CZ Kadet with 9mm top end

[wizzegun]

I have a a CZ75 and a Kadet. The Kadet top works on the 75 frame but not vice versa. I put the 75 top on the kadet frame and it doesn't fire. I checked the primer and it's BARELY struck. OK...so I switch the hammer springs. Same thing. Anybody know what the difference would be or am I overlooking something? I would love to be able to run a 9mm top on the Kadet frame since I have a Crimson Trace on the Kadet.

Thanks

Do the kadet hammers weigh less than the standard cz hammers? Perhaps the firing pin return spring is too heavy for the kadet hammer to overcome? Also, do the kadets have firing pin blocks?
