Skadoosh and mordis, in my august opinion, do whatever you like. Just don't think that because you like it, it makes objective sense.
Skadoosh, you want to throw in complicated operating mechanisms to attack semi-autos... great, but Glock has been one of the most popular guns for a couple decades now, and the M&P line are gaining rapidly. Most (though not all) gunners who choose something more complex - such as a 1911 - tend to be enthusiasts who probably train a bit more.
With regard to ammo sensitivity - that has been addressed. Of course, I run my autos through a lot of testing with ammo, magazines, etc before I decide on a carry system. I've ditched my 1911s for carry, due to sensitivity issues. I have never yet had a failure in my M&Ps, although one could always encounter a dud round (I suppose).
Then again, I had a factory SD round squib in one of my revolvers, once. That'll disable a revolver real good.
I had a friend a few weeks ago shoot some non-brass cased rounds (he didn't remember if they were aluminum or steel) in his revolver. Cases didn't expand like brass, and instead of holding well in the chambers, they tended to slip rearward, and his cylinder kept binding.
I also know people who haven't properly tested their lightweight and scandium revolvers for ammo suitability, and have bought ammo with bullets of non-recommended weights. When the bullets in the unfired cartridges jump crimp, guess what? Cylinders also bind.
Let's see... shooting outdoors in cold weather, I was wearing leather gloves, and the leather of my trigger finger tended to bind up my M29's trigger after each shot, interfering with trigger return.
Same gloves, no problem at all with my M&Ps. And I'd suggest it would be nearly impossible to bind a 1911 trigger, even if they do have more complicated safety mechanisms.
So, in my august opinion, all systems have potential weak points. Many can be overcome through user training, and user testing.
As far as what to do for revolver guys... Well, for Skadoosh and mordis:
1) Enjoy your confidence in statistics that attacks are pretty rare, which they are.
1b) Hope you don't become an outlier.
2) Enjoy your confidence that if you are attacked, it will only be by one assailant. (Statistics for that one don't bear you out so well.)
3) Enjoy your confidence that bad guys will be psychologically stopped. (90% or so of the time, they will, without a shot fired. I tend to train for reasonable worst case, though... and assume attacks will actually continue.)
For the other revolver guys, I'd suggest what I do when I carry a mid or large revolver as primary:
4) Carry at least one other revolver, plus a strip or loader or two. (I like strips, as they can work with both my primary and J-frame, although they are slow.) Edit: this is out the window if I'm out in the woods and carrying a .44 magnum... at least as far as reload compatibility. I still usually have the 442, as well.
However, as noted earlier, my J-frame is normally a BUG to an auto.
