looks good, but um 12.7mm is a little...well, it's a lot big of a round for this lol, 12.7 is huge. a pistol this size takes maybe a 2.5 to a 4.5mm and that would be pushing it. just little details that you may want to make more realistic :) and it would never be automatic. 12.7 is for a .50cal machine gun.
