Everyone,
Thanks so much for the details and recommendations. I feel like I understand the reliability issues a lot more now. I will be headed to the gun show tomorrow and will let you guys know if I end up picking something up. Leaning towards the SP101, but the Heritage Firearms are tempting too, since this would just be a "fun" gun. I have a S & W Shield in 9 mm if I need to CC.
If you just want a .22 revolver for fun, with high quality and reliability, I'd look no further than a Ruger Single Six.
Pay a bit extra and you can get it with the extra .22 Magnum cylinder if you want just a bit more versatility.
