I like revolvers. No jams and they take abuse well.
That move that Trayvon put on George Zimmermann, of grabbing his weapon and holding it tightly, was a big of Big House lore that he got somewhere, which would have worked if Zimmermann had been carrying a revolver.
Zimmermann with a semiautomatic purse gun = live Zimmermann, dead Trayvon. (Right outcome.) Zimmermann with a revolver = another doleful murder statistic, and Trayvon's a made guy heading toward his goal of being totally hard and ruthless.
