For the last 20 years or so I have used a 6" Colt Python and 180gr. HP's for deer hunting and it has served me well; however I would like to retire the gun from further use and just keep it as a collectors item. I am thinking of buying a 6" Model 57 S&W 41mag. or a 6" Model 686 357mag. What opinions do you forum members who own these guns have about which one to choose? I will want to use 180grain .357 and 210grain 41mags. The gun will have to be very accurate or I won't own it very long. Please advise because I want to purchase one or the other soon.
