IMHO, the change was a good one, but some folks never did get reconciled, sort of like the anti-lock people or the old-time southerners.
Well yes, I lived through some of that. At the time bullseye shooting was popular and a force that could drive sales. Colt had an edge, because ways had been found to shorten the thumb-cocking stroke to make cocking quicker. So far as double-action was concerned they often simply eliminated it.
Smith & Wesson had by far, the best out-of-the-box double action, and it was promoted by Ed. McGivern, a famous exhibition shooter during those days. But the bullseye boys proved to have the stronger influence on sales.
Being as that was, just before World War Two started, S&W started experimenting with making a short action, and in doing so moved the location of the hammer stud (pin the hammer rotates on) which improved the thumb-cocking feature at the expense of the D.A. pull. However further development had to be set aside until after the war.
Then they introduced the series of K-22,32 and 38 Masterpiece target revolvers with an improved "click" adjustable rear sight, ribbed barrel, wide spur hammer, and of course the new "short action."
But sometimes you can't win. It wasn't long before target shooter started switching to self-loading pistols. I still say that those long action revolvers offered "the best" double action ever offered on a mass produced revolver.
