By your logic, anyone who doesn't agree with you is wrong and is making excuses. These are valid counter arguments to what you are saying. You want everyone to see things from your point of view but don't want to do the same when some offers a different point kid. The shotgun has barely changed design in like 200 years. The ammunition and system used to deliver the shot are most likely different. You're assuming these guns use a standard black powder ignition system. Which is stupid to assume. Since they don't require the same things modern convential fireearms need to fire they can look and fire whatever way the person who created it want it to. If they want it to look like a revolver they can. It doesn't impact the actual functionality or mechanics of the gun. You're trying to compare apples and oranges seeing as most of the guns in game, even the hand cannons and such, simply cannot exist because the ammunition they use hasn't been created or doesn't exist. And seeing as we can't tell what the future holds we don't know if something like this would be created. Your argument is null and void.
