Q:  What does "refurbished" mean and are these real P7s?

A:  Yes, a "refurbished" P7 is still a P7, they usually Police or Military trade-in pistols that either HK or some other armorer has recertified/cleaned and put on the market for sale.

Refurbished P7s on the market

There has been a recent flood of P7 PSP (Flush Magazine Release) pistols to hit the US market, imported by PW Arms of Redmond, WA.  These P7s were formerly in use by the German BMI Police agency and have been retired.  They vary in quality from moderate holster wear to like new.  Click on the pictures below to see what the markings look like.  These pistols range in price from $650 - $850.  The consensus is to buy cheap, and then hard chrome them.

There have also been some P7M8s on the market that have been refurbished.  These are usually readily identified by their trademark "purplish" slide and the infamous "grind" mark removing the German police agencies logo.  Here are some pictures to help identify these.  These pistols range in price from $700-$900.

The only other refurbished P7s that I'm aware of (not police trade-in from US agencies, which generally are not remarked or mutilated in any way) are some C.I.A. marked (No, not the Central Intelligence Agency, but rather Century International Arms) and some pop up for sale now and then.

Heckler & Koch has also imported and sold some P7 BYP Refurbs.  Here is a picture of one:
