Just because it's not one man's best choice doesn't mean it's not a good choice for another.
I really like this statement. Simple and completely true.
Whatever gives you the most confidence (assuming it is reliable and you will actually carry it), go with that. Easy. If the thought of having less than 17 rounds in the gun makes you squeemish, doubtful or uncomfortable, don't carry anything with less than 17 rounds. OTH, if you are like me and you've been able to induce "limp wrist" failures in many autos with ease and it leads to trust or confidence problems, go with a wheel gun. Again, easy.
It's especially easy when what you shoot best is also what you are most confident with, which is also something you'll actually carry and not leave in the car. I consider myself fortunate that I shoot medium to large frame revolvers consistently better than anything else, I have more faith in them working than other guns (yes, they can break) when it counts, and I find them easy to carry.
Disclaimer: I have no hard data to back up the following, this is just my gut instinct on the matter. Most people seem to say that running out of ammo is the most common failure in a gun fight. I actually believe it is when you run out of something else: time. And that is probably just a result of not having the proper mindset (the mindset to "do whatever it takes" to survive), picking the wrong equipment, not being familiar with it, etc.
Perhaps I am mistaken, but that is what I believe and I'm sticking to it, that running out of time (which ties to mindset/preparedness) is the most likely failure in gun fight. That influences my equipment selection. I think that in a gun fight the one who lands the first solid hit is
probably going to be successful. Not the first to miss with the first 2, 3, 4, 5 ... 15 shots. Therefore, I tend to prioritize my ability to draw and put well placed shots on target quickly, using the sights or just point shooting. The gun that allows me to do that best gets the nod from me.
So when I pick up a medium to large revolver (particularly S&W K and N Frames), assuming it has stocks on it that agree with my hand (they're easy enough to swap out ... and there's a big revolver advantage that I don't think has been mentioned yet) it just feels
right. It aims so naturally in my hand that sight alignment just sort of happens without thought so drawing and shooting happens without a lot of extra concentration.
Autos, OTH (often big chunky butt double stackers and Glocks in particular). I don't know, many just don't work as well for me. I respect Glocks, but for me the ergonomics are just plain dreadful. But you know, others find them spot on. Despite that, whenever I pick up a Glock I try to imagine in my mind what kind of freakish, 7 fingered ape hands Gaston must have
.
So in the end of you are hot stuff with a 20 round wonder 9 and you sleep soundly with that choice, by all means, go for it! If in the end you are hot stuff with a 5 shot Chief's Special and you sleep soundly with that choice, by all means, go for it!
Okay, I'll shut up now.
