FWIW:
I'm in agreement with the folks who believe you actually bought a surplus (imported) Lower Saxony Police HK P7.
Having said that, I'll agree that $1000.00 is a couple of hundred bucks too much (in the present HK P7 market), even if it were an "A" grade (I'm guessing the label on the box should tell you the grade, unless it had been removed previously by someone before it was put in the glass case for sale
), but if the pistol shoots to your satisfaction and you are happy with it, just shoot and enjoy the sucker.
Two hundred bucks either way is not going to make you or break you, and you have bought what is, in my opinion, one of the finest 9MM pistols ever manufactured...
I bought three ("A" grade) HK P7 from CDNN three years ago when they first hit the American market.. All three were beautiful, functioned and fired perfectly, and were extremely accurate, per their reputation...
Just shoot and enjoy..
Best Wishes,
Jesse
P.S. FWIW, I'm thinking your "whatever" was imported with the past two years or so, as the H&K import facility moved from Trussville, Al. to Columbus, Ga. some time after I bought my three.
