There isn't much I agree with TDC on but the reliability issued was solved years ago. Revolvers are not as reliable as pistols under field conditions. Any amount of sand, mud or crud will prevent the cylinder from turning. The US Military after extensive testing over 100 years ago chose the 1911 design because it was far more reliable than the revolvers of the day and not much has changed since then. I doubt there are many revolvers that would shoot 5,000 rds of ammo without cleaning and still function. Most quality pistols will do that and more.... and have.
All that said, where I disagree with TDC is revolvers have a place in the sporting/self defense community and sell well because of that. I love the ones I own but none would replace my CZ 85 Combat if I only had one to keep.

ps I don't own a Sig or Glock but if I did they would become one of three pistols I would choose from.
