Hi Guys, I am hoping you can help me out. I know the is the S&W forum, but I posted this same question on a Ruger forum, got over a hundred views but no replies. In addition to my S&W collection, I have a Ruger Service Six with a 4 inch barrel in .38 Special. It is apparently sighted in with 125 grain ammo. I would like to shoot the 158 grain ammo I use in my Model 10's. Does anybody know where I might find a taller front sight for the Ruger? It is pinned in and removable. I have tried Gun Parts, Popperts, Brownells and the Ruger website with no luck. Any help would be greatly appreciated. At least I will get an answer here. Thanks for the assistance.
