feeding a round from the magazine, chambering it, and then ejecting it as the cycle repeats. The step that cannot be verified with dummies is the firing step, because there’s no primer or powder to ignite and no discharge to observe. In practice, you can still check triggering function with dry-fire (no ammo) or other safety checks, but with inert dummies you can’t confirm that the gun will actually fire.
