Riana,
I am opposed to 'guns' for fun/sport.
Use a bow & arrow, that takes strength & skill.
I see no need for guns except to hunt, if you intend to eat what you kill.
That said, there is no need for clips with more than 8-10 bullets. If it takes a pro seconds to refill, so what, most murderers will at least have to take those seconds which may be enough time for someone to stop them.

DO SOMETHING!
