OK, I didn't realize how much detail was put into guns in Ghost in the Shell SAC: http://www.imfdb.org/wiki/Ghost_in_the_Shell_Stand_Alone_Com...

I didn't even feel like it had much of a focus on gun fights, but apparently it's like a detailed firearms museum. They also have airsoft product placements... I'm not that surprised, some people probably bought the featured airsoft guns purely for display.

The "POKER FACE" episode from 2nd GIG is one that focuses quite a bit on guns, though not exclusively.

Masamune Shiro is somewhat of a gun nerd, it turns out.

I'm impressed how much detail they put in the animation and how much work they put into documenting this too.

What was the SAAAIIITTOOOOO HAND OVER THAT WEAPON! ?

Well, that was probably some fantastical hand held railgun.
