I have a CZ 97B, a P-O1 and a Kadet. I replaced the guide springs with SS.
Interesting, someone found that a brass door hinge pin worked.
But the plastic guide rods worked fine and make it easier to re-assemble after cleaning.
I replaced the recoil spring with a stiffer Wolff spring on the bigger gun.
Aesthetics: if you replace the grips, look at CZ walnut at the CZ Store online. Thin aluminum CZ grips for the 97.
I like Sellier and Bellot ammo, otherwise, any good American stuff, FMJ for the big gun.
Guide springs= guide rods
Get back wuick if u have questions. I’m almost asleep.
I am going to use the rubber grips for now. They fit my hand Very nicely and I like the sights, I might want a light gathering sight for the front.
