Every physical number the app uses, read here from the app's own data files, so this page cannot disagree with the app. Estimates are reasoned, not taken from a source: each says what it leans on, and each could be measured.
Not listed, because they are not yet records with a note each: the gun's mass layout inside the
frame and the small forces that resist the slide (stripping a round, cocking the striker, the rails), all
estimates written as plain numbers in data/glock17.js, carried over from an earlier version.
