Details, this next one is a small thing that may not of contributed, but I will address it also. In the bottom of the recess that the sear is installed, in the area of the pivot pin I did some scraping with a burr knife. It must have been a little tight there or I would not have done that scraping. There are a couple of smooth spots that could have been made with fine wet or dry sand paper or could be wear from the sear. The sear with the pivot just above does not show any wear ,but just in case I will go in there now with a small milling cutter to make it a little deeper. You can see the angles on the inside of the corner on the trigger, I must have been at the limit of the depth the grinding wheel could do. This was a borrowed surface grinder and my boss probably would not have appreciated me dressing all that material off his grinding wheels.
