Okay, got a .22 LR conversion, the Kadet II, for my CZ 75 compact. It will lock the slide back when I push in the magazine in, but if I'm just holding the grip (as if shooting) it won't lock the slide back. Is this a known problem? Is there a known solution? Do I need to call up CZ-USA? Haven't gotten a chance to shoot it yet, if that changes anything. Short post, but just a simple problem (I hope).
