I voted for the 9mm, and still hold with that. I don't know about you, but I would try to avoid killing someone if at all possible. I would think that racking the slide in front of a thug would be a good non-lethal way to make him change his mind about attacking you. If he already has a gun pointed at you, don't you think he'd shoot you before you could get your weapon out of it's holster? Most criminals are both unintelligent and cowards, but seeing you rack the slide on something that could kill them would probably make the cowardice take precedent over stupidity.
