The straight or "English" stock makes for a quick pointing rifle. It was used in, and still is, English cut fowling pieces, shotguns, for upland hunting. It points faster from port arms, slightly. But, the difference is minuscule compared to a modern shotgun IMHO. The look is a might unique, though. If you look at traditional SxS shotguns, old ones or expensive new ones like the new Savage branded, Connecticut arms manufactured Fox, they'll usually sport a straight stock. It ain't the old Winchester lever guns that started it.
