My local pusher had a few Single Six 50th Anniversary Specials last fall. My wife picked out the prettiest cocobolo stock they had, and gave me the Single Six for Christmas. I rationalized that the short barrel and lighter weight vs the ss model would make it handier. Gone also was that adjustable rear sight... I recalled a friend's 6.5" ss SSS... he was always adjusting that sight. Combined with the slow reload, he sold it @ 2 months. As a plinker, the fixed sights would be nice... in reality, they are very close with .22 WMR's. It is an easy to grab and mentally adjust (aka 'Kentucky windage') for plinker with either cylinder fitted. I like the standard Blackhawk size stock, but others may like the smaller Bearcat's stocks.
Of course, the best .22LR plinker, at least to me, is a Ruger MKII - especially the KMK-678GC with a 2x28mm handgun scope fitted, like mine. Heavy and big, but super to shoot - and frugal. Heck, the most fun you can have with a dollar's worth of ammo. I'll bet even a standard 4" blued would be fun, too. And - a few magazines really help. I trust the new MKIII's are just as much fun. My MKII is my only evil-bottom-feeder, my remaining collection being all revolvers. Admittedly, that SS would go long before the MKII.
