I don't currently have a shotgun but I used to have a Mossberg 500. I sold it to Jody Hudson for financial reasons not because I didn't like it. I absolutely love shooting shotguns and I've only waited this long because I was stuck on handguns for a while. Because I owned and liked the Mossberg I'm considering it but I'm leaning against it for two reasons (neither anything against the Mossy or a shotgun). First, I'd hate to buy something I already had and sold-seems like too much of a waste of money. Second, I generally like the Remington better. The biggest advantages for me of the Mossberg are that I'm already familiar with it and the safety is better positioned (both important for a HD gun).
So, to summarize my long winded reply, I already know I'll like shooting shotguns.
