I heard pepper spray or something less than lethal because if you have to shoot the jury will see that you used less than lethal before you shot. Personally I think it depends on the situation. I get a split second to react to something that they have a ton of time to think over and pull apart.
Glock 22 15+1
Extra mag 15

That's actually something I've thought of doing before. A wallet to give up if someone gets the drop on me.
As of now its just my little Snap-On knife and my wallet and keys. I'm taking my CCW class in a week then waiting for Arapahoe County to to sign off on the permit, so no G19 carry yet. But I will be adding that and a mag to it when I'm legal.
It contains stuff of no consequence: couple of business cards for local detectives, those fake credit cards that you get in the credit card offers, various bills I copied along with a real dollar, and fake photos. Nothing with real information other than the afore mentioned business cards.
I carry it weak side and practice pulling it out so the action looks natural.
