I took 2 CZ75 mags with me last week and ran them at the range for testing purposes in my 07. They ran flawless with bolt hold open on last shot every time. No issues feeding or chambering 1st round when completely full. There is just a touch of looseness side to side, but I have other 9mm with more that use the correct mags made for them.
IMO these are fine for range or back up use during the Zombie Apocalis.
In fact I ordered 2 19 round and 2 17 round CZ75 mags on sale for less than 2 07 mags would cost.
I doubt the mag will cause wear to the mag catch as it is locked in completely and not made of soft metal.
These are my results and opinion......others may not agree.
Have a good un.
