These frame mounted firing pins are at least partially inertial pins in that the hammer strike doesn't just push the firing pin forward, it drives it forward similar to how a 1911 firing pin works.
While not the same system, the firing pin is going to be driven forward as far as it physically can be by the hammer-transfer bar impact.
Probably a more accurate estimate of hammer strike is to use a little tool I used to make sure firing pins were operating properly.
This is simply a short round piece of metal like brass or aluminum dropped down the cocked guns barrel, the muzzle pointed straight up and the trigger pulled.
You can be certain the firing pin is functioning and estimate how hard from how high the metal rod pops up out of the barrel.
I made these from short 1 inch or so aluminum and brass rods with a piece of thin rubber glued to the end to protect the firing pin.
Which metal to use depends on the type of gun. A striker fired gun might require aluminum, while a 1911 needs heavier brass.
You can get a pretty good idea of the power by observing how high the cylinder pops up and you can compare a known reliable gun to a suspect gun.
This is also a test to insure the firing pin is actually working, as example to test a Series 80 firing pin lock to make sure the frame assembly is installed correctly and is unlocking the firing pin.
In the case of the new Python I haven't heard about much trouble with ignition that wasn't related to very early production, so I wouldn't worry about it.
Bad ignition is something to get interested in WHEN it starts happening.
The Colt revolver frame mounted firing pins are hardly new technology, so unless the pin breaks, gets badly fouled, or the mainspring goes weak they seem to always work.
I don't see the new Python being any different.
