I have a CZ-52 in both 7.62 and 9mm - I like them, but still would like a TT of some sort.
I don't dry fire them (never understood dry-firing - that's what snap-caps are for if one really must), the roller mechanisms on both are in good shape, have no issues with the magazine releases, and they're good-looking pistols. And I just like Czech guns. I put some wood grips on my 7.62 -
