Meanwhile, back to revolvers, and single vs double action, on a whim I got out my S&W Model 17-5 last night. Huge difference from my Model 28 - the trigger moves back smooth as molasses. The gun doesn't wobble from the trigger movement. I tested it in dry-fire, and I suspect I could shoot it either way, and get similar results.
Maybe I'll get to try it for a short time at the range tomorrow morning.
Something else I noticed - after all this shooting with the Model 28, two handed, I found I could easily shoot the Model 17 with one hand. The last time I tried that, I wasn't strong enough.
I've got a lot more 22 ammo than 38; that also makes a difference.
One of the problems with the 28 trigger is it was not built as a target gun, it was purpose built for a LEO gun and has heavier springs in the trigger than we would want for a target gun. Single action in my two Model 28s are really good, especially in my 1957 model because I have shot it the most.
Double action will require a trigger and spring job. I hear people say that the 28 is the same as the 27 except for the finish. It isn't the same inside, not polished, not sprung for optimal target shooting and so on.
As far as Hitchcock45 abilities with a model 28, unless your 6'9' and have huge hands like he does, you will never equal him with any N-frame.
I'm normal sized and a Model 28 is just to big of a frame for me to shoot double action well, for the size of my hands. I do it but I will never be a good shot with it in double action. I just doesn't feel natural for me, like a smaller frame does.
A trigger and spring job will go a long ways towards where you want to be though, I found that out when I bought my 57 and it was at least twice as easy to shoot double action because it was optimized as a hunting/target gun. Had the right springs to start with.
But when I bought my 6" 686-4, that when the rest of it came together for me as the smaller frame fit my hands better and was just more natural to shoot so my groups really improved the most with it.
Your 14 is the same way, that's why you shoot it the best. K and L frames are the best size frames for most people.
Get a spring kit and a polish job on your Model 28 and you will notice a big difference but unless you have big enough hands that the 28 fits you naturally, don't expect it shoot it as good in double action as you do your 14.
