Receiver

- Undo the moulded grip and wash out the receiver with paraffin, wipe dry and lightly oil.

- Lightly smear both guide grooves for the slide with gun grease.

2.3.5 Magazine

- Where contamination is heavy, strip the magazine (see Section 3.4) and wash out with paraffin, wipe dry and lightly oil the individual components.

3 Stripping and reassembling the pistol 3.1 General

The pistol is stripped for cleaning. If several pistols are being cleaned simultaneously in the same place, then care must be taken to ensure that the parts are not inadvertantly interchanged.

Before stripping the pistol, the safety catch must be applied and the weapon examined to prove that the magazine Is empty and that there is no round left in the chamber.

No tools are required for stripping or reassembling the pistol. The use of force is absolutely prohibited.

3.2 Stripping the pistol

Remove the magazine (Fig. 2).

Take off the slide by pressing the barrel clamp in the trigger guard forwards (Fig. 3). - Push the slide forwards to the stop and lift it off upwards.

- Remove the barrel by pushing it forwards against the pressure of the spring until it can be lifted rearwards and upwards out of the slide (Fig. 4).

To extract the bolt head, use one shank end of the barrel extension to press down between the bolt head and the slide onto the locking catch, until the bolt head springs forward (Fig. 5).

- Remove the bolt head from the slide.

It is not necessary to strip the pistol any further for major cleaning.

3.3 Reassembling the pistol

When inserting the bolt head, position it with its rectangular opening over the locking piece (extractor to ejection port) and, as when extracting the bolt head, press down the locking catch with one shank of the barrel extension, at the same time sliding the bolt head further back until it engages.

Push the barrel complete with recoil spring (larger diameter end of the spring to the front) at an angle through the barrel hole in the slide against the pressure of the spring (Fig. 6). Then position it fully into the slide, allowing it to move back until the locking rollers engage.

Mount the slide onto the receiver so that the front guide lugs can engage in the corresponding notches in the receiver body. Press the slide down onto the top of the receiver, draw it to the rear and then allow it to travel rapidly forward (Fig. 7). Uncock the pistol, and insert the magazine.

- With the aid of a drift, press down the lug in the floor plate of the magazine and slide the released plate off (Fig. 8).

- Remove the spring locating piece, follower spring and follower from the magazine housing (parts are under spring pressure).

The magazine is reassembled in the reverse order.

3.5 Faults, causes, rectification

When a stoppage occurs the pistol must be treated as if it is still loaded until conclusively proven otherwise. The points listed below do not purport to cover all possible faults. Similarly, the listed causes must not be regarded as exhaustive.

Fault

Cause

Rectification

Round fails to fire a) Ammunition fault (misfire)

Remain in the aiming position, squeeze the trigger again and, if round again fails to fire, apply safety catch, cock, examine cartridge, uncock and continue firing

Next round also misfires b) Firing pin broken c) Weak firing pin spring d) Firing pin jams or is distorted

Unload and return to the armoury for repair

(2) Pistol fails to open after a shot is fired

Cartridge jammed in chamber because round distorted or chamber dirty

Unload, drawing back the slide to eject empty cartridge; clean weapon if dirty

(3) Cartridge remains jammed between barrel and slide after firing a) Slide rearward travel limited, restricted movement, has not reached ejector b) Extractor, extractor spring or ejector damaged c) Weak firing charge providing insufficient recoil action

Unload, draw back slide and remove cartridge. Check for smooth running, clean if dirty

Return to armoury for repair

Use other ammunition

(4) Cartridges are not ejected_

Ejector distorted or broken

Return to armoury for repair

(5) Round is not fully

a) Chamber dirty

Unload! Clean

chambered, fails to

b) Round distorted

Discard round

lock

c) Guide rails and grooves dirty

Clean, lubricate

d) Guide rails and grooves damaged

Return to armoury for repair

e) Recoil spring for barrel weak

Renew recoil spring

or damaged

f) Locking rollers jammed

Fit a new bolt head

g) Locking catch damaged

Renew the locking catch

(6) Rounds are not fed

a) Magazine dirty b) Follower spring weak c) Magazine distorted d) Magazine lips bent

Unload! Clean

Replace with serviceable magazine, return other for repair

(7) Slide fails to remain a) Follower spring weak open after firing last b) Catch damaged shot

Unload! Exchange magazine Return to armoury for repair

(8) Slide fails to travel forward

Recoil spring weak or broken

Return to armoury for repair

(9) Catch fails to disengage

Catch damaged Cocking lever damaged

Return to armoury for repair

(10) Weapon cannot be cocked with cocking lever

Elbow lever broken

Unloadl Return to armoury for repair

(11) Pistol cannot be fired with hammer cocked

Pull-bar spring broken or disengaged

Unloadl Return to armoury for repair

(12) Pistol gives consistently poor shooting results

Front sight displaced

Return to armoury for adjustment

(13) Magazine jammed in magazine well

a) Magazine distorted b) Magazine catch faulty

Exchange magazine and return to armoury for repair

Return pistol to armoury for repair

3.6 Checks

Before returning a pistol to the armoury for repair, the following points must be checked:

(1) Cleanliness

(2) Examine front, rear sights and grip for firm attachment

(3) Examine the subassemblies for deposits of dirt, for damage and for function

(4) Examine the complete pistol for accumulations of dirt, for damage and for dents

(5) Check functioning of the fully assembled pistol

(6) Check functioning and condition of the magazine

3.6.1 Slide (Exploded diagram 1) Bolt head

- The extractor must lift freely and return to its initial position.

- The locking rollers must move freely when the bolt is shaken.

Bolt head carrier

- The locking catch (16) must move freely when pressed down.

- It must be possible to push the pressure pin (13) down to the stop and for it to return under spring pressure.

- The catch bolt (9) must be adjusted by moving the set screw (11) so as to allow unrestricted engagement and changeover of the safety catch.
