I love the old Korth, though I don’t have one (yet) but I find the Mongoose too modern / tactical to my liking.
I have a 2007 Chapuis made MR73, it’s a beautiful gun, finish is flawless with a very deep blueing. It’s also very sturdy and I’ve put a good amount of full load .357 Mag trough it without any trouble. Truly the best France has to offer (and I am German).
