Shot them side by side today with same ammo and mags. Both shot well or I did but the C-100 seemed to have slightly more felt recoil.
I believe this is due to it having a aluminum frame while the CZ has a steel one.
I have not shot anything in 3 weeks due to some heck/back/shoulder pain so today was a good day. I was not that bad for having not shot lately.
The Canik has CZ compact rubber grips on it, I like them better than the Canik plastic grips.
I also replaced my C-100 recoil spring with the CZ compact spring, worked like it was made for it.
I think I will order 2 CZ compact recoil springs, one the Canik and one for the CZ, both have quite a few rounds down range.
The barrel on the CZ has turned a gray color while the finish on the Canik has worn off in a few areas but both still get the job done.
Have a Nice Day!
