That's a good looking pistol you got there NARC.
That chatter on the feed ramp is a little troubling, but I am betting you can smooth that right out. I would put several hundred rounds through it first and see if you have a FTF - I am betting it's the stock mag and it won't do it with the aftermarket ones, but you never know.
Other than that, for $900, I think you got a pretty sweet looking piece of kit there.
Looking forward to your range report - if ammo ever comes back to available again...
