What should you not use in self defense?
Just to start building the list -
Rock Salt - it'll just piss them off
Your own reloads - I've heard this a lot. Is this because of loading consistency? Or because making your own man killing bullets is less evil than buying them at the store?
a fully automatic weapon - I read about a ruger employee servicing an AC556 that had to use it, and the DA went ape shit over it.
"less than lethal" rounds (bean bag shotgun rounds) - they're not un-lethal, and if you had to use something potentially lethal, why didn't you?
What else should be added or debunked and removed from the list?
And yes, if your life is in danger, and ALL you have is a Glock 18 with reloads - by all means, use it.
