I don't really care for the no lug half lug models. Some guy goes over to Europe and buys them in bulk for two dimes in the dollar imports them and puts them on GB and try to make a killing. You don't know what they have been through or how many owners they have had.
Korth owners like to bash the Lollar Korths for no good reason. They are very wonderful hand fitted revolvers made out of the best of materials.
As far as not satisfied I already have a 4" Mongoose that I am very satisfied with. It is a wonderful revolver and would rather have it than a beat up Ratzenberg model. But that isn't what this thread is about. I was looking for opinions between Lollar Korth and Chapuis MR73 from people who own both as I am looking to get a 5.25 vent rib Mongoose or a MR73.
And that is what you got - plus free advice based on personal opinions based on first hand experience. After all, this is a discussion forum and we all are free to discuss even adjacent options and bring them into the discussion.
By the way, the guy importing the Korths and offering them in large numbers on gunbroker is not buying them for two dimes to the Dollar; he pays top-Dollar. I know that for a fact because I follow his buying and he isn't even importing them under his own FFL08 but has to pay a German gun dealer and export freight forwarder a handsome amount, airfreight, customs broker fees, customs duty, FFL08 and marking fees.
I agree that his Korths are just "merchandise" for him and sincerely doubt that he can check them each and assure full function, as some others without doubt do.
FWIW, I have been to both Korth factories and am fairly well aware of the different subcontractors they have used. Based on first hand experience I, as well as BAC, recommend the Chapuis Armes MR73 over a Lollar Korth. Handfitting in Lollar is at a minimum, they started as an factory making precision parts for Italian luxury sports cars and do so on top-notch CNC equipment.
The detour in mentioning Korths built between 1969 and 1975 is based on my personal experience - and preference - of handling well over 50 Korth revolvers and having done some substantial research on them.
