I have a CZ 50. My biggest complaint is that if I load more than 5 rounds in the magazine the gun will not chamber a round. It crashes into the feed ramp and jams. I have installed the Wolf extra power mag springs, bought two new mags, cut a slight radius on the front of the mags, and tried different ammo, all to no avail. It is a great little pistol, and very accurate with its fixed barrel, but mine is only a 5+1 for now. I'm not too upset because I only paid $100 for it at a local pawn shop, and it is very safe to carry since you can engage the safety even with the hammer down.
I got a cheap Ace IWB holster sized for most .32 autos that fits it like a glove, and place this into my back right pocket of my jeans for walking around the house or working outside. Great gun, just can't fully load the mags.
Also, does anyone know where to find a new recoil spring for these little guns? I would like to replace mine, but haven't found where to buy them.
