Hello all. I have a model 10 predator i bought second hand a year or so ago and have been shooting it more lately. I have noticed if it is on 1/2 Saftey and you pull the trigger it binds up the safety and when you push it forward to turn safety off the firing pin falls. On full safety this does not happen. At the half safety mark it happens every time. I am wondering if someone polished the trigger and sear causing this issue. Any advice?
