My only experience with this type of platform was a Tanfoglio TZ-75. It felt very good in my hand, and fed everything I ever put into the magazine, FMJ, RNL, HP, JFP. Trouble was, it eventually started giving me light strikes, requiring a second pull on the trigger - major no-no in a defensive piece. Ammo made no diff, primers made no diff, it simply would not fire every time ! I've not yet had the opportunity to try a CZ, but heck, I'm only 70, there's time.
