Well my feeling is that like a 1911 pistol, a revolver is a gun aficionado's choice.
The "plastic fantastic" craze started by the G17 in the early 1980's captivated the attention of the general public. Who remembers the metal scanners being overcome by the bad guys carrying "plastic Glocks with ceramic barrels and no metal parts" in the Die Hard 2 movie? As more compact models were released and more people in the US opted for concealed carry they became more popular and sold well. But I would guess that most were carried regularly but seldom fired at all.
Just like the .40 epidemic in the 90's where if you carried a .40 you were considered a lot cooler than if you carried a 9mm (well at least in the movies



).
Like the 1911, revolvers suffer from the stigma of holding less number of rounds. They also tend to have a slightly longer sight radius and be more accurate than the Tupperware guns and 01/02 CZ's.
Today the most common pistols I see in holsters at competitions are the CZ SP01 and the SP02 Shadow. But give those shooters a 1911 (like I did yesterday with a young lady shooter) or a nicely set up revolver, and they start to realise just what they have been missing.
I have just come off a 12 stage 1 1/2 day competition where the squads were mixed with Classic (single stack), revolver and production (CZ) shooters all in the same squad. My 10+1 9mm 1911 times, accuracy and scores more than held their own against the 16+1 CZ crowd, but when the revolver shooters were on the line my envy was clearly showing. Fast, smooth and accurate, those wheel gun shooters made it look so easy.
I doubt that the revolver will pass from general use anytime soon.
PS: that young lady shooter is going home this evening to put her SP01 away for now and start playing with her dad's 9mm 1911. She will be back on our range in 5 weeks to shoot it in my club's annual Classic Division Match. And as I told her father he should prepare for her to want to switch divisions afterwards. Her comment after firing half a mag out of my Kimber? "I really like this gun. It is so much easier to shoot than mine".
