Thanks for your kind words, and your business! Quinten is one of our newer employees, but he has come a long way in a short time and we are happy to have him on board.
Those P250s are Bolivian contract overruns, and as such, they come with two mags instead of the normal one. At the price point we are selling it at (almost $100 below regular P250 retail), it's a great choice!
The gun's place of manufacture should be stamped on the frame; the P250 Subcompact we have in stock is marked "Exeter, NH" next to the serial number. We did not look at the Bolivian guns to see where they were made.
Mec-Gar, an Italian-based company, has made OEM mags for SIG for years.
