Pistols take a bit of hoop jumping to acquire, but not too bad. Pump action and semi auto shotguns are in a licence category that's hard to get, so pretty rare. Semi automatic rim fire is in the same category. Semi automatic centre fire is restricted to contract shooters, so very rare too. No folding stocks. No suppressors, except for an even smaller group of contract shooters. Could be worse, could be a heap better.
As a LEO I find that gun crime is very low, I am outside of the city though. Most criminals that have guns acquire them as payment for drugs, they use them mostly to stand over people for debts, not so much to use them for crimes against everyday people. It's not unheard of for them to turn them on Police, buts its fortunately very rare.
