The rotation of the revolver in the inspection window is off to the far right, rather then centered, leads to a rotation of the weapon off screen (unlike other weapons - simply over looked)
The ability to load more rounds into a half empty revolver is so far impossible for me to figure out. Upon right clicking the weapon to search for a unload/eject option, only inspect pops up. The ability to right click, and load rounds is not there, and when you drag the rounds to the weapon system, it says its already full (which I know its not I just fired to rounds. What type of idiot walks around with only 4 rounds in his weapon!? :D)
