Thank you sir for that info. I shall have to contact Jerry!
My pleasure. Jerry had it across the country pretty quick. I was very pleased with his service. The area to be filed is marked with toolers dye by Timney but not the depth. The depth that it has to be filed is substantial. If you lay it together before filing you can get a good idea how much. Get it close then remove small amounts with frequent assembly checks. When it is to the point of the safety engages/disengages with effort, polish it (1000 grit) from there to get "the sweet spot"! Kit comes with another spring for very light pressure. I used the original spring and have my pressure set to 3.5 lbs.
