The problem I'm sure is the spring for the top sear.Does anyone know where I can get a spring that will work, I understand it's rebadged and sold by Webley and a few other names and the trigger assembly is almost a copy of a Gamo (horrible Spanish air guns)Hatsan only sell the complete trigger assembly in Europe, there are none in Spain or the UK at the moment, ironically a trigger assembly costs about the same as a complete refurbished Striker in the USA!!! For some reason they do not sell refurbished guns in Europe or I would have got a parts gun :|
