300 or less on any straight shooting, un-beat cz-75b is an excellent deal!
The 40B only came with 10 round mags, but the 12 round MecGar mags for the CZ-75 work great. The only difference is the base plate.
It wouldn't fit. It'll work on a 45 platform though. People have been wishing for a 97 in 10mm for years.CZ should make a 40B in 10mm....
