I got my friends p3at here and decided to do a detail strip of his it for him. I got it pulled apart cleaned up and lubricated. I got it all put back together and the trigger bar wont set right. Obviously, it is supposed to lift up the side of the inside of the frame connecting at the bottom of the hammer. I know I am not missing any parts, And otherwise, it functions correctly. I checked with the assembly drawing on Kel tecs website and all seems right. When I flip the gun upside down and pull the trigger forward, it will reset and fire. When I cycle the slide, it resets the hammer, but does not reset the trigger. It's like the trigger bar is falling down and not being pushed up. What keeps it from falling down? I have also found that if i slam the bottom of the pistol on the table, the trigger bar lets go as well. What did I do??? Or not do?
