Anyone can still go get a gun as long as it's not automatic in any way. You might tell them it's to keep the rabbits out (or some such thing). You're just not permitted to fire a gun in an urban area, except at a rifle range/shooting club, and they're usually on the fringes anyway.

There would be restrictions if you'd been convicted of a crime, especially one involving a weapon.

I'm sure there are other restrictions, but none that would stop an average law abiding citizen from owning a gun, provided they had the required storage facilities for said gun.
