This subject is more controversial than the old .30-06 vs the .270 Winchester argument. Everybody seems to have different opinions about what makes or breaks the ideal fighting shotgun. Most of my shooting experience has been done at the trap and skeet range. Even when shooting trap and skeet aimed fire is still more effective than sustained fire. You just have to lead ahead of your target if it's moving. Forget about that "Aim in the general direction" nonsense. I also think pistol gripped shotguns are for mall ninja's and are a complete waste of time. Some of the familiarization and fundamentals you use in shotgun sports can be applied to the HD shotgun situation. I'm not going to say what type of action is best but I think if you do alot of skeet and trap shooting you should use a short barreled version of the gun your used to for Home defense.
