No, not for reloading. Just factory ammo.
the reliability of 147 grain ammo as it relates to the regular CZ 75B.
MOST (I suppose not technically all) of the all-metal CZ-75 and variants have the same chamber cut, more or less the same fire control, and internal dimensions relevant to your question. No reason to isolate the question to a forum for one specific gun.
As long as we're here, though...
I load my own, and pretty much the only factory ammo I buy is for defense. The only 147gr factory ammo I have shot in my CZ pistols is Winchester PDX1, which was great. It's also what the FBI uses, or at least used to use, if that would make you feel more comfortable. It's great ammo. I am pretty sure others have used Federal HST 147 without problem, and that is fantastic defense ammo, as well.
If this is for self-defense, I would look no further than one of those two if you're set on 147gr, and there's good reason to use 147gr for defense, so I wouldn't steer you away from 147gr. It's not what I use, but if I didn't use what I use, I'd be using one of those two 147gr cartridges mentioned above.
If this isn't for self-defense, I wouldn't spend the extra money on 147gr. You're not getting your money's worth for any type of shooting other than defense with 147. Go with 124gr.
