I believe that it IS 'possible' to do this conversion.

The Security Six and all of it's 'variants' were built on the same robust medium-size frame with heavy duty parts.

The Service Six & Police Service Six were introduced to cash in on the Law Enforcement market.

Like the Security Six, the Service Six was mostly chambered in .357 Magnum. But since many Police Departments required .38 Spl. ammunition only ... Ruger also chambered Service Six revolvers in .38 Spl.

I don't know what re-chambering would cost you $$$ ? ... but a Service Six .38 Spl. in 'nice' AND ORIGINAL condition would be a very desirable aquisition. These 'old' Ruger Security Six type revolvers are becoming much popular in demand and will only increase in value.

I'd leave this one alone AS IS ... and maybe eventually buy another Ruger SS chambered for the .357 Mag.
