I just took out my CZ82 for the first time and encountered a problem. After firing the last round, the slide locks in place like it is suppose to. When I release the magazine the slide goes forward, just like I pushed down on the slide release lever. Could this be a problem with the magazines? The reason I ask is that the two that were supplied were not the greatest. One sticks in the magazine well and I had to solder the magazine plate to the magazine( the metal tit(?), was broken off).
