More than likely I'm just late to the dance. But, I'm curious if any of the SMEs or others think this is just an answer looking for a question.
I will say that I had some nosedive issues (which others thought strange) with the CZ P-01. But, I am way to un-informed to know if magazine taper, spring strength, dirty etc were the cause.
