I own a QPQ in .40 with a stainless slide. When I bought the gun I was told the QPQ was the designator for the stainless. Now all I see are the titanium.
So,
1) What does the QPQ stand for?
2) Are they still making the stainless steel upper?
3) Is my stainless a coating like the titanium or is it truely a stainless steel slide?
Thanks.

I'm sorry to be the one to burst your bubble, but the QPQ is NOT stainless. QPQ stands for Quench, Polish, Quench. Meaning they take the slide and Quench it in Tenifer then Polish it, then Quench it again. It isn't stainless, just regular steel.

Here's the statement from Walther themselves on the QPQ:

The new processing technology for the QPQ allows the choice of a silver coloured slide while retaining all the corrosion resistance and durability of the tenifer-finished, hardened steel. The exclusive Walther process advances the state-of-the-art beyond stainless or nickel plating. Test conditions of 20,000 rounds continuous firing, demonstrate significant resistance to wear.
