Done in PMG 0.6.
Looks cool and really unique. Not sure how well it would shoot, though. The magazine placement would necessitate that you bend your wrist to fire, making it more difficult to control recoil.
Hm... I don't really know, how it would behave while firing (and since form over function is my motto, I don't really care ), but there are stocks on rifles that require you to bend your wrist (like the stock of the Walther WA2000 or the SL8 stock, and they don't seem to cause problems...
That's because a rifle is braced against the shoulder instead of held in the hand... but in any case, it still looks cool!
sweet man!! Bullpup pistols are the bomb!
