TG,
I don't have a dog in this fight, but I do have a question. I have seen arguments for and against several things - peep sights being one of them - when it comes to PC events. Underhammers are almost universally shunned it seems. My perspective from the peanut gallery is that the PC folks are driving the boat based on what was popularly used. If something may not have been in vogue at the time, but was available and is documented as such, why is it cast out as unacceptable? I mean, here in the 2000s, flintlocks, handgonnes, matchlocks and even caplocks are not in vogue with the rest of the mainstream (hard to believe, I know, but it is true - I read it in the Enquirer), yet there are plenty in use and a cottage industry supporting them. Certainly back in the Mountain Man era, there were fringe folks that used peep sights, underhammers, and other stuff (maybe even peep sighted underhammers...), so why would they not be acceptable?
