Thanks Brian I had a very quick look will look in detail later the chap I bought it from was a guy who had shot in the Commonwealth games in the early seventies (not with this pistol) but it is set up brilliantly & deadly accurate & im by no means the best shot! Im sure he has done something to the trigger as mine is perfect & having looked this seems to be a bug bear for some. I realise it's nothing like the Walther version but I like it very much.
