The first question is where SHOULD the bolt be dropping?
That's dependent on how Colt designed it.
The 1990's Colt "SF" frame small framed revolvers dropped the bolt almost instantly after the cylinder started to rotate.
I haven't heard how the new Python is intended to work.
If the bolt is intended to drop into a leade and it's dropping early, it would require return to Colt for correction.
I "think" (note the qualifier) that the new Python bolt is operated the same way as the Mark III and later Colt's and the S&W.
These designs operate by a lug on the front of the trigger pulling the bolt downward then releasing it.
I assume the new Python uses this system since it's easy to build and works very well.
If the bolt is dropping too soon, either a new bolt or new trigger would need to be fitted so the bolt stays down longer before being released to pop up.
