I have one I might consider selling. 4 5/8 stainless though. But it's kind of a special case: I hand picked it after going through all the dealer had; I had David Clements add a cylinder bushing, so now the cylinder gap is 0.0025" with zero endshake. There is no barrel constriction, and the gun does not lead at all. I gave it a brushed finish and trigger job, and filed the front sight to regulate for a 250-270 Keith at 1000 fps. Let me know if you're interested and I'll take a few pics.
Thanks,
Pete
