here's alittle idea Ihad for the hammer in my qb79 model. I was using the washers to shim the spring. This idea came to me one night while I was working on my gun. I had a old safety button laying around from a cracked trigger housing. I chucked it into my drill and removed a some of the metal from the top, and removed some from the safety stem. I also removed about 1/4 of a inch from the hammer spring guide, to keep it from binding and not cocking. The item I made is circled in the picture below. maybe soem of the other tuners might find this useful. Instead of using three washer, I use just one, and the small top hat for the spring.
