Hi - if the above negotiations fall through, I will take at your asking price pending a brief, physical inspection. Not for cosmetic issues, but to make sure timing and lock up are good,
Thanks for your consideration.
Regarding the matching serialization of the barrel, this appears to be a USP 9 SD since it has rear adjustable and tall front sights to clear a can. It was a factory offering, but the jet funnel was added afterwards. Nice pistols! GLWS
It appears to be the box only as OP states "ORIGINAL CARTON ONLY".
Box and hang tag do appear to be in conflict as box is 28g and hang tag is 410 bore.
