I have just acquired my first Colt revolver. Its an Official Police .38, 4" barrel, Plastic Colt grips (are these common?), serial 790XXX in probably 50% finish although there is very little pitting and no rust. I think it would be a very good candidate to re-blue. Any comments about that? The mechanical fit and condition is extremely good; very tight action. Smooth pleasant DA, very light, crisp SA. I doubt if it has been fired much more than a box or two of ammo in its life. I have not shot it yet myself, but plan to later today or tomorrow. Can anyone tell me when it was made? I paid under $200 for it. Did I get a good deal, or was I bilked?
