A poster was bragging about his marksmanship and said "I could hit your skull from 100 yard with a 9.9". I have asked several times what a "9.9" would be. I have been shooting for 50 years or so, and have been a student of firearms for as long. Despite that, I have very little experience with 9mm handguns. I thought it might be a Tokarev, but he hasn't answered. Any ideas?
