That gun is right up my alley. Depending on how deep the pits are and the condition of the bore, I'd attempt to restore it. If the pits are too deep, I could fill them in with copper then get it nickel plated. I've seen some pits filled in with micro tig welding. The hard part of welding is finding the proper filler material so that there's no contrast between the welded area vs the non welded area after bluing. Sometimes small slivers of frame material have to be shaved off the inside of the grip frame. Deep pits anywhere on the barrel should be of great concern. I've never had to restore a badly pitted barrel exterior. I purposely don't pick junkers with bad bores or badly pitted barrel exteriors. Too chicken! I have to test fire my restorations.
