How do I Adjust the Over travel Screw on CZ Pistols

The over travel screw should not be set too fine.
The TEST WITH NO BULLETS IN THE GUN.

Pull the trigger all the way to the rear as if firing and hold tight at the back of the trigger guard.
Rock the hammer back and forth and see and feel if the sear is hitting the hammer hooks...
If there is any contact at all, the Over travel screw needs backing out more, ie away from the frame, then test again.
There is no specific distance for the over travel screw.
This the same test for 1911, if the sear and hammer contact, then sear / hammer hook DAMAGE WILL OCCUR.

Over travel screw on ALL firearms not just CZ's do move. This test should be carried out if there seem to be any issues.
If we get guns returned this is the first test we do to ascertain if the over travel screw has being badly adjusted and that has caused the damage.

This is NOT a warranty defect....   It is a badly adjusted screw.
