Dumb Question...? More is better right? I've been wanting to add a shotshell carrier to my 870 and I can't decide if I want to get a 4 or 6 shell version. I keep thinking that getting the 4 would be a mistake because why not carry 6. The only advantage I can see with the 4 is that it is more compact and I don't know if that is a real advantage or not. Can anyone offer an opinion based on their actual experience?

The purpose of this shotgun is primarily defense with some fun at the range. In the future I would like to take a shotgun class.

Thanks
