German Sigs have no Swiss made parts. The only Sigs made in Switzerland were the early 220, 225 (P6) and early 210's and will be marked Montage Suisse instead of Made in Germany. The Sig Pro frame was manufactured in Switzerland for a short period of time. I own W. German, German and Hybrids where either the frame or slide was manufactured in Germany. All have been equally reliable. I'm speaking about the classic P Series pistols. The only Sigs I see bringing a premium are "as new in box" W German/German 228's, P 210's and some variants of the Master Shop X series pistols. The only reason the P Series is made entirely in the US currently is because the German government has barred Sig from exporting anything to the US. They were caught funneling guns through the United States into countries restricted by the German government.
