I noticed something today while I was working on a couple of Springfield Armory Mil-Specs. The hammers have an extra hook above the half cock notch. Anyone else ever notice this? Anyone know why they are there? Also the stock hammers have the deepest half cock hooks I've ever seen. The actual sear engagement hooks were not in bad shape. Fairly square and about .025 and only needed to be cleaned up a bit and polished. Sear and disconnector were not all that great. They needed a lot of work. Just thought that was interesting about the extra hooks.
