I agree with you 100% that a full stocked gun is much quicker for skeet or 99% of defensive shooting. I also believe that for a general purpose defensive arm, you should definitely go with a full stock gun (that is what I got). But in certain, very specialized conditions, a PGO shotgun can be used effectively. Especially if one is willing to train with it, which is 90% of the problem with any type of firearm. Examples of its usfulness that I can think of is shooting from inside a vehicle, in very tight foilage, as a door buster, inside a ship, plinking, etc. In certain areas in Hawaii, pig hunters use PGO shotguns because the foilage is so tight. While I believe that its role is extremely limited and specialized, in those roles it can be extremely effective. I believe it to be like a rifled 12ga slug gun w/ a magnified optic, used in its rightful role, very effective.
