Call me odd, but really do see a practical use. Think of it mounted to the side of a pack frame for use in deep backwoods camping/hiking. User would have a side saddle with some heavy buck for predator defence, some light shot for food forraging, and some flares for "I am lost come find me" signals.
Nothing I would want to shoot often, but could be handy for a lightweight, handy survival gun.
As for a name, RMSG (Rocky Mountian Survival Gun)
Were you to do another, I would seriously consider buying it, even with the $200.00 tax.
