The terms Pistol Grip and Straight stock are confusing, a cultural clash perhaps?
Shotgunners refer to a full stock with a pistol grip behind the trigger as a pistol grip stock. A straight (or english) stock has no pistol grip and is normally found on lightweight side by side guns designed for bird hunting.
A stock with only a pistol grip and lacking the ability to be shouldered should not be called a pistol grip. Perhaps we should find another name for it?
I once shot a round of Sporting Clays with a young man who had a Benelli M3. He shot quite well and demonstrated the M3's ability to convert from an auto to a pump by turning a ring near the magazine cap. Seems to me that this would make a good combat shotgun, as the gun could be converted to a pump action if the auto failed to cycle.
