I see no reason to deal with the expense of a Python. A good 686 will do everything needed. A pre-lock 686 is preferable to current versions which have an internal lock. One other gun to consider is a Ruger GP100, which is rock solid and has no internal lock. I dont even think its possible to wear out a GP100, but Im sure that some people are trying. The Rugers slick up with wear and compare very favorably if not superior to current production S&W particularly in terms of durability.
