A revolver and an automatic both have strengths and weaknesses for self defense and concealed carry. I won't go into detail unless someone asks.
I don't think that you would be at a disadvantage with a revolver for self defense if you identify a revolver's weaknesses and train to mitigate them. Different people have different preferences.
I've made some observation watching and participating in IDPA. Semi Auto shooters tend to shoot until they hear a click which means that they shoot until the reach slide lock. Usually, they do not count their rounds and are surprised that their gun is empty. This habit can be changed with training and practice.
I compete with a revolver and I am very aware that I have six shots before I can reload. I try to make the first six count. As soon as I have fired my sixth shot, I start reloading.
Revolver Advantages:
1) Selecting ammunition starts with accuracy, not reliablity
2) greater variety of ammuntion will function with a revolver
3) no safety gadget to push, pull or poke to get the revolver into action
Revolver disadvanatages with sugestions to mitigate:
1) slower to reload -moon clips like S&W model 625 in 45acp, or S&W's 10mm revolver, and practice, practice practice
2) tougher to conceal -change your jacket/cover/ review your wardrobe People conceal large revolvers every day
3) capacity, 5-7 shots? -solution, practice reloading!!!
4) change of grip most likely needed to reload -solution, practice
Semi auto advantages:
1) flatter, easier to conceal
2) reloads faster with a magazine
3) capacity for wonder nines
Semi Auto disadvantages:
1) ability of ammuntion to function -solution, find the ammo that feeds best and shoots accurately
2) Can't change from Super light to super heavy loads very easily -pick your carry load and stick with it
3) magazines get damaged and cause feed problems -solution, take care of your equipment.
4) safeties and magazine release -solution, practice!
5) malfunctions -solution, go to #1 and practice malfunction drills
I wouldn't have a problem with a revolver for conceal carry or home defense. I think that one issues is being overlooked. If you are in a situation where you are using a firearm to defend yourself, I would also think that you would also be trying to escape from the goblin. I would think that 5-7 rounds would be plenty to make the goblins think twice about making you a traget of assault, convince them to take evasive action rather than continue assaulting you while you try to get away.
Also, how long would it take for a goblin to realize that you have a revolver? You shoot 5 times for example, is the goblin going to realize that you have a J frame that only holds 5 rounds? is the goblin going to risk injury to themself on that guess? Suppose that you fire 6 rounds, does the goblin know that you are empty or do you have one of S&W's wonder revolvers that hold 7 rounds (686+) etc. I bet that the goblin doesn't think "that sounds like a 357 magnum or 38 special" when being shot at. I'd bet that they think "oh crap, I was going to make an easy mugging and now this person is shooting back at me! How do I get out of here?"
There are definitely advantages and disadvantage to any and all self defense and conceal carry systems. The bottom line is to emphasize the advantages and try to decrease the disadvantages through practice, equipment change/modification or other method. That's my thoughts on it.
