a tendency to “chase the dot” because it moves a fair bit, and I’ve seen many people at the range, try to snap off a shot as it swings across the target.

Good to know. I've been thinking about getting some for my Taurus 85. I thought I was a good shot until I started using that snubbie. I found that instead to focusing and concentrating hard on sighting in the target, I do better if I just casually squeeze the trigger when I see the target is lined up in the sight. It's hard to explain, but it's different shooting it than shooting a Colt Python or a rifle or something. You have to stay really relaxed if you want to shoot a tight group.

If you want to get smooth with a DA revolver, use an old trick of exhibition shooter Ed McGivern from the 1930’s (he shot 5 shots from a .38 Smith in 9/20th’s of a second into a playing card sized group). Put a dot of paint on a full length mirror, and put the muzzle on it. Dry fire repeatedly, trying to keep the muzzle on the dot. You can see what your trigger pull is doing to the aim. Get smoother and quicker over time. That trains the muscles.

And you'll drive yourself crazy trying to be a good shot with a snub nose. They are not and cannot be accurate with a barrel length of 3" or less. Belly (arm's length) shots only. You could have a measure of repeatability if you load your own down to the grain, but unless you're a maniac you probably have better things to do.
