P22 Back from Repairs

I noticed problems with slide wear on my Walther P22 and returned it for a fix. It took 3 weeks and the repair order said they replaced the barrel and fixed the bolt stop. They also included a note that the wear was typical. I don't call this typical. Called and was told that the pistol slide was zinc and I could expect this. I"m not a happy camper.

I asked about the barrel and was told that they check them over completely and fix any problems they find. Wonder if the barrel had anything to do with the fact that I don't shoot this well. Decided to take matters into my own hands and do a bit of polishing. Interesting pistol to take apart.
