Just remember not to mount sights along the side on the slide.
I had a buddy that for some very very very stupid reason decided to mount red scope on the blowback bolt of his paintball gun. He's lucky he just got a black eye from it, but it always made me sad that anyone would be that stupid (I mean who puts a scope on a paintball gun anyway, they arn't that accurate to begin with).
I mean its bad enough when hunting season starts every year and all the new hunters walk around with black eyes for first week from getting to close the scopes on their rifles. Then again, I'm one of those silly people that stops and thinks about things for a whole two seconds before doing them.
As for the pistol whipping, is their anyway to make the pommel of the pistols shock like a taser does? I suddenly feel that this is a very needed modification/accessory.
