I voted for the DS only cause of its monster size and shape. But any big bore barrel looking you right in the eye can make you quiver. I think that seeing that big black hole or tunnel that will introduce you to the tunnel with a light at the end of it can make anyone shake in their pants. But then I doubt that anyone aside from those with death wishes, would be less than intimidated looking down a barrel of anything regardless of caliber, including .22's and all other mini cals.
