(1) Pistols which are damaged or give poor shooting results are to be examined by the armourer responsible for maintaining the pistol who is to:

- Ascertain the cause and extent of the unserviceability.

- Check spare parts if required.

- Determine whether the specified special tools or test equipment needed are available.

(2) Damaged components must be replaced with new ones.

(3) Each time that the pistol is repaired it must be subjected to a full functional check.

4.3.1 Stripping the slide

Strip the pistol as described in Section 3.2. - Remove the safety catch (3) using an assembly mandrel to push the firing pin (18) forwards, at the same time pushing out the safety catch with a sideways motion of the mandrel and removing it (Fig. 10).

Fig. 10

By lightly tapping a mandrel dia. 5 mm, drive the bolt head carrier approx. 10 mm forwards until the firing pin and the compression spring (18) can be removed (Fig. 11).

4.3.2 Checking the individual components

Having completed cleaning, and before incorporating new individual components and reassembling the slide, all parts are to be examined for impact marks (distortion), the formation of burrs, heavily worn positions and for crack formation. If serious faults are detected, then the parts concerned must be replaced.

The following components are to be subjected to special examination: Slide (1)

- Check for firm seating of the front sight (2) and the rear sight. A loose front sight blade must be replaced with a new one. If necessary, re-rivet the rear sight on the hollow rivets (visible from within).

- The slide must be carefully examined for any cracks - above all, on the side surfaces in the region of the locking system and around the ejection port.

- Brazed insert and stop pieces in the slide body must be examined for tight fit.

- The notch must not show any signs of wear or other damage.

- Guide rail surfaces must remain straight. The dimension between the rails must not exceed 17.6 mm (paying due regard to the sliding action on the receiver).

Safety catch (3)

The retainer edge for the firing pin and the edge of the notch depression (safety action too smooth) must not display any signs of excessive wear.
