I have an opportunity to buy a model 58 in nickel. I'm not sure the dash. I understand this to be a pretty rare gun, but I'm unable to find exact production figures. The SCSW 3rd does not even list a premium for nickel but since this model was intended for LE agencies, I would expect nickel to be rare in this model. I think I read that there were only about 26k 58s made total. I'm wondering whats a good price for one WITHOUT original grips. The guy supposedly has spare grips laying around but what would be right for it? I don't know the dash, so I don't know if its supposed to have diamond grips or non diamond. Also, its supposed to have service grips, not target grips? I'm not sure if there were 6 in barrels on these? I think its a 4in. The guy that has this gun apparently wants $950, but he claims the finish is in excellent condition and its mechanically perfect. Is this worth looking into? I think the price is high but I never saw one for sale either. Help me out here, thanks.
