Yeah, but Paul, reddit is not the best source. If you read through your link, there's a couple posters discrediting the OP who had the issue with his MR73 -- and that post was from more'n two years ago, so it wasn't one of the new MR73s. And I believe the OP was speaking to the new Manurhins. Which seem to be doing really well and have quickly established a loyal following.
The old German Korths are fantastic and beautiful revolvers. The ones made under the auspices of Nighthawk, not so much. The matte finish, ugly billboard ... yech.
I've got a beater 27 and it's a great gun. But yeah, the first opportunity I get for an MR73, I'll go for it... And wishin' I could afford one of the old Korths...
Old Dog, the older Korth Sport .22s can be had for about $2K, I recently handled a new S&W .22 priced at half that that was junk by comparison. Kind of cool to think the old ones were all worked on by Willi Korth himself.
