I have a Buck 110 Dual action automatic. It has the round button on it, I am having problems with it closing. I am having to tap the bolster on hard wood for the button to come flush with the scale. I think I have a weak spring. I have taken the scales off and tried to expand the spring to no avail. Is there some company out there that repairs these? I would like to put Sambar Stag scales on it after I do some file work to it. Appreciate any help I can get in advance!!!!!
