A few suggestions, just because I'm a revolver fan, and I hate to see anyone give up on them:
Herrett's Stocks, Inc., so the gun fits
Reduced loads, so you can focus on the basics, maybe at closer ranges than you usually shoot.
Lots of dry fire practice, maybe 50 dry fires at home for every 10 live rounds at the range
Reasonable expectations. You don't mention group sizes, but I would expect to get better groups, especially at long range, with the T/C. Also, don't measure your abilities against anyone but yourself. Try to shoot better than you did the day before, not better than Jerry Miculek.
Have fun, and put the paper targets away for a while. Shoot things that splash, pop, burst, clang, or fall down.
Try a different brand of revolver, as subtle differences may make a big difference in how it shoots for you.
If you still had that 41 mag, I would have encouraged you to give up revolvers, and sell that one to me!

Too bad, it sounds like you already sold it. :cry:
