22 Mag 6 1/2 inch barrel old model Single Six that I bought years ago, just because I never knew Ruger ever made them. Let us know how it turns out!! If it comes back as SC6M you have a unicorn!!! That invoice stated it was part of a larger order of say 30 or 35 guns (I don't remember now). with it, I would still contact the factory to see if it was shipped as SC6 or SC6M.Īt least 15 SC6M were produced for a distributor. If it was shipped as a convertible, then Ruger scratched the front of both cylinders with the last three digits.īut if it only has a Mag.

The only one that had been known was 555430, however we have no idea of the whereabouts of that revolver today. there were indeed at least 15 of the model SC6 Super Single-Six with 6-1/2' barrel shipped from the factory as.
