I am the second owner, so I cannot tell you how many rounds are through it. 5 mags have been put through by me.
It comes with 3 mags, a Serpa and 2 single mag holders.
There is a small mark by the front sight, but it is not through the finish. There is also a spot on the left side from holster wear. These are NOT major, just trying to be as accurate as possible.
This is a great pistol, I am just selling it off to scratch another itch!
