Ahrends Retro combat or Retro Target in the exotic wood (not laminated plywood ) of your choice. Ebony is no longer available for S&W grips ( can get 1911's) many other woods to choose from.
Order a set and have him make just what you want , nothing like a custom made set of grips.
I don't have a 586 but the model 58 in my avatar has Ahrends Retro Combats in dark red cocobolo. I specified that color and he nailed it ! The man knows how to shape them so they fit your hand .....they are SWEET!
