Huh? What is the matter with you Python? I have a 4" that my dad gave me. The only Smiths that I have handled that come close have had a lot of work done to smooth them up.
My 6 inch blue Python is positively creeky compared to the Mod 17. My uncle's 629 .44 is also much smoother than the Python. Since the Python is in > 95 percent condition and no longer in production, I've cleaned it and have for the most part retired the gun.
Have you ever heard of a S/W Model 53? One Great Gun.
My S&W 45ACP double action revolver was a little rough out of the box, but some diligent exercise of the mechanism has smoothed it out very well. Trigger pull is still heavy but smooth, which suits me just fine.
