Bob,

27" drillings in 16 gauge are of a weight and proportion that they handle very much likes quality double barrel shotgun. If perceived weight, swing, and speed of acquisition are important to you, the aforementioned drilling will come close.

On the other hand, usually 12 gauge drillings are 24" barreled and they don't feel at all like shotguns. They feel like boat oars to me. It's an awkward handling sensation if you shoot shotguns often for a point of reference.
