    What is meant by this 1911 term?

    I'm selling one of my 1911's and someone asking for pictures of the "VSI".

    should be VIS = Vertical Impact Surface
    some people are looking for the "bowtie" cut to the VIS

    here's a photo of the VIS area (non-bowtie).

    +1 on what Quack posted.

    Are they also asking for a picture of the back of the barrel's feet? If they aren't, then they only know 50% of what to look for.

    If the lower portion of the barrel feet slams into the frame too hard, they may brake off in the long run. The higher up the barrel impacts on the bowtie cut, the less stress is put on barrel and feet.
    Most frames are born with a relief cut, but if it's missing, the quick fit is to file a slightly negative angle on the barrel feet. This way the impact area is moved futher up, and the momentum and stress will be lesser.
