I have two of them. Both are bone stock 2 1/4 models except for the rubber Houge mono-grips they wear. one is DAO, the other is SA/DA.
Both have digested several thousand rounds of full snort 357. The first one I bought tried to unscrew the barrel at about the 20,000 round mark. Ruger had it right in about 2 weeks, and no problems since. It's been shot enough since then to wear out 2 sets of grips.
The second one has shown no problems at all, but it is nearly due for it's second set of grips.
If I had chosen one of the wood options, they'd both still be on their fist set of grips. The rubber ones are great at helping control the recoil of full snort loads, but they do wear out, and have the occasional habit of hanging up on cloth, kinda like a pencil eraser would.
FWIW: I don't use spring kits. Too many folks reporting light strike issues, especially with the light hammered DAO models. Just polishing the internals a bit and a lot of dry-fire has smoothed them up nicely. They are smooth enough now that some folks I've let shoot them assume I've put in a spring kit.
