You know, I agree with you, but on the other hand I'd never trade my NMA bored down (?!?!?!?!?) to .36 caliber for a replica Navy Remington. It's been a dang good companion, I've carried it many a mile in the mountains without undue stress on my belt, and that long NMA cylinder packs a lot of powder behind a slug, it's a good powerful gun, and "superbly" accurate. I'd love to have the "correct" replica of the Remington .36, but I don't think I'd trade my NMA of Navy caliber for one, I'd want them both. !!!
However, since the oversize version of the Remington Navy is a nice gun, accurate and powerful, and handles well with the shorter barrel, I don't think the chance is good that people will stop buying them.
But I see where you are coming from.
