  • 15. 

    Which part of the M9 pistol sits between the firing pin striker and the firing pin?

    • Trigger block

    • Hammer block

    • Firing pin block

    • Slide stop

    Correct Answer
    A. Firing pin block
    Explanation
    The firing pin block is the part of the M9 pistol that sits between the firing pin striker and the firing pin. It is designed to prevent accidental discharges by blocking the firing pin from moving forward unless the trigger is pulled. This safety mechanism ensures that the pistol will only fire when intentional pressure is applied to the trigger, enhancing the overall safety of the firearm.

    Rate this question:

  • 16. 

    The slide of you M9 pistol does not lock fully forward. what is the probable malfunction?

    • The locking block and the lugs are cracked/burred or broken.

    • The firing pin block is broken

    • The feed ramp is damaged

    Correct Answer
    A. The locking block and the lugs are cracked/burred or broken.
    Explanation
    The probable malfunction for the slide of the M9 pistol not locking fully forward is that the locking block and the lugs are cracked, burred, or broken. This means that there is damage to the mechanism responsible for locking the slide in place, causing it to not fully engage and secure the slide in the forward position.

    Rate this question:

  • 17. 

    The free length of the m9 recoil spring should not be less than?

    • 5 in

    • 6 in

    • 12 in

    • 11 in

    Correct Answer
    A. 5 in
    Explanation
    The correct answer is 5 in. The free length of the M9 recoil spring should not be less than 5 inches. This is because the recoil spring plays a crucial role in absorbing and controlling the recoil of the firearm. If the free length is too short, it may not provide enough resistance to effectively manage the recoil, leading to potential issues with accuracy and reliability. Therefore, it is important to ensure that the free length of the M9 recoil spring is at least 5 inches.

    Rate this question:

  • 18. 

    You must replace the barrel of the m9 pistol if you find pitting in the bore area that exceeds

    • Two land in width and 1/8 inch in length

    • Two land in width and 3/8 inch in length

    • One land in width and 3/8 inch in length

    • One land in width and 1/8 inch in length

    Correct Answer
    A. One land in width and 3/8 inch in length
    Explanation
    If pitting is found in the bore area of the M9 pistol, it is necessary to replace the barrel if the pitting exceeds one land in width and 3/8 inch in length. This means that if the pitting is wider than the width of one land (the raised area between the grooves) and longer than 3/8 inch, it is considered excessive and the barrel should be replaced.

    • 4 inch

    • 3 inch

    • 2 inch

    • 1 inch

    Correct Answer
    A. 1 inch
    Explanation
    During preventive maintenance checks and service, cracks exceeding 1 inch on the M203 hand guard assembly would render it not fully capable. This means that if cracks on the hand guard assembly are longer than 1 inch, the functionality and effectiveness of the assembly may be compromised. Therefore, it is important to identify and address any cracks exceeding this length to ensure the proper functioning of the M203 hand guard assembly.
