Riding Shotgun or more properly riding with a shotgun

Ok here is a picture of what a shotgun would have/should have looked like during the ACW and yes mainly Rebs carried them early in the war.  After that Union Cavalry arms were easy to come by.
So please cut down that silly full size TSSD shotgun  they got their Cavalrymen carrying.  LOL LOL Thanks.  I don't care for this man's hat but that is another rant.  And the fact TSSD and Paragon have poses with the reins in the wrong hand is also another rant. LOL LOL
