Sounds like a South Paw might need a DA only Sig 226. No decocker needed and they were selling them right the last we spoke of it. Some kind of yankee police trade ins. Can’t imagine it being any more strenuous than learning to shoot a DA six gun in the DA mode. Try this link. They may be all metal.
