Anyone else out there have some experience with the Korths and what are your impressions?
I've assembled a medium-size horde of the original Ratzeburg Korth revolvers at this point, but I don't own any of the new Lollar Korths. The latter are very fine guns, but I'm really only interested in owning the Ratzeburg models. I've been able to examine and briefly work the action of the newer Korth National Standard (imported by Nighthawk as the Mongoose) belonging to a friend, however, and I should be able to shoot it soon. The action felt much the same as on the original Korths.
To me, the feel of the Korth DA trigger is the best there is, rivaled only (for me) by that of the Manurhin MR73. (Disclaimer: Haven't yet fired a Janz, but the Janz action is basically that of a Korth.) The travel is definitely shorter than what shooters of American wheelguns will be accustomed to, but it's incredibly smooth, owing to the interchangeable roller wheels on the trigger that engage with the double-action sear. It's actually also a bit of a misnomer to refer to the Korth DA trigger in the singular, given the range of adjustment that's possible. The Ratzeburg models shipped with five interchangeable rollers providing for various levels of precise stacking in the DA trigger pull; the smallest roller provides for the heaviest stacking with a clear staging point, and the largest provides for no stacking at all. (At some point in the 1980s, after Willi Korth had given up ownership of the company, Korth began shipping the guns with three rollers instead of five.) The trigger pull weight is also adjustable via an external adjustment screw.
The Lollar guns preserve both the interchangeable rollers (I believe they ship with three, like the later Ratzeburg guns, not the original five) and the ability to adjust pull weight externally. Maybe you'd just never warm up to a DA pull as short as that of a Korth after shooting revolvers with longer pulls for so long, but it's possible that there's a combination of trigger roller and trigger pull weight that would produce overall trigger characteristics more to your liking.
I know some of the original Korth models had some adjustability in the trigger...but I don't know if it was all models or just limited.
Only the first series of the Korth Sport (the 21xxx series, produced in 1965) lacked either of the two manners of adjustment described above. The trigger pull weight became externally adjustable with the 22xxx series (1967), and the action featuring the interchangeable trigger rollers was introduced with the 24xxx series (1969). All Korth revolvers produced from that point forward featured both the roller action and the external trigger weight adjustment screw.
