But if you get used to allowing the trigger to snap back the way it is supposed to, I'll bet you a donut your problem will go away.
Maybe. Maybe not. As I mentioned, most revolver shooters are unaware they ride the trigger on the return - and that likely includes posters here who've lectured us on "proper form". I don't disagree with "proper form", but simply have to note that most don't likely adhere to it as strictly as they believe.
Also, a sluggish return means the return is on the edge of reliability. There's no margin for error, and additional crud or dryness can cause issues even if the trigger's returned quickly.
Why's it matter? First, as mentioned, a return that's on the edge of reliability is exactly that. There's no room for dirt, or lube or technique issues.
Also, when things speed up, trigger riders are likely to short-stroke the DA trigger if the return's sluggish for any reason. A lot of competitive revolver shooters want that uber-light DA, but immediately find themselves short-stroking the trigger. That's a real killer in competition. I admit to this myself, and one reason I don't go uber-light on my match revolvers.
And check out the great Jerry Miculek short-stroking a Python (@ 3:18). JM uses a stronger-than-stock rebound spring, and it's been my strong suspicion he rides the trigger on the return. As a result, he immediately locks up a stock Python.

If this is a range gun, and all you'll ever do is shoot nice and slowly at a paper target, you don't likely have to do anything, other than what's been advised - get off the trigger fully and let the trigger reset quickly. But if speed and/or no-excuses reliability is important to you, I'd look into that sluggish reset.
