S&W just re introduced the 66 2-3/4 357 mag 6 shot which is the same size as the Security and Speed Six. The 4 inch model re introduced 2 years ago has been flying off the shelves. I think Ruger needs to bring back the Security and Speed Six or lose market share. I have 2 of the new 66s on order. I own more than 50 Rugers and would love some more.
