CZ 75 Extended ambidextrous safety LHS only or single side.
Extra wide serrated paddle, swept back and down. Far easier to activate the safety, even for smaller hands.
The safety is applied with a rocking motion with the ball of the thumb, not by lifting underneath.
Fits all CZ 75 ambidextrous safety guns. If you wish this can also be fitted to non ambidextrous guns, but the shaft on the safety will need to be cut shorter on the RHS of the gun.
