Well there aren't any bears etc in Australia. About the only dangerous land animal in NZ has is the Kiwi.
There just isn't any practical need for weapons like these.
Totally different situation.
In all honesty, i think half the problem is pro gun groups like the NRA, pushing their agenda for relaxed gun laws.
Lol, or the Hunters and Fishers party in Australia wanting silenced weapons, so less animals run away.
Short of shooting a wild bear trying to eat you, wtf is the point in owning a pump action?
Don't worry, i think i already know the answer.
