As I said before, does anyone have any real world experience?
Yes, all the way up past Browning .50 cal HB MG. Additionally, taught Basic Rifle Marksmanship, Basic Pistol Marksmanship and was an armorer.
The primary issue some have with semi-auto is that they are more likely to jam than a revolver. Yeah, yeah, yeah, semi's have come a long way. Regardless, the reliabilty factor for a revolver is much greater. If more people would actually perform preventive maintenance (clean and maintain the magazines, check the spring tension, use quality ammo) on semi-auto's, they would definitely be more reliable. Problem revolves around the fact that Joe Gunowner buys a cool looking Glock or Ruger for home defense, pops a few caps then loads up the magazine and allows it to sit for two years. Then he either takes it to the range, back fourty or worse, attempts to actually use it in a real world situation and the thing jams because of the inherent design of the magazine. On the other hand, Joe "the cheap @ss" Gunowner uses low quality reloads from his buddy Fred "know it all" Reloader and they more than likely jam too.
For reliabilty, I'll stick with a revolver or bolt gun any day. I say that, but my favorites are still my AR15 HB Match, M-1A and Browning Hi-Power.
