Hello fergbear. Just like Walther said...a small amount of brass flakes is normal. Without pictures, I, Walther or no one else can really comment on the brass flake accumulation in your pistol.
I certainly wouldn't recommend a complete disassembly of your pistol.
Go put another 300 rounds of the same ammo thru it. If it still produces buckets of brass flakes, take pictures, don't clean it and contact Walther.
