about 30+years ago maybe 40 years ago Federal put out a Police load for the model 58 Smith and wesson. it was a 180 gr. SWC loaded to about 900-1,000 FPS, it was a very nice load in a model 57 or 58. about that's when the bigger mags came out for the 9mm's and who wanted 6 shots when 15+ were available. That was the death of the revolver for police work(except for concealed carry or hidouts) I still load and shoot the model 57's, there isn't a more accurate revolver on the market with a 6 inch barrel. yes, I know .44 special in an "N" frame is very accurate (and yes, I've got a couple of thoses too.) but you just can't beat the .41 in a 6 inch barrel or longer. and yes. the 586, 686's are very accurate nice guns. (and yes, I've got a couple of them too) 4 and 6 in. but you get the loading data for the .41 mag., load it with 180 gr. swc's at around 800-1,000 FPS and you'll be a real happy camper. use unique, or W 231, or Clays or what have you, you can't go wrong.
