I have a S&W Model 28 which is a 6" Revolver on a N frame. It is also known as "The Highway Patrolman" which is engraved in gold on its side.It has a Bomar Rib for a sight ,a target trigger and the large target grips. It is the finest and most accurate handgun I have owned. I also have a Colt Python and my wife has a new 640.They are both nice but the 28 is still my favorite.I bought it from a friend of mine in 1976 and it was almost 20 years old then.
