I started with a revolver, a Detective Special, when I got my carry in NYC in 1972-3. It was a natural for me, as I always shot my uncles 38's at his home range. The grip is different, left hand lower, more of a cuping/support movement. I was extremlly accurate with snub nose guns, and had one on my carry for over 20 yrs in NY. I also later went to a walther which was easy to shoot after firing a revolver with a short barrell all those years. I think it made recoil less important and less noticible. If you can fire a 38 or 357 accuratlly at 25 yards, an auto seemed to be a lot easier at least for me.
When going the other way around, "starting with auto pistols" I noticed it was more difficult for others to get the hang of it quicklly. If you don't support it right it will be all over the target, if you can get your left hand under and behind the grip, it is much easier than taking a high grip like an auto, it's just an inch or so difference, slide the thumb bone part of your hand under the opposite one instead of along side it. Especially with the factory small j frame size grips. That way you have both hands supporting the rearward movement of the firearm. instead of one hand taking the majority. It will be like putting the gun in a vice. With practice you will be able to cock the gun with your trigger finger without dropping the hammer, this makes for very accurate shots when necessory, again avoid cocking the gun and shooting single action, it is a bad habit to get into unless you are shooting a single action firearm. A good trigger job, as suggested is a good investmant. I shot hand loads from my uncle for my carry loads, he shot competitivelly and I still have some from 25 years ago.They were a copper jacketed hollowpoint, I don't remember how many grains but they were extremlly accurate. I still feel that it had more power than my 9 mm. I had a model 60 for the longest time of all.
