1) They are too complicated, in that when they fail it is a serious failure, where when my Glocks fail there are many fewer parts and the parts are much cheaper and much easier to replace without special tools (in the field)
2) Revolvers always leak "hot gas" out the sides of the gun, unacceptable and very distracting for follow up shots
3) They are uncomfortable to grip (even the ones with soft rubber)
4) They are too heavy and not well balanced (nose heavy)
5) I understand that many people claim they are more accurate, however, the vast majority of the people that I observe at the range with revolvers are spraying bullets all over the target, worse than beginners with a service sized semi-automatic. The times that I have shot revolvers, my accuracy was unchanged from my Glocks or 1911.
Strange - for most of those points, I see the same thing, but the opposite of what you describe.....
1 - complication - for most people, and me in particular for many years, the problem I had was cleaning. While cleaning a revolver is quite simple, it took me forever to feel comfortable in doing it with a semi-auto. As to shooting, with a revolver, you just pick it up and pull the trigger. Racking the slide, remembering to unlock the gun, and dealing with casings that didn't eject properly was FAR more complicated.
2 - I know that hot gasses can theoretically come out the side, but on a good S&W, I've never noticed that, let alone paid any attention to it. If it's distracting someone, I think it might be a problem with the gun. What DID distract me was the empty shell from my semi-auto flying up into the air, sometimes hitting me along its trajectory to the ground.
3 - Uncomfortable to grip - While my hand feels just as comfortable with one as the other, I've never had the revolver cutting my hand as it cycled, which used to happen to me with semi-automatics before I learned how to hold the gun to avoid it.... For years, I used the soft rubber grips, but then switched back to the original wood. It just felt "more comfortable" in my hands, but that's just me..... Maybe I'll try soft rubber again if I can find a pair that fits my hands better.
4 - As to being too heavy, and nose heavy, all things being equal, I find that a heavy gun (revolver and semi-auto) is more stable in my hands - less "quivering", and less likely to fly up from recoil. I will agree with you though that a lighter gun feels more comfortable. As to nose heavy, the longer the barrel, the better I can shoot. But yeah, the longer the barrel, the more nose heavy the gun gets.....
5 - accuracy..... I think you get all the potential accuracy you can afford (buy a Wilson for $4000, not plastic for $400) and how accurate you will be has far, far, far, far more to do with how much you practice, and how well you follow the advice of those who know better...... than whether it's a revolver or semi-auto. You can't buy accuracy. You have to earn it.
I think you left one thing off your list "image", or "looking cool". For me, when I see a 1954 automobile, I think that's really cool! For a 2014 automobile, I usually think it's a shapeless blob. If I want "cool", I want something that looks "cool". In 1954, all my friends and I wanted toy revolvers. In 2014 (if kids were still allowed to play with toy guns) they would likely be semi-auto handguns, or maybe even something like an AR-15......
