GSI Firearms Handling & Safety Protocols 4 — Questions and Answers
Question 1: A GSI is running a qualification course and a student's firearm locks open after the last round. What does this indicate about the firearm's condition?
- The firearm has malfunctioned and requires immediate repair
- The magazine is empty and the slide or bolt has locked back — the firearm is empty (Correct answer)
- The extractor has failed and the case is stuck in the chamber
- The recoil spring is broken and the slide cannot return to battery
Correct answer: The magazine is empty and the slide or bolt has locked back — the firearm is empty
Most semi-automatic firearms lock the slide back on an empty magazine as a visual and tactile indicator that the gun is empty and needs to be reloaded.
Question 2: What is the correct protocol when a firearm fails to fire (no bang, no click) during a timed qualification stage?
- Immediately eject the cartridge downrange
- Keep the firearm pointed downrange for at least 30 seconds before opening the action (Correct answer)
- Immediately open the action to inspect the chamber
- Shake the firearm to dislodge the round and continue shooting
Correct answer: Keep the firearm pointed downrange for at least 30 seconds before opening the action
A hangfire (delayed ignition) can occur up to 30 seconds after the trigger is pulled, so the muzzle must remain downrange before the action is opened.
Question 3: A student's revolver shows a gap between the cylinder face and the barrel. Why is it important for a GSI to address this?
- It reduces muzzle velocity and accuracy
- Hot gases and debris escape the cylinder gap and can injure anyone whose hands cross in front of it (Correct answer)
- A large cylinder gap always indicates a timing problem requiring immediate repair
- The gap allows foreign objects to enter the action
Correct answer: Hot gases and debris escape the cylinder gap and can injure anyone whose hands cross in front of it
The cylinder gap on a revolver releases high-pressure gases and sometimes lead particles, making it essential that support hand fingers never extend in front of the cylinder.
Question 4: A range student is observed using a laser sight during low-light drills and accidentally points it toward other shooters. How should the GSI respond?
- Issue a verbal warning only, as laser pointers are not hazardous
- Immediately call a ceasefire and address the muzzle discipline violation, treating it the same as sweeping with a live firearm (Correct answer)
- Allow the exercise to finish and discuss it during the debrief
- Confiscate the laser sight for the remainder of training
Correct answer: Immediately call a ceasefire and address the muzzle discipline violation, treating it the same as sweeping with a live firearm
Sweeping other people with a mounted laser is a muzzle discipline violation; the laser is attached to the firearm's muzzle, and the same rules apply.
Question 5: Which of the following is the MOST important reason a GSI should teach students to keep the trigger finger indexed along the frame until ready to shoot?
- It prevents the trigger from being pulled accidentally during loading or movement (Correct answer)
- It allows faster target acquisition by pre-positioning the finger
- It is required by law in all 50 states
- It prevents the firearm from being grabbed by an attacker
Correct answer: It prevents the trigger from being pulled accidentally during loading or movement
Keeping the trigger finger indexed along the frame outside the trigger guard is the primary mechanical means of preventing an unintentional discharge.
Question 6: When teaching students about the four fundamental rules of firearm safety, a GSI should explain that the rules are designed to work:
- Independently, so violating one is always acceptable if the others are followed
- In layers, so that multiple rules must fail simultaneously for a negligent discharge to cause harm (Correct answer)
- Sequentially, with Rule 1 being the only rule that truly matters
- Optionally, at the discretion of the shooter based on experience level
Correct answer: In layers, so that multiple rules must fail simultaneously for a negligent discharge to cause harm
The four rules create layered redundancy — a negligent discharge only becomes a tragedy if two or more rules are violated simultaneously.
Question 7: A student wants to practice with a suppressor for the first time. What should the GSI advise regarding hearing protection?
- Hearing protection is unnecessary because suppressors make firearms hearing-safe
- Hearing protection is still strongly recommended because most suppressed firearms remain above safe hearing thresholds (Correct answer)
- Suppressors require double hearing protection due to mechanical noise
- Suppressors are illegal for civilian use and cannot be used in training
Correct answer: Hearing protection is still strongly recommended because most suppressed firearms remain above safe hearing thresholds
Most suppressed firearms still produce 130–140 dB of sound, well above the 85 dB threshold for hearing damage, so hearing protection remains advisable.
