I love a good rumor that might even be true. I can now hope that, 40 years late, Ruger will finally make my 6" .22 LR Security Six, or as close as they're going to get to one. If true I will buy more than one as variations come out and/or my budget allows. My guess is most of you will want a shorter barrel but my first choice is a longer one, so long as they don't make it too muzzle heavy. A .22 with the external apperance of the early 6" half lug .357s is the best starting point. I'd prefer it in a 6 shot but that doesn't seem to be the modern way.
Regarding trigger pulls, the DA on the couple .22 SP 101s I've handled was a turn off. Their mediocre DA is not just a consequence of frame size. My J frame .22s have much better DA pulls. I've found that in order to retain reliable DA ignition K frame main springs can't be lightened significantly. I have backed out the strain screw by ¼ turns then kept a log of missfires. An adjustment that gives reliable DA with one brick often fails with a different lot of cartridges. I presume SP 101s and any future .22 LR GP 100s will be the same.
