CA-FSC Firearm Cleaning and Maintenance Safety Flashcards

What should you inspect the barrel bore for before shooting?

Answer: Any obstructions that could cause a barrel burst

Always inspect the bore for any obstruction before shooting — even a small blockage can cause catastrophic barrel failure when fired.

What is a 'hangfire'?

Answer: A round that fires with significantly delayed ignition after the trigger is pulled

A hangfire is a delayed ignition where the cartridge fires seconds after the trigger is pulled, requiring careful handling to avoid injury.

If you pull the trigger and the firearm does not discharge (a misfire), what is the correct procedure?

Answer: Keep the firearm pointed safely downrange for at least 30 seconds before carefully opening the action

After a misfire, keep the firearm pointed in a safe direction for at least 30 seconds to guard against a hangfire before slowly opening the action.

What is a 'squib load' and why is it especially dangerous?

Answer: A round that fires with insufficient power, potentially lodging a bullet in the barrel

A squib load fires with insufficient pressure, often leaving a bullet stuck in the barrel — firing another round into the obstruction can cause catastrophic barrel failure.

What is the 'tap-rack-assess' technique used for?

Answer: A standard malfunction clearance drill for semi-automatic pistols

The tap-rack-assess technique — tapping the magazine base, racking the slide, and assessing — is the standard immediate action drill for clearing common semi-automatic pistol malfunctions.

What is the final safety step after completing firearm maintenance?

Answer: Confirm the firearm is unloaded and secure it in safe storage

The final step of every maintenance session is to verify the firearm is unloaded and then store it safely in a locked container or with a secure locking device.
