The revolver vs. auto argument will go on forever. It is really about shot placement and what you are trained to use. I had to use my service revolver more than once during my career so I'm wedded to the wheel, but that's just me.

At 65 I'm too old to even think about reentering LE and have no desire to. If I HAD to I'd probably want a revolver, but that is a real pipe dream (thank goodness).
