from my own experience yesterday... paintball in germany is not banned
although there are several limitations, due a paintball gun couts als an gun in the terms of the law (waffengesetz).
for example you are limited to 7,5 Joule maximum and semi only.
but it is still fun playing.
if you plan on playing in germany pm me for some hints.
about the question if it hurt less... simply don't get hit
