I also love the .22 Magnum. I have a few NAA revolvers in .22 Mag/LR and use them for CC with Speer Gold Dots.
I would jump on an 8-shot LCR in .22 Mag. I believe it would be more effective in many self defense situations than a 5-shot .38 Special. The extra shots and lack of recoil could prove to be the difference someday.
