The guns made for 7.62X25 are large, heavy, and cumbersome. Not great qualities for CCW. The CZ, or correctly vz52 has the best safety of the guns chambered for this round, but is very large for the purpose. Finding quality, reliable SD ammo may also be a problem.
At the high velocity of the round, fmj would be out of the question due to inadequate expansion, and over penetration.
Finding an adequate concealable holster could be another challenge.
The CZ (vs) 52 is an interesting firearm with a unique and interesting mechanical action. Mine is a great shooter, and lots of fun. The 7.62X52 cartridge is equally interesting with it's bottle neck design, and high velocity. They just don't fit well in concealed carry.
