I agree - go with an older S&W, if it meets your needs. That's what I did last fall - when I found the 4" 651 below. They haven't made 651's in over ten years, so that's the only way to go for a 4" SS .22 WMR. I had bought a 5" 63 (x8) from a friend's estate some years ago, followed by my 11/10 3" 63 (x8) purchase. I modded the 5" 63, spring-wise, but the 3" 63 is box-stock - and has a better trigger! The HiViz sight inspired me - I put one - the wrong one (Look closely - it's too long!) on the 5" 63, too - and all got 60 Pro grips. Oh... as to poor QC - the unfired 651's hammer spring's yoke was jammed in the hammer - not riding on the pin, as it should have been. Easy fix - smoother/lighter DA trigger was the reward. A CF hammer spring was an improvement, too. QC wasn't perfect in 1999-2000, either.
I was able to A-B my 3" 63 with a new Ruger 4" x8 SP101 last fall. The 3" 63 was more accurate, has a better trigger, and cost barely what a McD's Happy Meal would cost more than the admittedly overpriced because it was new Ruger did. Yeah, the 3" 63 is a nice package.
