As a police firearms instructor, I've used the tried and true wheelguns as a way to help a struggling recruits and in-service officers to improve their trigger control. Yea we use Glock's and theoretically they should be easy to control. However, they slap, jerk, yank and otherwise screw up their trigger pull. A revolver teaches them to concentrate on the front post and to control their 'booger hook' throughout the trigger pull cycle. It works very well.
Practicing with snap caps in your wheelgun will help you too. Likewise, mastering the trigger on a revolver will help you with ALL firearms. The two most important fundamentals of the six are? Sight alignment and trigger control. Don't expect perfect groups at 25yds from your J frame, but your Mod 15? You should be ripping out the center of the target (providing your sights are zeroed).
I had a young rook notice one day at the PD range that I was carrying my trusty old 3" Mod 10. He chided me about it so I offered a challenge. The AZPOST Qual at that time was still the 2 and 3 shot strings intended for revolvers. We shot the post qualification and I spanked him. I shot a perfect 250 and reloaded the 6 gun faster than he did his Glock 22. He was humbled and now has a new respect for the old adage: "Its not the gun, it's the shooter".
Keep practicing both on and off the range. You'll find that it will get better.
To paraphrase Obi Wan: "This is your father's revolver. The weapon of a blue knight. It's not as clumsy and random as a semi auto. A elegant weapon for a more civilized time".
