Unknown brand barrel toolmarks from P80 PMF pistol
« on: May 11, 2023, 11:18:24 AM »
We get a lot of barrels associated with our privately made firearms (PMFs) that have coarse reaming marks that cross over the lands and grooves, but this one was particularly coarse. It was just marked "9x19 SS" with no other brand markings. I know the "SS" stands for stainless steel in other brands of Glock-type barrels.


I was thinking a rough reaming, then they just button rifled it? I am curious to see what others think.
