I know the 686 is the darling of the 357 lovers, but this is an M stamped 1986 beautifully preserved stainless 357. Does anyone knowif these are better or worse than the newer models? I hear the ruger gp100 is more. Rugged and can take 357 loads all the time without wear where the smith is smooth, but needs more babying, ie, you should shoot more 38 through it. Any help would be appreciated.
