I did the crane/cylinder flipping thing exactly once, at PSC with a gentleman's full-size revolver, before he and his friends politely warned me not to do that again.
And since then I have not ever done that again. I am not inclined to show my handguns to friends, family and acquaintances, much less discuss the broader subject of individual armament, unless I know they are on "our" side. After reading what randomoutburst wrote, I am not inclined to let anyone else handle one of my revolvers unless they own one of their own, or I have seen them manipulate one without abusing it.
