I can’t comment on the new M66’s
But I have had this M66 since new, 73 or early 74. I like it a lot obviously since I still have it. 😁
I do shoot +P .38spl handloads in .357 cases in it mostly now. It has had a lot of various ammo shot out of it. Carried it when I was in the sheriffs posse back in the 80’s. It’s been on hunting trips etc. Not a problem with it at all. The SS is a lot easier to keep up than a blued M19. Just a great revolver.
