Hi all, I just picked up a used PM40 with a trigger problem. At first it had maybe a 15 to 18 pound pull after take up. I took it down and the trigger lever spring had been digging into the channel in the frame. I cleaned all the plastic out and smoothed out the channel and put some bend in the end of the spring now it still breaks at 12 pounds on my gauge. (Before it was heavier than my gauge would read) I can see no other problems and I’m at a loss. Anyone with any ideas? Thanks
