Coats Open
I don't know what to call this, a cheat or a glitch, and I don't know whether you know this or not, but walk up to a merchant. Do whatever you want to do, buy or sell, or tune up your weapons. Then press B at the merchant's menu, but before the merchant closes his coat, shoot him. His coat will still be open as he dies.
P.S. This only works if the merchant opens his coat when you talk to him.
