So, I have read on here about people using single recoil springs in the early dual recoil spring Compact guns. People have recommended Cajun for a source of those springs. When I first contacted them they said it must be some sort of after market system because to their knowledge CZ never used such a set up in the 75 Compacts. When I pointed out that I bought the gun brand new and it is dated 1992, they said contact CZUSA. Now, I already know the answer from CZUSA, so what source for single recoil springs, and what # springs are you people using? Thanks for your help.
