I've always been skeptical of horn striker blocks. Never have used one, but I can't see how the horn block would have the mass or the resiliency to adequately soften the firing pin blow.

Again, I could be wrong and have no experience with horn used for the purpose. I do know that some of the old Brit doubles came with a horn striker block, so somebody must have thought horn was adequate.

I am fully confident in my brass de-cocker.

By the way, when the end of my de-cocker gets pretty messed up from multiple firing pin strikes, I just dress it back flat with a mill file.
