I would have to agree that the slide going forward on a full magazine was one of the selling points for me. It's a defense gun an does little good to have a gun with full mag and slide back. I thought CZ designed it that way, maybe not. Not sure why you wouldn't want it to do this???
Simple, because it's not a reliable method to load the pistol with...Now I know there's going to be a bunch of people who will disagree with me,claiming they can do it each and every time. That's ok on a square range, but what happens when it's not, and someone is shooting at you? Once at a class I took, we were doing reload drills, from low-ready shoot two rnds at target, reload and shoot two more, guy beside me was shooting a M&P, shot his first two rounds, slammed a mag in hard in a effort to auto forward, the pistol did'nt, instead of pulling the slide release, or pulling the slide back and releasing, he kept slamming the bottom of the mag, until the instructor stopped him, and used this as a example as to why relying on auto forwarding to work was a bad idea. Besides, show me a decent instructor who reccommends this as a viable method. Anyone who does, is someone who I would'nt take training from.
