I do hope I will be forgiven for this, my pistol is not a Walther but a Smith and Wesson 99 AS. I have searched for two days trying to find some, any information as to how to clean the trigger pull on this pistol, no information was found. The double action pull has to be the grittiest I have ever encountered on any handgun, period. If someone here can head me towards a fix for this, I'll be forever grateful. Thanks.
