When my dad passed awy last May, he left each of his kids a little something. Not a ton, but a nice little "remembrance". I was able to get 2 things with that money. I got a Tikka 30.06 and a new Colt Python 4". Does anyone else have one, or have any experience with them? I`ve yet to shoot mine, and hope to remedy that very, very shortly. But I`ve read that the rear sight is suspect, and should be replaced. Wilson Combat makes a replacement rear sight for this revolver, but I wonder if I should just go ahead and get the Wilson Combat replacement, or shoot the danged thing and see how it holds up before I go making changes. I would have liked to keep it "original" if possible. What do you think?
