Educated Guess: If lockup only require 90% of the trigger’s travel, the extra 10% could easily start distorting the fitment of the parts involved in the process. Over torquing a screw would be a good analogy, assuming my guess is correct.

I really didn’t need a Python, but it was there. My wife was with me, and I had spent the past year talking about the Python. I have to be very careful about suggesting a gun purchase to her.
