U Shaped Pistols

I mean, why not?  The stuff of SciFi, but they are certainly doable.   Go one step further with the Rhino, and Jason Bourne, and the trend is toward optics for your pistol.

Picture something like this, but the bullets come out of the bottom side, and the top side is scope, maybe something ACOG like, with a longer eye relief.  To load, you shove a mag in from the top.  Recoil would be down, so it's steady on a rest and doesn't flip in from of your target when shooting offhand.

Crazy talk, and too weird to take off, but, you never know.  I can't think of any reason why the concept wouldn't work.  Of course that doesn't mean it would work.  It's a limitation here, between the ears, mebbe.
