mljdeckard -
In response to your comment that "You don't have any semi-auto anything that is 100% reliable," that's not what I said - I said I've got an AR and several autoloading pistols that SO FAR have been 100% reliable, and that IS true. I'm sure that eventually they will fail me at some point, but make no mistake, anything made by men will fail, no matter how simple or robust. Just because you haven't seen a revolver fail doesn't mean they are perfect, either - as some have pointed out, when an autoloader goes down, an immediate action drill can usually bring it back into the fight, but when a revolver goes down, it's not coming back up before a trip to the 'smith (some seem to think that just because they can't SEE any springs to wear out in their revolver, they aren't there, but believe me, they are).
Besides, getting back to the point that military and tactical teams use semi-autos, I have to be convinced that the reason that serious operators NEVER use revolvers or lever guns (and only really use pump guns for door breaching, as even military shotguns are going semi-auto - please reference the Benelli M4) is because, when treated right, the reliability ISN'T an issue - the ease of operation (better trigger, faster reloads, no manipulation of anything for immediate follow-up shots) IS. And treating the gun right shouldn't even be part of the argument - all guns should be treated right (all of mine, at least), and I've never had a problem doing that.
Again, I don't think that the marginal benefit in reliability that a revolver has over the reliability of a truly modern, quality manufacture handgun (HK, SIG, XD and even Glock, among others) makes it a better choice. To me, the autoloader still wins for trigger, magazine, etc.
I can give the pump shotgun vs. autoloader up, as I don't feel as strongly about that comparison. But I'm stickin to my guns (sorry about the pun) regarding revolvers vs. autoloaders, and levers vs. semi-auto rifles, as well.
Again, none of this is to say that there aren't valid reasons for liking the other. As I've said (and will continue to say), to each, his own - different strokes for different folks, all of that.
In the end, I'm just glad we all have guns to debate about.
