I did a search and looked in the SCSW but nothing I seen seemed to idicate adjustable sights on a M64. A M67 would be a M64 with adjustable sights correct?
I found a couple of them for sale but wasn't sure about the sights. Did S&W do a special run?
I haven't bought one yet but I'm thinking real hard about doing so.
Mike,
A 67 would be as close as you could get. The barrel tapers would be different. The 64 was offered in heavy and "pencil" tapers. The 67 is considered a "tapered" barrel, I think, but it's somewhere in between heavy, and pencil.
Gunsmiths putting K-frame adjustable rear sights on was a popular thing back in the 80's when lots of fixed sight 10/13/64/65s police trade-ins were on the market cheap.
