as far as a real one, an H&K MP5 would be pretty neat. ive sometimes looked at the Century AP5 which is a good clone of it, but i dont need to be spending $1000+ on another gun, i already dont use the ones i have enough.
I really want a BT USW

It's like the 21st centuries answer to the ultra-compact close defense firearm. The optic mount is attached to the frame rather than the slide so it doesn't reciprocate which helps it retain it's zeroing and makes it easier to maintain your target. Plenty of room for accessories. And the whole thing folds up to not much larger than a full frame pistol. :italiankiss:
