My current S6 is an homage to my FIRST centerfire revolver that I bought working my first 'real job' at a LGS when I was ~17 in 1974/75. Had to get my Dad to obtain the purchase permit for it (the law back then) and do the paperwork.
At the time, the most sought-after .357 in SS was the S&W M66, but were almost impossible for LGS's to obtain due to large LE orders. We sold a LOT of Ruger S6's in SS because of that.
I immediately put one of the few aftermarket grips on it, Herritt's 'Shooting Stars' in Walnut.
I soon began reloading for it along with another slightly older young fella that worked there and also had a S6 in blue.
Young and dumb, we were concocting .357 ammo that I'm truly embarrassed to think about. We were intent on making our .357's into .44's, regardless of good judgement. The Rugers held up admirably.
I actually traded my S6 to an acquaintance for a S&W M28 6" so I could keep on exploring nuclear .357 ammo.
Anyway, finally dropped that dumb stage of loading stuff you shouldn't.
Some years back, found an identical S6 4" SS just like my previous, s/n showing it was from the same year.
Yes, I'll always be a S&W guy, but greatly enjoy my S6. It's often my woods walking gun and by my side on many deer hunts.
IMO, worth your payment is that the S6 was one of Ruger's very best designs. A K-frame sized .357 that was built like a tank, accurate and affordable.
Could never warm up to it's replacement, the GP-100. By comparison, to me the GP feels 'clunky'.
