My aunt has an old S&W Model 38(no dash) Airweight. The only issue is the nickle finish is peeling bad(mostly on the side cover and on the frame behind the yoke). Other than the looks, it performs flawlessly. I know the Airweights were aluminum, and not to use +P ammo in them. She was wondering if it would be worth it to have the nickle finish redone? It does have sentimental value, as it was her late hubby's backup gun when he was with the PD.
