Pistol Assembly

I. Position the barrel in the slide so that:

• The muzzle of the barrel fits in the hole in the front of the slide.

• The locking block portion of the barrel fits within the ejection port and the angled locking surfaces of the locking block are visible along the bottom of the slide.

2. Place either end of the recoil spring over the front end of the recoil spring guide rod.

3. Install the recoil/buffer spring assembly into the slide so that the front of the recoil spring guide rod engages in the small hole provided in the front of the slide.

4. Compress the recoil spring slightly and align the opposing angled locking surfaces on the rear end of the recoil spring guide rod with those located on the bottom of the barrel locking block. (See Figure 32A & B)

5. Push the rear of the recoil/buffer spring assembly forward enough so that the recoil spring retainer can be engaged on the shelf provided on the front of the barrel locking block. (See Figure 32A, B, & C)
