Of course you can defend yourself with a gun. But it comes down to, should you and could you.
If I am being mugged on alley by a thug with a knife, me pulling a gun on him is going to get more trouble to me.
Here where I live, the fact I would use a gun to defend me would land me in to jail for around 10 years - for gun crime . (Because here we are not allowed to carry weapons on public, at all. No questions, no but... And guns that are being transferred need to have a lock on the trigger that can only be opened with a single key or kept in a case that is locked.)
So here you couldn't...
And personally, I wouldn't or couldn't. Being pacifist and all...
