I also own several model 36 revolvers. Affectionately known as the "Chief Special" or simply as a "chief". At one time was probably the most prolific self defense revolver around. They came in two grip patterns, round and squair. Three different barrels.. the 1 7/8" called the 2", the three inch light barrel, and the three inch heavy or bull barrel.
Some people say the three inch version is rare. Thats not my experience. While there are probably fewer three inch than two inch, the three inch versions are hardly rare IMO. My wife carries a three inch bull barrel version. I carry a two inch round butt version. An interesting side note is that for about 10 years the NYPD authorized the three inch bull barrel squair butt version as the uniformed service revolver for female police officers.
I purchased my origonal in 1974 for $115. A 2" round butt chief. I carried it off duty, in plain clothes, and as a second gun for 25 years. During that time I've qualified with it three times a year using +p ammo. While it does show a bit of wear, it still had it's origonal blue and shoots as well as the day I bought it. As with any firearm if you take care of it, it will take care of you.
Sadly there is less and less aftermarket stuff available for the gun. A 36 being a blued gun does requite a little TLC every now n then. Wipe it down after every carry. I use a silicon rag. Every so often take the stocks off and wipe down the frame under them. More often with rubber stocks. The optimum advantage of the 36 is it's miimum size. IMO putting oversized grips on it defeats this advantage. If your going to increase the size you might as well get something with more than 5 rounds like a "K" frame or a colt "D" framed revolver. The slight grip on the 36 is not a new problem. I and may others found the soloution is to add a "T" grip adaptor. This is a finger grooved device that fits the front of the grip and fill in the space between the front of the frame grip, and the rear of the trigger guard. If we felt we needed something more of a sticky surface we'd wrap a hald dozen rubber bands around the grip. Remember for most of us the gun is a tool... not a fashion statement.
