OK, I see what you meant. I usually refer to this (in my head) as a 'starter hole'. It would seem most Lugers have the milled stock lug cut started from the bottom and going up; the Mauser has a 'starter hole' drilled and the end mill cut goes down. That's one theory; another is that the other companies didn't extend their drilled starter holes as deep as Mauser and all the cuts were in the same direction [down].

Reading the tool marks and visualizing how they were made is the main reason I accumulate Lugers (and Mauser & Nambu & any early handgun).

I started out as a production machinist in an aerospace sub-contractor back in 1969 (the Old Curtiss-Wright plant in Buffalo; they made P-40's during WW II). Many of the old machines were still in use, and they were quite interesting to use.

Edit: My Thanks! To kurusu for catching my spelling mistake...
