I have not shot mine yet. I just thoroughly took it apart to clean all the dirt and grease out. There was alot of it. I have done a bunch of dry fire with it and it feeds and ejects fine. I have tried to make it malfunction by handling it weakly and odd manipulations hoping to get some thing to go wrong but nothing did. I can't see why it won't work. Also this gun is a beast, its the heaviest 9mm I have handled. The jericho was a dream gun of mine so these was perfect for me.
Buying extra mags was an hassle. It does not take just any CZ75 magazine. I bought the mecgar CZ75 mag with the blue follower. That one fits. The basic CZ75 mag would not seat.
I bought mine from G4C. I politely ask to see a picture of an example condition because the ones for sale locally were worn to the point of discoloration for the same price.
Goes great with the Israeli police baton
