Howdy, I'm a new Ruger owner and I just joined. My Dad recently gave me his SS Police Service Six with 4" barrel. Ser # 151-491xx. A square butt .357 with fixed sights. This gun was in his "crash kit" while he flew the bush in Alaska for several years after retiring from the airlines. He's 90 now and says he doesn't enjoy the recoil anymore. (He still packs, just a little smaller). I've read all I can about these beauties and intend to find a couple more around town over time. It had some minor pitting from being to long in the holster and too little used but I cleaned it up with 400 grit , 600 grit and a Dremel with polisher. It looks great. I'm hooked. It goes shooting later this week. Thanks for the forum. Alex
