Howdy,
I had J frame itis bad at one time when I started shooting. I have below average size hands and the little J frames seemed logical. I assumed the light weight and small size would equate to my getting good accuracy. What a mistake that was.
My cop friends pushed shooting double action (DA) as a way to develop skills. If you can shoot DA, you can shoot anything. DA shooting was a frustrating experience. Working that long, heavier trigger with a light gun was tough. I also discovered that tuning that J frame trigger was much more difficult than expected.
I must have had a dozen before I accidentally got my first N frame, the 28 Highway Patrolman. It felt huge. I then discovered for the first time what a nice DA trigger with some weight could do. It changed my shooting. What a giant mistake I had made assuming small grip size and weight equated with ease of shooting.
A mind is like a parachute, it works best when it's open. Once I had felt that nice DA squeeze with a little weight, I could get nice tight little groups. It was then easy to see why K and L frames had come along.
That J frame trigger, even after stoning and tuning, will never equal the larger frames DA trigger work.
With all that said, don't misunderstand me.
Every backcountry walk I take has my little 360PD along. It hits me harder than my 44 mag, but I forget it's there at 13 oz.
So NOOOOO , I haven't found the cure yet.
