My 2 cents. I have owned a CZ75B and found that it was not the most reliable pistol, failures to feed mostly. Changing the springs helped, but did not totally eliminate the problem. My son had a CZ85, basically the same gun, similar experience. I know there are legions of CZ fans out there, but my experience has been negative, also I did not like the fact that on the SA trigger pull the hammer is slightly cocked before release.
My experience with 3 Hi-Powers (one Argentine FM, one FN and one Browning) and many thousands of shots is different. There was one failure to feed with the FM and that was on the gun's second shot. The trigger pull is not the best in the world, but does improve with use and if you want you can remove the magazine safety for further improvement. The Mark 3 HP also feeds JHP ammo reliability.
I still have my HPs and consider them amongst the best firearms ever made.
