Dismantling for cleaning

Cleaning

The person to whom the pistol has been issued is responsible for its operational readiness at all times.

5.1. Cleaning the weapon

5.1.1. General

The weapon must be stored in a dry location. Humidity and rapid temperature changes are detrimental and encourage corrosion.

If a weapon is not to be used for some time then it must be well greased, particularly the bore of the barrel and the blank parts.

The pistol should be cleaned immediately after use. If this is not possible then at least the bore must be greased using the wire brush.

5.1.2. Cleaning procedure Sequence of operations:

1) Dismantle the pistol

2) Clean all parts with a dry cloth (after the weapon has been fired, the bore of the barrel must be cleaned also)

3) Lubricate in accordance with the specifications

4) Assembly the weapon

5) Carry out functions check

6) Carry out final inspection

5.1.3. Cleaning the barrel

Sequence of operations:

1) To remove all traces of powder residues, push through a greased wire brush at least ten times, from the chamber end

2) Clean the barrel using a jag wrapped with a strip of cotton cloth

3) Check the barrel for cleanliness

4) Lubricate the barrel lightly with a grease-covered brush

5.2. Lubrication specifications

6. Weapon functions

6.1. Function of the trigger assembly

6.1.1. Weapon loaded, hammer decocked

With the weapon loaded and the hammer decocked, a shot can be fired with the double-action trigger.

By squeezing the trigger (20), the trigger bar (22) is drawn forward and cocks the hammer (29). The trigger bar (22) also operates the safety lever (28) to lift the safety lock (13). The safety lever (28) draws the sear (24) out of register with the hammer (29) whilst the safety lock (13) liberates the firing pin (11).

Continued movement of the trigger (20) causes the trigger bar (22) to release the hammer (29) which strikes the firing pin (11) and detonates the cartridge primer.

6.1.2. Automatic interruption of trigger function

Upon firing

After firing, the blowback reaction thrusts the slide (4) rearward. The slide (4) depresses the trigger bar (22), disconnecting it from the safety lever (28) and hence releasing the sear (24). The sear, under pressure of its spring (25), returns to its initial position and arrests the hammer (29).

In order to fire the next shot the trigger (20) must be released to allow the trigger bar (22) and safety lever (28) to engage again.

If the trigger (20) is squeezed once more while in the final third of its stroke, then the trigger bar (22) actuates the safety lever (28) which lifts the safety lock (13) to liberate the firing pin (11) and also withdraws the sear (24) to release the hammer (29).

Incomplete locking

If the slide (4) does not return to the full battery position due to a weapon, magazine or ammunition malfunction, connection between the firing pin lock and safety lever (28) is not made. Therefore, de-activation of the safety lock (13) is automatically prevented.

In this disconnected state, the slide (4) also cams down the trigger bar (22) and effectively interrupts subsequent trigger functions.

6.1.3. Decockinq lever and hammer safety notch

The decocking lever (40) allows the cocked hammer (29) to be safely lowered into the safety intercept notch. In this condition the weapon can be carried with a cartridge in the chamber, ready for immediate use.

The safety intercept notch is the rest position of the hammer (29). It also becomes effective in case of inadvertent hammer tripping when thumbcocking the weapon.

Thumbing down the decocking lever (40) takes the sear (24) out of register with the full-cock hammer notch. The hammer (29) drops forward, returning the decocking lever (40) to its original position, and is arrested by the sear (24) engaging In the safety Intercept notch.

During this operation the safety lever (28) remains in its rest position and does not lift the safety lock (13). Hence, during and after decocking, the firing pin (11) remains constantly locked. By this means, even dropping the weapon cannot cause inadvertent discharge of a cartridge.

In order to achieve optimum safety the firing pin (11) is locked in the slide by the safety lock (13). Immediate first-shot potential Is ensured by the trigger action. During which the trigger bar (22) pivots the safety lever (28) to raise the safety lock (13) (thus liberating the firing pin) immediately prior to tripping the hammer (29).

6.1.5. Weapon loaded, hammer cocked

By squeezing the trigger (single-action) (20) the trigger bar (22) is drawn forward.

The trigger bar (22) pivots the safety lever (28) which lifts the safety lock (13) to liberate the firing pin (11) and also moves the sear (24) to trip the hammer (29).

6.2. Unlocking, recoil movement and locking

At the Instant of firing, the weapon is locked, i.e. the barrel (1) is seated on the locking insert (17) in the frame (15) and is locked with the slide (4).

Blowback reaction thrusts the barrel/slide system rearward against the recoil spring (3). After recoiling about 3 mm the barrel (1)

is forced down and arrested by the locking insert (17).

The pistol is unlocked.

The slide (4) continues rearward, cocks the hammer(29), extracts and ejects the spent case and compresses the recoil spring (3) further.

The recoil movement is arrested by the slide stop in the frame.

The compressed recoil spring (3) thrusts the slide (4) forward, stripping a round from the magazine (51) and chambering it on the way to the battery position.

Just before reaching the forward end position, the slide (4) again locks up with the barrel (1).

Barrel unlocked b) Ejection port c) Guide surfaces

Arresting mechanism (slide catch, lever)

After firing of the last shot, the slide (4) is arrested in the open position.

The feeder (53) of the empty magazine (51) raises the slide catch lever (18) which engages the arresting notch of the slide (4) and prevents its further movement. Upon thumbing down the slide catch lever (18) the moving parts are released and spring forward.
