Personally, i dont care if a gun is theoretical correct or not.
A game is meant to be fiction, so why would it hurt someone if a weapon is fiction?
Look at Painkiller...those weapons didnt make any sense.
Unreal tournament...the same about that game.
But...you are right BIG viking games...
Even though this isnt possible in real life, in fiction it is.
But it still doesnt make sense if i could fire with a small pistol.
Around the ? bullets in a few seconds...That would mean if i just pull the trigger...
The gun would already be empty.
So maybe a stock for the bullets. A big one of course.
But still...like the idea.
