I just bought a Walther LP400 from Tone. Lovely gent. He had the pistol serviced by Walther at a recent event in the U.K. Apparently they send tooled up service engineers to a number of uk events where they will carry out repairs and servicing whilst you enjoy the event. I'm not sure how you find out which events and when, but certainly worth investigating. Obviousley if you have a failure and want it sorted, it's not so convenient, but worth a thought!
