Ha! I'm glad to hear that. I got up to prototype #7. I thought I did a decent job mirroring the factory design, but I noticed I could get it to follow occasionally. I assumed I had screwed up, because no way would factory hammers follow .... So this vindicates me.
Yes, I fixed the following issue. I also fixed that sometimes if you cock it with your finger off the trigger, the hammer would sometimes stick on the trigger without fully engaging the sear, so you had to touch the trigger to get it to pop into proper engagement.
