Though not a S&W revolver, the Q is still interesting I hope. I have a blued steel revolver I want to put a 3” barrel on. I found a couple but they are stainless steel. Are there any problems mating a screw in stainless barrel into a blued carbon steel frame? It’s a blued 6” gp100 I may want to carry, Thanks to you rabid non-fans for overlooking the blasphemy. I still prefer S&W for most applications.
