I'm curious what failed on the original part, and what happened for you to notice. There's been a discussion about striker sleeves failing (mine did, though it hadn't yet affected function) on PPS pistols but I haven't heard much about failures in P99's.Thanks for the help!
I called Walther Arms and ordered a replacement striker assembly. It's $91.63 delivered! But I needed it to get my P99 back into operation. Lesson learned; always use snap caps when dry firing.
I was under the impression that the P99 could be dry fired without snap caps safely.@Nova231: At best I fired 150 rounds through the pistol. I dry fired it several hundred times. The trigger was well broken in, just broke the firing pin in the process.
