About removing the firing pins for annealing. It sounds reasonable, but my story is this: I shipped a NID receiver to Turnbull for new case colors and had stripped it clean except for the firing pins - leave it to the pros kind of thing. When I got it back, everything, pins and all, had gone into the furnace. Somewhat alarmed, I called Turnbull and their response was along the lines of, "Yeah, no worries."
