I have a CZ semi-auto shotgun that I purchased used 3 years ago. I have never had a problem until this year. I will take the first shot, the second round will cycle and load, but will not fire. I can pop it out and put in a new round and it will shoot it, but not the following rounds. Prior to taking it to a gunsmith, which are few and far between around here, I wanted to find out if anybody had run into the same issue and what they did to fix it. Thanks.
