7.5 Verification of functions
Note:
• Verification of functions must be conducted on
the assembled pistol:
– to identify causes of malfunction,
– after completion of repairs,
– and after each cleaning and assembly of
the pistol.
Procedure:
1. Make sure that the magazine is removed and
the pistol unloaded (see Section 5.8).
2. Check the elasticity of the recoil spring 3 and
the smoothness of the slide 4 (no jamming).
– Draw back slide to the stop and allow it to fly
forward.
– Check that slide is impelled forward with
sufficient energy and that it engages.
– Repeat the verification test.
3. Check the double-action trigger (DA).
– With hammer 29 decocked, pull trigger 20
through.
– Check that hammer cocks and that at the
end of trigger travel, it strikes firmly forward
and comes to rest in the safety intercept
notch.
4. Check trigger travel and trigger interruption.
– With hammer 29 decocked and trigger 20
pulled through, draw back slide 4 to the stop
and release it.
– Check that hammer 29 is restrained in its
cocked position (trigger remains pulled
through)
(With DAO/DAK pistols, the decocked
hammer 29C/D must register in the safety
intercept notch).
5. Check simple trigger function (SA).
(Not applicable to DAO/DAK pistols).
– Release trigger.
– Check that trigger bar 22 re-engages and
whether hammer 29 drops when the trigger
is pulled again.
6. Check function of decocking lever 40 and
safety intercept notch on hammer 29.
– Cock hammer 29 and decock it with
decocking lever 40 without touching trigger
20 (not applicable to DAO/DAK pistols).
– Check that hammer 29 is arrested in the
safety intercept notch before reaching its
forward end position and trigger is guided to
the rest position.
7. Check slide catch lever 18.
– Insert empty magazine, draw back slide 4 to
the stop and release it.
– Check that slide remains caught in its
rearmost position.
– Press slide catch lever down.
– Check that slide is released and impelled
forward with sufficient energy.
– Press decocking lever 40 down
(not applicable to DAO/DAK pistols).
– Remove magazine.
8. Inspect magazine.
– Check condition of the magazine tube 51 for
signs of damage or dirt (lips and floor plate).
– Check that the magazine floor plate 54 is
properly secured.
– Check free movement and spring action of
feeder 53.
– Check smooth insertion of magazine into
frame 15.
– Check magazine catch 43 for clean
engagement and release.
