Many years ago I got the crazy idea to skeltonize a Handi Rifle hammer to speed up lock time. I bought a couple hammers from Gun Parts so if I screwed one up, it wouldn't be a great loss, I soon found that I couldn't drill into one of them so I put them away for a a future day. Well that day came and rather than drill in a bunch of holes, I ground it out and reshaped it like the hammers on one of my S&W revolvers.
Since the Blackout was in serious need of a trigger job, I went ahead and installed it tonight. I planned to weigh it on my super accurate powder scale but it was too heavy for that so I had to settle for my kitchen scale. The best I can say is I took off 4 grams. I'm not sure if that much will speed up lock time but I like how it looks.
The trigger job I did as part of the hammer swap wasn't as good as I hoped. I was going for sub 2 pounds and I think I only reduced it to around 3 pounds. It's still a decent improvement, but I know I could have done better.
The work on the hammer took about 2 hours and another 2 to do my first H&R trigger job...
