Looking for material to read about concealed weapons

[skep203]

Does anyone know where I can read up on the laws regarding a concealed weapons permit and when use is justified?

For example, I want to know when drawing and firing is justified as opposed to firing and ending up in prison for life, how to recognize an actual threat, etc.

Thanks

Penal code on Lawful Resistance - 692-694
Penal Code 197

Then, try the old but still useful Massad Ayoob book, "In the Gravest Extreme".
