Compression spring

- The uncompressed compression spring must have a length of at least 7.00 mm.

Firing pin (17)

- The hooked rear end of the firing pin (17) must be free from wear or damage.

- The tip of the firing pin must be free from any signs of erosion.

Compression spring for firing pin (18)

The firing pin compression spring must be undistorted and have a minimum length of 18.5 mm when uncompressed.


Damage to the firing pin is frequently caused by incorrect dry training and frequent dry snapping with the pistol put at safe.


Dry firing practice is only to be carried out with the safety catch released!

- Using the copper mandrel, drive the bolt head carrier to the rear until the drill holes in the bolt head carrier and those in the slide are aligned.

- insert the safety catch, push the firing pin fully forward ensuring that the nose on the end of the firing pin is visible (Fig. 16).

4.3.3 Reassembling the slide

The bolt head carrier is reassembled in the reverse order of stripping.

- Insert the bolt head carrier into the slide, drive it slightly to the rear with a copper mandrel dia. 15 mm, and introduce the firing pin complete with compression spring (Fig. 15).

- Press the safety catch fully home, and check its action by rotating it into the „Safe" and „Fire" positions.

4.4.1 Stripping the receiver

- Strip the pistol as described in Section 3.2.

Undo the lenshead countersunk screws on the moulded grip and then remove the grip from the receiver.


The moulded grip can only be removed when the pistol is not cocked.

Remove the magazine catch (25) by pressing out the cylindrical pin (6) (Fig. 18) and removing the compression spring (24).

Fig. 18

- Undo the countersunk screws (29) (Fig. 19) and then take off the left-hand bearing plate (28) followed by the right-hand bearing plate (31).

- Lift off the elbow spring (32), and remove angle lever (26), cocking lever (27) and the intermediate lever (30) (Fig. 20).

Fig. 20

- Draw the trigger back approx. 10 mm.

- Press out the hammer axle (23) (Fig. 21) and then remove the hammer (20), disconnector (22) and the indicator pin (21).

- Drive out cylindrical pin (6) (Fig. 22), remove the safety latch (16) and the catch lever (17).

Fig. 22 20

- Disengage the pull bar spring (33) from the pull bar (18) (Fig. 23).

Fig. 23

- Release the catch spring (3) from the pin and disengage from the catch (2) (Fig. 24), then remove the catch together with the spring. (Do not distort the spring).

Fig. 24

- Drive out cylindrical pin (6) for the trigger (Fig. 25), remove the trigger spring (5), disconnect the pull bar (18) and the trigger bar (19) from the trigger (4) and remove.

Drive out cylindrical pin (6) for the barrel clamp (Fig. 26), remove the barrel clamp (7) and compression spring (8).

Fig. 27

Fig. 26

- Unscrew the threaded insert (15) and the lens head countersunk screw (11) applying counter torque to the insert (15), and remove (Fig. 27).

- Remove support (14), buffer housing (13) and the elastic buffer (12).

- Unscrew and remove oval head countersunk screw (11) from the trigger guard (10).

- Lift the trigger guard (10) on both sides with a screwdriver (once on the left-hand side and twice on the right), then unlatch from the receiver (1) and draw off forwards (Fig. 28).

- Remove insert piece (9) downwards and the trigger (4) upwards.

Before incorporating new individual components and reassembling the receiver, and after having cleaned and examined the bores for perfect condition, carry out the following checks:

Examine the receiver (1) for cracks; the guide grooves must be correctly aligned and devoid of any distortion.

The ejector must protrude above the upper edge of the receiver by between 2.9 mm and 3.1 mm.

- The buffer housing (13) must be examined for crack formation and bulging.

- The elastic buffer (12) must not be squashed.

- The functional hook on the pull bar (18) must not have excessively rounded-off points.

- The catches on the intermediate lever (30), hammer (20), and catch lever (17) must not show any signs of heavy wear or damage.

- The compression spring for the shank must have an uncompressed length of 59.5 mm.

4.4.3 Reassembling the receiver

- Insert the catch (2) into the receiver (1) and push it up through its full travel (Fig. 29).

With its short leg pointing upwards, introduce the longer leg of the catch spring (3) into the drill hole provided in the fitted catch (Fig. 30).

Fig Pph Kutz Pistol

- Press the eye of the catch spring over the permanently incorporated pin on the left-hand side of the receiver, pulling the shorter end of the spring upwards until the spring end locates against the fixed stop abutment. This action places the catch spring under tension so that it is pressed downwards. Insert the trigger (4) from above (Fig. 31).

- Introduce the insert piece (9) with its semi-circular surface downwards so that both lugs are towards the right-hand side of the receiver, looking towards the muzzle end (Fig. 32).

Fig. 32

- Mount the trigger guard (10) on the receiver pushing it up and pressing it until the trigger guard engages on both sides in the receiver

Fig. 34

Position the trigger spring (5) in the trigger so that the longer end of the spring points towards the muzzle end. Retain the trigger and the trigger spring in the receiver with the assembly pin (Fig. 34), follow up with cylindrical pin (6) until it fits flush with both sides of the receiver.
