I have been looking into a P-64 Radom for pocket carry, but I am also fond of the CZ's, having owned a good many of them. Does anyone find the CZ50/70 suitable for pocket carry? I would need to pocket carry in slacks with a button up. Does anyone do this?

Pretty heavy and large for pocket carry, I'd recommend against it.

I pocket carried  a vz. 70 for several years before I upgraded (with less weight, better round) with an XDs the middle of last year. It works and I didn't find it uncomfortable. Worked in jeans, carpenter type pants, slacks, etc.

CZ-70 is a well built pistol with many features not found on most imported/surplus sidearms. However, the two i had back in the day suffered from the same two problems - the caliber, .32 ACP, not the most potent of rounds, and the LONGEST trigger pull I'd seen from anything except an Astra A-80. If the trigger could have been improved, I would still own one today. Makarov.com used to sell a rebuild hit for it, but they went off lines a decade or so ago.
