Now I am really confused, Scott. I commented on the thread for the s/n 403 about the stamping for the USP and S/N. Now I see s/n 058 and it looks like the USP, MODEL and the S/N were stamped prior to final preparation and finishing leaving all 3 stampings weaker than they would be if stamped after all the manufacturing was done. So now my question would be: Why is the serial number stamping on #403 stronger (and showing raised metal) than the USP stamp on both guns and the serial number on #058? Thanks again.
