Spring Rate of the CZ 75 TS

[Hidef1080]

New guy here with some basic questions:
Does anyone know what the spring rate is for a stock CZ 75 Tactical Sports .40 cal?
Also, if I wanted to go with a “custom” spring [heavier than stock] where would a be able to order one?
I've checked Wolf Springs and both CZ-USA and CZ Custom but I did not see any recoil springs for the Tactical Sports.

Would I even need a heavy spring if I shoot 165 at 1050fps?

My fear is cracking the frame.
When I pull the slide back it just feels “light” to me.
I currently own a Mark III and Glock 22 and in the past I've had a 1911, CZ 75B, 645 and 1006 and my CZ TS feels the lightest of all of those. Not the Mark III needless to say...

Any input would be appreciated.

I don't have the answer to your question, but on the other hand, I've never heard of frames cracking on the Tactical Sport.

The downside of a stronger spring is that when the slide returns, it will do so with greater force, with all that force focused on the slide stop. You may be protecting one part of the gun and putting a different part at risk. And since the slide stop is attached tbrough the frame, it's taking THAT force, too.

How far do your spent shells fly? If they're landing nearby, you may not have cause for concern.

(Contact Mike Eagleshield at CZ-USA about the proper recoil spring weight.)
