It looks like these are being imported again--at least for the short term:

To be clear, these aren't the "American" P210s produced in NH (for considerably less $$); they don't use the "ejection port" lockup like the American guns. I suppose they could be leftovers from the "P210 Legend" that was produced in Germany, several years ago. Or perhaps they're new production. This excerpt from the linked listing suggests more are on they way:
THE LEGEND IS BACK. MAD DOG GUNS IS THE UNITED STATES DISTRIBUTOR FOR ALL P210'S. ALL OTHER SIZES WILL BE IN STOCK AND IN SILVER OR BLACK. THESE SHOULD ARRIVE IN 6 WEEKS DEPENDING ON CUSTOMS. I AM TAKING DEPOSITS NOW. ANY QUESTIONS PLEASE CALL 1-602-708-1725.
So... I'm thinking they may be making them again... and sending them our way again. Interesting, in the wake of those P226 LDCs that came in from Germany a few months back. Sounds like maybe someone else (besides Sig NH) is importing them? I wonder what's going on between Exeter and Deutschland.
There's several other imported P210s listed on GB, at the moment. All of the "Super Target" persuasion, some 5" some 6". I mean, I can't afford one--so, whatever. But maybe you guys can...
