Can you buy guns in Australia if you do not have criminal bacground? In USA, as long as you are not a criminal, you can get 10 guns easily. It is not the gun that you need, you will also need a lot of bullets to practice. Our police friend told us, we can get a 5000 round pack cheap. But then except practice a few times a year...it is a waste. Those reloads sometimes come out duds.
