Greetings. The trigger on my factory (except for a mag release change and a grip plug) Glock 35 Gen.3 is starting to drag and feel gritty. After 3500+ rounds it is requiring that I disassemble the rear trigger mechanism and clean it after every time I shoot it, or the trigger drags to the point of not resetting. I have narrowed the issue to the CONNECTOR which when even slightly dirty drags on the trigger bar unnecessarily hard. It also seems like by default there is too much pressure being exerted by the CONNECTOR, but I am unsure as this is my first Glock. Questions: 1) Does the connector need to be replaced periodically? 2) Is the angle of mine pictured below correct?
