Mauser Hump

Dwight Gruber · 06-12-2002, 11:07 AM

I may run into a descriptive terminology problem here, so bear with me...

I can visually compare an Erfurt, an S/42 1936 (has a "thick" casting) and a byf 41 with hump. I note that the grinding on the byf which results in the hump, puts the rear of the frame (where the toggle stop stikes it) back to the original dimension, i.e., where it is on the Erfurt.

It would take a micrometer (which I do not have) to make an objective determination.

Is it possible that the thicker Mauser casting disturbed the geometry of the pistol's operation, and they discovered that it worked "better", somehow, if it was put back to its original dimension? Grinding this back, but leaving the extra metal to retain the toggle pin, would naturally result in a hump
