Not to knock the Smiths, but there's nothing like a Python.
Have you had one go out of tune that quickly?
How about the King Cobra (and probably the Mk IV and V)? They seem to get lots of mixed reviews when it comes to timing. What's your/shop experience with King Cobras with timing problems?Don't get me wrong, the Python's a very nice revolver, but the Pythons (and Colt revolvers in general) are so shrouded in mythos and rumor that it's easy to overlook their faults.
