ASO Firearms Safety and Proficiency 3 — Questions and Answers
Question 1: What is the recommended minimum distance a security officer should maintain from an armed subject before attempting weapon retention?
- Contact distance only
- At least 21 feet when possible (Correct answer)
- Three feet for optimal control
- The distance depends solely on backup availability
Correct answer: At least 21 feet when possible
The 21-foot rule (Tueller Drill) demonstrates that a determined attacker can close 21 feet before most officers can draw and fire, making distance a critical safety factor.
Question 2: When storing a service firearm at home, which practice best meets safety and security standards?
- Keep it loaded under the mattress for rapid access
- Store it unloaded in a locked safe, ammunition stored separately
- Place it on a high shelf out of children's reach
- Store it in a locked safe that can be quickly accessed while keeping it loaded (Correct answer)
Correct answer: Store it in a locked safe that can be quickly accessed while keeping it loaded
A quick-access locked safe keeps the firearm secured from unauthorized users while allowing the officer to retrieve it rapidly in an emergency — the industry-recommended balance of security and accessibility.
Question 3: A security officer experiences a failure to fire after pulling the trigger. After waiting 30 seconds, what is the next correct step?
- Re-pull the trigger immediately
- Eject the round immediately into your hand
- Keep the firearm pointed downrange and eject the cartridge carefully (Correct answer)
- Disassemble the firearm on the range to inspect the round
Correct answer: Keep the firearm pointed downrange and eject the cartridge carefully
After the mandatory wait for a potential hangfire, the officer should keep the muzzle pointed in a safe direction (downrange) and carefully eject the suspect round.
Question 4: Which part of a semi-automatic pistol strips a round from the magazine and chambers it?
- Trigger bar
- Recoil spring assembly
- Slide/bolt (Correct answer)
- Extractor
Correct answer: Slide/bolt
The slide (or bolt in rifle-type firearms) moves rearward under recoil, ejects the spent case, then moves forward stripping and chambering the next round from the magazine.
Question 5: Under what circumstance is it acceptable to point a firearm at a person during a security assignment?
- Whenever a subject is verbally uncooperative
- When authorized by policy and the officer reasonably believes there is an imminent threat of death or serious bodily harm (Correct answer)
- When a supervisor directs the officer to do so for crowd control
- Whenever a subject refuses to show identification
Correct answer: When authorized by policy and the officer reasonably believes there is an imminent threat of death or serious bodily harm
Pointing a firearm at a person is only justified when policy allows it and there is an objectively reasonable belief of imminent deadly threat — it constitutes use of force.
Question 6: What does 'indexing' the trigger finger mean?
- Placing the trigger finger along the frame above the trigger guard (Correct answer)
- Using the index finger to rack the slide
- Resting the trigger finger lightly on the trigger
- Keeping the trigger finger curled inside the trigger guard without firing
Correct answer: Placing the trigger finger along the frame above the trigger guard
Indexing means positioning the trigger finger straight along the frame or slide, above and outside the trigger guard, until the decision to fire has been made.
Question 7: Which type of round is most commonly recommended for security officers who must limit over-penetration risk in populated areas?
- Full metal jacket (FMJ)
- Hollow point (JHP) (Correct answer)
- Armor-piercing (AP)
- Frangible wadcutter
Correct answer: Hollow point (JHP)
Jacketed hollow point ammunition expands on impact, transferring energy into the target and reducing the likelihood of over-penetration compared to FMJ rounds.
