Thanks for the quick responses.
The only fiber optic sights I have been able to find are the Meprolight, SDM Manufacturing from Smith and Wesson and Lumi sights from Cylinder and Slide. Anyone have any other recomendations or advice on these sights.
343 - I went to OU many years ago, however I reside in Southern Illinois. My kids are at the age where they don't need me much anymore (16 and up) and I am starting to have more time for hobbies, so I have been thinking about getting into some local competitive shooting. Possibly with the revolver and also possibly 3-gun. Not quite ready, so I haven't found out if there are any loccal matches.
johnmac - I'm using the Hogue grips which came with the TRR8. The only thing that bothers me about the grips is where my thumb wraps around the grip. It seems like my thumb rides too far out, like the grip should be a little thinner at this spot.
