During a dummy ammunition function check, which step cannot be verified?

• A. The firing step
• B. The locking step
• C. The ejecting step
• D. The extracting step

Answer: (A)

The key idea here is that dummy ammunition is inert—there’s no primer or propellant. A function check with dummy rounds focuses on the pistol’s mechanical cycling: can the magazine feed a round into the chamber, does the slide cycle properly, does the extractor grab the rim and pull the case out, and does the slide lock back when the magazine is empty. You can observe and verify feeding, extraction, ejection, and the locking action during the cycle. What you cannot verify with dummy ammo is the firing step, because there’s no primer to ignite and no powder to burn. There’s nothing to cause the firing pin to strike or a cartridge to discharge, so the actual firing portion can’t be tested with inert rounds.
