Hi, Bart,
The folks who do executive protection are taught those techniques as well as shoving the web of the thumb under the hammer. That could be a real "ouch" with a hammer mounted firing pin but those guys understand that their job is to protect the VIP, not worry about injury to themselves. They will literally put themselves between the gun and the intended victim if necessary, so a burn from the barrel-cylinder gap of a revolver is not a big deal.
