I've always preferred semi-automatic, but it's quite simply, a matter of personal preference. If you need more than 1 shot you're in trouble... before anyone brings up the amazing speed on the professionals and a revolver that's simply not the norm. I love semi automatics, but again, that's personal preference, all major brands are manufactured with precise standards, yes a semi has more "parts" to go wrong, I'll take the design, convenience for magazine reloading and fancy features. Arguing about one being the other is the same as arguing about wearing a helmet, voting for/against an issue, or whether someone is "hot" or not, so long as an "informed" decision is being made noone's mind is going to be changed.
