Just for giggles, I mic'ed my three grip frame 'abutment' widths, at the point of most wear...

S/42 = .255"
6782 = .250"
86434 = .253"

Interestingly, the 86434 shows no imprint of breech block or toggle 'lip' marks (it's a commercial 7.65 cal)...and the 9mm S/42 (pic somewhere above) with the sharpest breech block impression measures the greatest width...

I can't find a dimension on the blueprint, so I don't know if these are just tolerance variations or 'hammering' changes...
