I don't care much for single action .22's, small hole for the ejector rod is the exact definition of "aim small, miss small."
I'd rather have a double action, sadly not as many good/acceptable options there, but Ruger has the LCR (wish they'd make a longer barrel version tho) and the SP101, both 8 rounders. They came out with the GP100 earlier this year with 10 rounds, but for its size it's another Ruger boat anchor. To me, I don't need a .22 larger in something larger than a K frame.
Charter Arms makes a .22... in a 6 shot cylinder only. Pass. Every revolver should be able to hold 8 rounds of .22 Long Rifle except the super small NAA's.
Taurus is the next best bet for something decent. They make a Tracker model that's 9 shots and has a .22 Magnum conversion. Very big revolvers, but a convertible .22LR/.22Mag in a swing out DA/SA is not common.
I think Rossi makes an 8 shot for about $300. Size is large, but it's only 30 oz heavy which in a revolver isn't the best, but isn't the worst either. Last i checked, everybody was sold out of the Rossi .22's.
Like I said, I'm waiting on Ruger to make a longer barrel LCR. Might be waiting years for it, but the wait is worth the wait. At least, until Kel-Tec decides to jump into the revolver market with their own version of a wheelgun:
EDIT: And don't hesitate to look at the used revolver market online. There are a lot of old companies like H&R that made good .22 revolvers, both with swing out cylinders and top break models.
