Owning both an older 6” blued Python and a newer 4.25” SS Python, there is a significant difference between the two with regards to how the triggers feel. The older one has a much lighter and smoother trigger but where things are really noticeable is shooting them in double action. With the older Python, as the trigger is pulled and the hammer comes back, there is a noticeable click’ before hammer falls. This feature is nonexistent in the newer Pythons. That said if given the opportunity, I’d still buy a new 4.25” blued model just for the appeal factor.
