Erich's comment is kind of interesting. Yes, mere handling by LH doesn't impart any value in and of itself. But the combination of features was good enough to generate some demand when made and that demand remains. Why they could understand and see the value when the factory couldn't is part of the problem. The factory or most factories are driven by the sales department. Sales types are often not shooters and only rarely gun nuts (like us here.)
The old story of Don Wilkerson and his "Don Wilkerson Special" come to mind. He was the Colt expert of long standing. After Ray Meabaum passed, Don's stature even grew more. He discovered that it was possible to put a 3 1/2" barrel on a SAA and still incorporate a full stroke ejector rod. Colt's had made that barrel length in the past, but didn't put an ejector rod on the guns (Sheriff's) or the 4" (Shopkeeper's). So Wilkerson called the factory to order up a few. Of course they laughed at him. Said they weren't going to do it. So he said how about 20. They still laughed and said no. When his order got up to about 100 guns, they changed their tune. To a nearly bankrupt Colt facility, 100 guns presold was just too good to turn away.
How does Dick know this story?
A few years back we were sitting at our tables at National Gun Day and a prospective customer (we thought) came walking up. He instantly focused on the Wilkerson Specials and asked innocently enough "whats the story on those?" John, my table pard, went into the above spiel. When he finished the speach, the guy on the other side of the table smiled at him and said "I know, I'm Don Wilkerson."
It was fun seeing John packpedal and turn all red. But Wilkerson was a gentleman and laughed. Said it was pretty accurate.
Often the user of a product knows more about it than the people who make it. All the manufacturer wants is to produce it and ship it, to be forgotten forever. Consumer wants and needs are often given little interest. Think S&W and the infernal locks. They do what they want, build what they want because its convenient for them. They often don't give a crap about anyone else as long as their product sells.
That Horton has better insight is because they're closer to the customer than the manufacturer. Some of the better gun shops probably could add a few things, too. But the factory has insulated themselves from reality by using a distributor network.
