Got One!
This past weekend, I went to the Gander Mountain store in Lakeville, MN, to see if they had any of these "Walther P-1 Shooter Packages" in stock. This being Gander, I was fully expecting the "deer in the headlights" look from their salespeople when I asked about the package; to my surprise, they knew about it, and even had four of the P-1s in the backroom.
They brought all four out for me to examine. Three of them showed evidence of light usage (bluing worn off the slide rails and breechface, minimal handling wear, etc.). But the fourth one was brand-spanking new, with not even the slightest hint of bluing or parkerization wear anywhere, even on the breechface. A manufacture date of 10/80 was stamped on the slide, but for what it's worth, it looked like it could have been manufactured last week.
Needless to say, that particular P-1 found a new home immediately. Detail-stripping it at home confirmed that the pistol was indeed mint on the inside too.
Not a bad deal at all for $250!
