So, can you modify the CZ 75 "to look/act" like a CZ 85 and still be legal. I mean, the parts are the same except for the right side controls and the side of the holes in the frame. Well, there sear cage is different (right side safety sticks into the sear cage some) and the detent and spring that fits in the frame and pushes against the back of the safety.
It is possible to modify the CZ 75 to have the right side safety. Do you intend to do it? Or have it done? It won't be identical (inside) to the CZ 85 as the frame inside won't accommodate that detent and spring, but it will work. Mine does. Took a lot of measuring, remeasuring, a little file work, buying the right parts, a lot of stoning to get the safety to work with the new hammer I installed (I put a spur hammer in my CZ 75 Compact to make it look even more like a CZ 85. Been working great for several months now.
