General disassembly is the disassembly necessary for normal care and cleaning. To field-strip the service pistol, perform the steps in the following order:

1. Hold the pistol in the raised pistol position, press the magazine catch, and remove the magazine, as shown

in figure 3-30, for a right-handed firer. The left-handed firer should reverse hands for this procedure. Pull the slide to the rear and inspect the chamber to see that the weapon is clear. Press down on the slide stop and allow the slide to move forward. Press the thumb safety lock upward to the SAFE position.

2. Press down on the recoil spring plug and turn the barrel bushing one-fourth turn clockwise, as shown in figure 3-31. Allow the recoil spring to expand slowly, under control, to prevent injury or loss of the part and remove the plug. Turn the recoil spring plug counterclockwise and remove it. Leave the recoil spring in place.

3. Press the thumb safety lock downward to the FIRE position. Push the slide to the rear until the disassembly notch, as shown in figure 3-32, is aligned with the rear projection on the slide stop. Press the protruding end of tie slide stop, and then pull out the slide stop.

4. Pull the receiver rearward to separate it from the slide, as shown in figure 3-33.

Figure 3-35.-Barrel bushing removal from the slide.

Figure 3-36.-Barrel removal from the slide.

5. Remove the recoil spring guide and recoil spring, as shown in figure 3-34. Separate the two parts with a twisting action.

6. Remove the barrel bushing by turning it counterclockwise, as shown in figure 3-35, and pulling it from the slide.

7. Push the barrel link forward and remove the barrel from the front end of the slide, as shown in figure 3-36. This completes the field-stripping. Observe figure 3-37. It shows the parts of the pistol in the order of the field-stripping just completed.

ASSEMBLY

To assemble the pistol after the field-stripping procedure, replace the parts in the reverse order of the disassembly.

Figure 3-37.-Parts of the pistol in order of field-stripping.

1. BARREL. Push the barrel link forward on the barrel and replace the barrel, chamber end first, in the slide. (See fig. 3-36.)

2. BARREL BUSHING. Place the barrel bushing on the muzzle end of the barrel, push it into the slide, and turn it clockwise. (See fig. 3-35.)

3. RECOIL SPRING AND RECOIL SPRING GUIDE. Insert the recoil spring guide into the tightest end of the recoil spring. Replace these parts in the slide. (See fig. 3-34.) Be sure the concave cut on the recoil spring guide collar is properly seated in the barrel. Push the barrel, recoil spring, and recoil spring guide frilly forward in the slide, ensuring that the barrel link is positioned forward and rests against the hole in the recoil spring guide. (See fig. 3-33.)

4. ASSEMBLING THE RECEIVER GROUP TO THE SLIDE GROUP. Hold the slide with the sights down in the palm of one hand. Invert the receiver (the safety lock must be in the FIRE position) and engage the guide rails of the receiver in the grooves of the slide. (See fig. 3-33.) Push the receiver all the way forward on the slide with a quick motion.

5. SLIDE STOP. Hold the pistol as shown in figure 3-33. Look through the slide stop pinhole in the receiver for alignment of this hole with the hole in the barrel link If the holes are not aligned, move the muzzle end of the barrel forward or rearward to align them. Insert the slide stop pin into the holes. Move the slide forward until the disassembly notch is over the square hole in the left side of the receiver. (See fig. 3-32.) Press the slide stop up and in to seat it fully. In some cases, a punch may be required to depress the slide stop plunger in order to seat the slide stop fully.

6. RECOIL SPRING PLUG. Push the slide frilly forward on the receiver and press the thumb safety lock upward to the SAFE position. Place the recoil spring plug on the recoil spring. Turn the recoil spring plug clockwise to lock the plug to the recoil spring. Holding the pistol, as shown in figure 3-31, insert the recoil spring and push downward on the recoil spring plug, compressing the spring until the plug is inside of the slide. Turn the barrel bushing counterclockwise to lock the recoil spring plug in place. Press the safety lock downward to the FIRE position and squeeze the trigger.

7. MAGAZINE. Insert the magazine into the magazine recess of the pistol until it is fully seated and held by the magazine catch. (See fig. 3-30.) This completes the pistol assembly.
