***[Function Inspection]{.underline}***

Trigger and Hammer Mechanism

1\. Decocking Lever

Clear the pistol.

Cock the hammer.

Place moderate pressure on the back of the hammer to ensure positive
sear engagement with the hammer.

Thumb down the decocking lever and check that the trigger returns to the
double action position.

Check that the hammer has come to rest in the safety intercept notch
before reaching the extreme dropped position.

2\. Double action function

With hammer decocked, pull the trigger.

Check that the hammer moves to the rear, drops forcefully and rebounds
to the safety intercept notch after striking the firing pin.

3\. Interruption of trigger function or disconnector operation

With hammer forward and the trigger retained to the rear, pull the slide
to the rear and release it.

Check that the hammer is retained in the cocked position (trigger
remains pulled).

4\. Single-action function

Release the trigger.

Check that the trigger bar engages the safety lever once more and, that
upon pulling the trigger again, the hammer is released.

B. Recoil Spring

Check the force of the recoil spring and smooth cycling of the slide.

Carry out the loading movement and check that the slide/barrel group
springs forward smartly and locks. Repeat once.

C. Magazine

Check the condition of the magazine tube, the lips and the floorplate.

Check for correct interlocking of the floorplate and insert.

Check for smooth movement and springing of the magazine follower.

Check for ease of insertion of the magazine into the frame and positive
locking.

Check for free in and out movement of the magazine catch.

With an empty magazine in place, pull the slide to the rear and release
it - the slide must be arrested in the rear position by the slide catch
lever.

D. Slide Catch Lever

Thumb down the slide catch lever and check that the slide is released
and forcefully springs forward.

Thumb down the decocking lever.
