I'm looking to buy a gun to defend my home that I can also concealed carry, however I want to use non-lethal rounds to incapacitate (but not kill) an attacker or home invader. I'm new to guns, ammo, and all that in general. If I'm ever in a situation where I need to use force, I'd rather have the police deal with it and just be able to incapacitate someone until the police get there. Any suggestions for a newbie? Thanks!
