Thanks for the info EE and trplem, before you guys posted to my inquiry I got on Gunbroker and Gunsinternational and began looking around, I suppose the N frames are stronger then the K frames? plus, I called and old friend to discuss, he said he has a 586 no dash whatever that means, that he 'may' sell me.
I think a clean old N frame will be a better running mate for my 1955 45 acp.
