I know a guy who fellated a pistol but held it wrong and ended up with his upper lip and nose messed up. He eventually took his old van to a secluded location and ran a vacuum cleaner hose from the tailpipe into the van and gassed himself. I wouldn't use a gun solely for consideration of the people who have to scrape my carcass up and deal with it.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
