I've had my Ruger Security Six for several years. The grips are custom walnut, and I swear they must've been made for my hand! The fit is incredible. Don't know who made 'em. The Smith&Wesson Model 17-3 in .22LR, is a newer acquistion. I had been wanting a really good .22 revolver, as I already had a few Semis. I have not been disappointed. The grips are black plastic Pachmeyers, with the Bill Jordan signature.
