hmm... newb question... so 6 in the mag in a semi auto non restricted shotgun with one in the chamber allready is legal? i thought that it was 5, or is it a shotgun regulation? pretty sure that all the benelli m4's are 5+1, wheather they are the restricted or non restricted models
mobgma has it right. The mag capacity limit is for the largest shell the gun is chambered for. if you can only get 5 rounds of 3" in, but 6 rounds of 2.75" fit that is legal.
