I set up an old 1911 barrel in my mill and cut the rear hood extension, then squared up the sides of the hood. I then did a cut on the bottom lug. Everything turned out fine.
My question is the bottom barrel lug vertical area, referred to as the vertical impact surface (VIS). I understand the horizontal area of the lug is what both times the unlock sequence and raises the barrel into the slide locking lugs. It seems to me the VIS is a stopping/limiting mechanism. Correct?
Therefore, can someone tell me if the VIS acts mainly as a limiting factor to stop slide/barrel travel? As I understand it, when I begin trimming the lower barrel lug, I should stop metal removal when the manual saftey can be engaged into the slide recess. At this point no more metal should be removed from the VIS.
If I have lug drag present on the barrel/slide lugs, I would dress or lathe cut the barrel lugs until drag is no longer present, correct?
