I inherited a .38 special Model 10 when my uncle passed away. The gun was most likely manufactured in the early 60's, and shows some pitting on the finish. The gun is more of a keepsake to me, and I have only taken it to the range once. My question is, should I get the gun refurbished/refinished? I am not concerned about the cosmetics, but would do it if it would ensure that the gun would last for generations, or if it would harm the pistol to leave it in its current state.
