Ruger Service Six in stainless. [See below. The one below is stoked with +P+.] A very comforting presence when on one's side or in your hand. Available once upon a time in blue, or stainless, in .38 Special or .357, adjustable sights or fixed, short, 4", or 6" bbls., hammers with spurs, hammers without, etc. Different variation/configurations had different names: Service Six, Security Six, Speed Six, etc.). Sadly no longer made, but often encountered nib on gunbroker. IMO, ounce for ounce it was probably the best of the .38 police revolvers, but the timing was wrong and it soon found itself competing with the Wonder-9s for market share. The Redhawks and the GPs are descendants of these.
