Actually man, there are 6 inch figures that come with perfect in scale weapons, grenades, flak vests and even rubber holster belts and Berets.

Check any dollar store except dollarama for them, and usually a buck or two carries them as well.
If you can't find them and are still really hard up for an UZI, I'm pretty sure that I can hook you up. I picked up a bunch of those figures to equip my Ultimate Muscle army. ;-)
