I have handled a couple of the Famars four barreled guns. they were both 28-ga. They are a facinating piece of workmanship but not something that I would want to hunt with. As well made as a Famars gun is these just feel a bit to awkward in my hands. Here in NJ there is a three shell limit and simply not loading the fourth shell would not get you within the law either. The gun need to be unable to hold more than three shells. At the cost of a Famars gun it would be a very expansive novelty also.
