I have both, a Single Ten, and a new Single Six. I prefer the thinner "Gunfighter Grips" that the Single Ten comes from the factory with. I know I can get the ST grips thru Ruger parts, but thought Id throw it out here and see if I could help anyone out, if they wanted the thick style grip, and help myself also to get the thinner grips. The SS I have is the newest style, with the laminated hardwood grips, just like the ST has. They are in perfect condition. I would need your Single Ten screw, and the Aluminum spacer that is between the grips(the spacer is there to keep the grips from cracking if overtightened, because they are thin in that area). You will get my grips and the screw for the Single Six(longer screw, for the thicker grip). There is NO spacer for the Single Six grip, because it doesnt require one. I have swapped them, on my 2 guns, and they are a perfect interchange. Here is a picture of my SS and the grips it has, so you will see what I am offering.
Please, I want perfect condition grips, and you will get perfect condition grips. Thanks.
