Just trying to find out what the difference is between the OM and the NM cylinders, for the Single Six.
Thanks
Thanks
xtratoy said:I asked this question before and this is the answer I received then. "The NM cylinders don't work in OM pistols. Not so much the length, which can be fitted (i.e. sanded to the slightly shorter length), but that the ratchet wheel (term??) is a different size (smaller on NM). OM = .625", NM = .58" IIRC." It seems like someone also showed a picture of the ratchet that appeared to verify the above statement.

Ruger got rid of the firing pin groove in the LR cylinder and began rollmarking an unfluted cylinder for the Mag. in late 1975 for the blue guns. For the stainless, these changes happened in mid-1976.
