First of all, glad that you and your mom are both ok!

I see nothing wrong with your actions! If two ot threee people get out a car yelling at me, pulling at my door handle and banging on the window, especially if they try to surround my car, my gun will be getting pulled as well. In my opinion, you were within your right to defend yourself and your mother. Glad everything is ok. And as someone said above, calling the authorities and saying something first may be a good idea.
