Looks nice a nice addition to the line:
Ruger® SP101® Double-Action Revolver Models
I always liked the S&W .22 revolvers, but balked at the price. This one might be more reasonable.
Of course, my own plinking needs are met with my ancient Iver Johnson "Sealed Target 8" revolver - though the sights are lacking.
Might have to save up for this Ruger, then...
