After insertion, magazine spring tension must be maintained using the index finger. False

Lesson 3 – Safety/Function CheckThe M9 Service Pistol is mission ready after conducting a successful safety/function check. True

Lesson 5 – Safe Handling and Movement ProceduresIn the Administrative Transfer the M9 Service Pistol condition is:Condition 4 with the slide locked to the rear.

A round can remain chambered in the M9 Service Pistol after removal of the magazine. True

When is a loaded chamber indicator check made? After a round has been chambered.

Which procedure is associated with the following steps: Make Ready1. Firmly grip the pistol with the firing hand. Ensure the pistol is pointed in a safe direction, with the slide

in the forward position. 2. To facilitate pulling the slide to the rear, rotate the magazine well outboard. With the fingers and thumb

of the non-firing hand, grasp the serrated sides of the slide just forward of the safety. 3. Pull the slide to its rearmost position by pushing forward with the firing hand while pulling back on the

slide with the non-firing hand. 4. Release the slide. This action will strip a round from the magazine and chamber it as the slide moves

forward. 5. Check to ensure a round has been properly chambered by checking the extractor/loaded chamber

indicator on the right side of the pistol.

Which procedure is associated with the following steps: Load1. Ensure the pistol is in Condition 4. 2. With the firing hand firmly gripping the pistol and the pistol pointed in a safe direction, rotate the pistol

so the magazine well is inboard and clearly visible. Draw the firing elbow in to facilitate control of the pistol, keeping the muzzle pointed in a safe direction.

3. With the non-firing hand, remove a filled magazine from the ammunition pouch. To ensure the magazine is filled, slide the index finger along the forward edge of the magazine until the finger is

touching the tip of the round. This step is referred to as indexing the magazine. The extended finger can also act as a guide in lining the magazine up with the magazine well.

4. Insert the filled magazine into the magazine well, verifying orientation of magazine with index finger. With fingers extended, push the magazine with the heel of the hand until it is fully seated. Do not relinquish control of the magazine until it is fully seated.

5. The weapon is now in Condition 3.

Which procedure is associated with the following steps: Unload1. With the firing hand firmly gripping the pistol, ensure the pistol is on safe by pressing the

decocking/safety lever down. 2. Rotate the pistol so the magazine well is pointed inboard and angled down. 3. Depress the magazine catch to remove the magazine from the pistol. Catch the magazine with the non-

firing hand and stow on person. 4. Push upward on the slide stop with the firing thumb while maintaining pressure. Rotate the pistol so the

chamber is outboard. 5. Reach over the top of the pistol with the non-firing hand and grasp the slide serrations. The non-firing

hand should partially cover the ejection port, positioned to catch an ejected round. 6. With the pistol pointed in a safe direction, fully retract the slide and lock it to the rear. At the same time,

catch the ejected round with the non-firing hand. 7. Rotate the pistol so the inside of the chamber is visible. Visually inspect the magazine well and

chamber to ensure they are empty

Which step is common to both the individual transferring the weapon and the individual receiving the weapon. Visually inspect the pistol to ensure it is safe and clear.
