Yes, but the OP posted .22 WRF, which is the obsolete .22 Winchester Rim Fire. Looks like a shorter .22 mag.
I looked at the Single Nine on the Ruger website, and I like it, but I just bought a 1978 Single Six at the local fun shop, today.
I like it a lot, but the factory rear sight is a shiny black anodized aluminum and glares too much. I think I'll install a set of Williams FireSights.
I also want some thicker grips. I don't like the thin wood factory grips.
I'm thinking about sending some mahogany, sweetgum, and/or micarta to CLC and/or Private's and have some grips made.
I guess I could make my own, but it would take me a lot longer than the 6 weeks it takes for Private Schultz to make them.
Noticing how much space is between chambers on the Single Six, I better understand why Ruger started making it as a 10 shot.
As much as I love Taurus revolvers, I'd buy the single Nine over the Taurus in a heartbeat. What's not to like about a 9 shot Ruger .22 mag revolver?
I just wish Aguila would make a 60 grain, wide/flat-nosed .22 mag load.
That would be a bit of a thumper out of the revolver.
Just imagine a 60-80 grain jacketed (or hard cast) soup can projectile.
