Is Sig a German gun or a German/USA hybrid? I handled a Sig at a gun shop and saw on the frame "Frame is made in Germany". Where are the barrel, slide and other parts made? Where's it assembled? I read on the forum the newly introduced Sig pistol models have some quality control issues. Are the newer models (i.e. P229 E2, P226 E2) of comparable quality as the older models? Thanks.
