There is C96 shooting video in slow motion posted on youtube.com. In slow motion, it's obvious that sight leaf flying up quite high while the gun is fired... I think that's too high.

The video poster (forgotten weapons) did not present the pistol details. But I bet it's a "reblued, mismatched, etc, etc" -- there is a implication: the sight leaf spring lost its strength on that gun. That would explain why the sight leaf flying abnormally high during firing. Repeat dropping sight slide on steel, the sight button is expected to break soon.

Is there a gunsmith device that can be used to measure how much forces needed to raise the sight leaf by certain height relatively accurately? Collectors usually pull the sight leaf up to get a feeling of sight spring strength which should match the condition of a nice gun (say, too weak is abnormal). That's the feeling on their fingers, works for inspection purpose but not very scientific. This area deserves some quantitative study.
