1) Field strip the Pistol, taking the Slide Assembly off of the Frame.
Remove the Barrel and Recoil Spring Guide Rod and Spring from the Slide.
Fully cock the Hammer on the Frame and run the Slide thru the Frame Slide Rails to check for free travel.
Remove the Slide from the Frame.
2) Mount the Barrel on top of the Frame Barrel supports and move the Barrel back and forth to check that the Barrel Underlug has enough clearance to move freely.
If not, then the sides of the Barrel Underlug may need sanding/polishing.
3) Check the Recoil Spring Guide Rod Frame Recess for obstructions.
4) Reassemble Pistol and check Slide Function.
IF none of the above has helped, either contact SAR USA and ship the Pistol to them for service, or seek out the services of a
competent local Gunsmith, familiar with the Cz75 design, and have him look at it.
I asked why it was so difficult when none of my CZs or other clones do this. He pointed to "Made in Turkey" roll mark on the frame.
Beware of the ignorant, for they too, roam the Earth.
