I have been looking at a mint in the box sw 59 one blue one nickle . I know they are an older gen gun were they any good or a jama matic ? A old beat cop here use to pack a blued 59 He was the only uy here that did he was not a gun guy but said if never gave him a problem .After a lond love affair with the 59 he got a beretta 92. Some have a short extractor and some a long thin type . Are they any good ?
