Rossmore combat shotgun

This weapon is as video gamey as they come! My oldest brother was an ordinance specialist in the Army, and a hunter and shooter. I learned more than I ever really needed to know about firearms while we were roommates. So... anyone else spot the elements that make this weapons a fantasy? It's an over and under double barrel that loads from both a tubular magazine under the barrels AND a box magazine under the receiver (they normally load by "breaking" the barrels down and inserting shells one at a time)! But wait! It also has ejection ports on both sides of the receiver (for ambidextrous reloading of single shells?). In game, it ejected the shells across your face, they all did, because that looks cool. Oh, and it's effective range was about 6". Because. Shotgun.

All of that aside, it's a nice looking asset, and was fun in game if you were a sneaky bastard.
