Figure 071-004-0001-4. Disassembly of the magazine

(1)  Grasp the magazine firmly, with the floor plate up and the back of the magazine tube against the palm of your hand.

(2)  Depress the locking block to make the locking block plunger protrude.

(3)  Using the locking block plunger, push down on the floor plate retainer stud.

(4)  Slide the floor plate slightly forward with your thumb.

(5)  While removing the floor plate, use your thumb to keep pressure on the magazine spring.

(6)  Remove the floor plate retainer, the magazine spring, and the follower from the magazine tube.

(7)  Remove the magazine spring from the follower.

(8)  Remove the floor plate retainer from the magazine spring.

3.   Clean the pistol and magazine.

CAUTION: Use the bore brush to clean only the bore. Using it on any other part of the pistol will cause damage.

a. Slide assembly.

(1)  Clean slide assembly with a cloth. Use CLP on a soft brush to remove excess dirt and carbon.

(2)  Wipe the slide assembly dry with a clean cloth.

b. Barrel assembly.

(1)  Attach a bore brush to a cleaning rod. Moisten the bore brush with CLP and insert it into the chamber end of the barrel. Make sure the brush completely clears the muzzle before you pull it back through the bore. Repeat this procedure several times to loosen carbon deposits.

(2)  To clean and dry the barrel, push a clean swab through the bore. Repeat as necessary with fresh swabs until a swab comes out clean.

(3)  Clean locking block with a soft brush.

(4)  Clean the recoil spring and spring guide with CLP and, if needed, a soft brush or cloth.

c. Receiver assembly. Wipe the receiver assembly clean with a cloth and, if needed, a soft brush.

d. Magazine (figure 071-004-0001-4).

(1)  Wipe the magazine tube and the follower with CLP, a cloth, and a soft brush.

(2)  Clean the magazine spring, floor plate retainer, and floor plate with a clean cloth.

e. Holster. Remove dirt from exterior with stiff brush. Wipe interior with clean cloth.

f.  Ammunition. If ammunition gets wet or dirty, clean it and remove corrosion from it at once using a dry cloth.

4.   Inspect for serviceability.

a. Slide assembly.

(1)  Check to ensure the ambidextrous safety moves freely.

(2)  Check the firing block for damage.

(3)  Check the rear sight for looseness.

b. Barrel assembly.

(1)  Inspect the bore and chamber for pitting or obstructions.

(2)  Check the locking block plunger to ensure the locking block moves freely.

(3)  Inspect the locking lugs for cracks and burrs.

c. Recoil spring and recoil spring guide.

(1)  Check recoil spring to ensure it is not bent or damaged.

(2)  Check recoil spring to ensure it is straight and free of cracks and burrs.

d. Receiver assembly.

(1)  Check for bends, chips, and cracks.

(2)  Check to ensure the slide stop and magazine stop move freely.

(3)  Check the guide rails for excessive wear, burr, cracks, or chips.

e. Magazine assembly (figure 071-004-0001-4).

(1)  Check for damage to the spring and follower.

(2)  Inspect magazine lips to ensure they are not bent excessively and that they have no cracks and burrs.

(3)  Check to ensure the magazine tube is not bent.

f.  Ammunition.

(1)  Check for damaged or corroded ammunition. Turn in heavily corroded or damaged ammunition.

(2)  Check to ensure ammunition is free of oil and grease.

5.   Lubricate the pistol and magazine.

Note. CLP, LSA, and LAW are the only lubricants authorized for this pistol.
Note. You can use CLP and LSA interchangeably.
Note. Before firing, remove excess lubricant from the bore.

a. Lubricate all parts with a light coat of LSA or CLP at temperatures above -10 degrees Fahrenheit, or LAW at temperatures below +10 degrees Fahrenheit.

b. Do not mix LAW with other lubricants.

6.   Assemble the pistol.

Figure 071-004-0001-5. Insertion of the barrel assembly


a. Grasp the slide with the bottom facing up (figure 071-004-0001-5).

b. With the other hand, grasp the barrel assembly with the locking block facing up.

c. Insert the muzzle into the forward end of the slide. At the same time, lower the rear of the barrel assembly by moving the barrel slightly downward with light thumb pressure. The barrel will fall into place.

d. Insert the recoil spring guide into the recoil spring (figure 071-004-0001-6).

Figure 071-004-0001-6. Recoil spring and spring guide

e. Insert the end of the recoil spring and the recoil spring guide into the recoil spring housing. At the same time, compress the recoil spring and lower the spring guide until it is fully seated on the locking block cutaway (figure 071-004-0001-7).

Figure 071-004-0001-7. Insertion of the recoil spring and guide


CAUTION: Be sure that the hammer is uncocked and firing pin block lever is in the down position. If the hammer is cocked, manually and carefully lower the hammer.  Do not pull the trigger while placing the slide onto the receiver.

f.  Push the firing pin block lever down. Grasp the slide and barrel assembly with the sights up, and align the slide on the receiver assembly guide rails (figure 071-004-0001-8).

g. Push until the rear of the slide is a short distance beyond the rear of the receiver assembly and hold. At the same time, rotate the disassembly latch lever upward. A click indicates a positive lock (figure 071-004-0001-8).

h. Assemble the magazine.

(1)  Insert the follower into the top coil of the magazine spring. Make sure the notches on the follower and magazine tube are on the same side.

(2)  Insert the magazine spring with follower into magazine tube.

(3)  Turn the magazine bottom up, with its back against the palm of the hand. Attach and center the floor plate retainer on the bottom spring coil.

CAUTION: After inserting the magazine spring, keep tension on it with your thumb. Be careful not to place the lips of the magazine tube on a hard surface while you reassemble the magazine.

(4)  Push and hold the magazine spring and floor plate retainer down. At the same time, slide the floor plate over the sidewalls until it seats fully.

(5)  Carefully insert the magazine into the pistol well. You will hear a click when it locks into position.

WARNING: Make sure the pistol is clear and unloaded.

7.   Perform a function check.

Evaluation Preparation:
