Weird, I've owned two P210's Legend Target and one Super Target that were date coded 2013 and they all had clean slides w/o the Sigarms Inc. Exeter, NH import marks.
They came straight from the Canadian importer (R. Nicholls at the time).
This is definitely not a pistol that was intended for the European market since it wears the US import marks. Probably a pre ban US import that recently crossed our border since it was manuf. in 2014.
