How exactly would that mechanism function in a pistol? If the slide moves whenever a shot is taken so that the shell could be ejected, wouldn't it lead to both chambers being emptied at the same time? Unless the intent is that both bullets are fired at once, you'd be wasting unspent bullets. If they are both fired at once, I'd think the laser sight would be centered at the bottom to reduce the offsetting of the left hand chamber to where it is pointing. I realize I'm taking it a bit to seriously, but I'm just thinking out loud about things that could be changed to make it at least a bit more plausible.
