I have found a model 974 Rossi revolver in good condition and am interested in purchasing it. Does anyone here have any experience with this model? I can't find any info on it and am hesitant to buy something that may have built-in problems. I know that it was not produced in large quantities and that it has the built in compensator. Can it be rebarreled? Can the grip frame be rounded and what aftermarket grips would then fit it? Is it worth the extra expense of doing this? When was it mfg'ed?
