I can't prove it, but I think a similar market exists for a high quality double action revolver
Of course there is!
You and I are part of it, as well as several others posting on this thread.
But unlike the considerable number of 1911 fanboys we don't have enough tail to wag any dogs, so we shop the second-hand market for the guns we
know are better, at least from our perspective. Most of us were brought up in generations that bought these older guns when they were current production and are well aware of what they represent. But those that are following us have different tastes and likes.
Manufacturers - at least successful ones - keep close attention to what is, and what isn't popular with the larger segments of the overall market. They know that popular entertainment media (TV, movies, video and computer games, etc.) point younger shooters toward black, large magazine capacity, rifles and pistols, and so far as handguns this is what they see in law enforcement officer's holsters.
They also like to rip off a string of shots without paying too much attention to what the holes on their targets look like, or if the total number of holes are equal to the number of shots fired. Rapid, continuous fire is the name of their game. In this environment a revolver of any quality doesn't attract much attention. There are of course exceptions to the rule, but for gun makers most of them are not of substantial importance.
Regardless of what we like, more and more folks seeking something for "pocket protection" are turning toward small, flat, lightweight, double-action pistols with polymer frames. Manufacturers are delighted with this because these pistols represent high profit margins. They look at the bottom lines on they're spread sheets, and this, and only this, dictates where most of the R&D money will go. High quality revolvers don't make a blip.
On the revolver side of the picture there are two kinds of people. Those who understand the realities, and those who refuse to.
But that’s O.K. I’m a stubborn old man who is well past his prime, and I don’t give a rip about what others like or don’t. You should join me.
