Writing a range report for a Korth is a bit of a different proposition. Korth's guns are so consistent from sample to sample, you get the same over-the-top reviews by pro gun journalists over and over. Korth, "The Ultimate Revolver" by Nighthawk (the Military Arms Channel); Korth Combat .357 Review: "The Rolls Royce of Revolvers" (guns.com); or, "The Best of the Best: Korth's Mongoose Revolver". But anyway, I was interested back seven years ago, and this month I just bought my second Korth, I'm really happy I did, and would recommend Korth to virtually any shooting enthusiast.

My first Mongoose was a 4", this 3" is for concealed carry. So with the opening paragraph above in mind, I'll just say that the Korth is the only revolver manufacturer I’ll EDC in place of of a semi-auto, even after massive amounts of semi-auto specialized training from a state LE agency. You’re not losing anything with a Korth .357. And you are gaining next-to-nill MTBF rates, and as useable / controllable power at the muzzle with a tame to mid-power .357 as my former agency .40 Glock. Unless you're LE or military where a running gun fight is possible, I'll also say that the need for a magazine w/15-20 capacity is generally a defensive carry myth (although an 8-shot Mongoose would be nice).

My latest 3” is again a repeat performance of my 4 inche’s accuracy, and DA ball bearing smoothness is like glass. No recoil problem with Federal Premium .357 heavy grain HP w/+600 lbs of energy. I keep the action just ever-so-slightly on the firm side as I run .357 and can consistently keep shots inside a plate at 25 yards in DA. I don't stage the trigger, just smoothly pull deliberately and with pace, and practice with double tabs. I virtually never run SA as that is a potential liability in defensive carry.

The third pic are my three S&W's which will regrettably sell. All three Smiths went to TK Custom for action jobs, but still the Korths shoot better. Significantly better. It's not close. However, the shrouded barrel R8 Smith is for sure on par with the Korths with respect to accuracy.

Interestingly, any Korth can take a second 9mm cylinder as long as the extra cylinder has been fitted to your frame. It is literally a one button drop-and-mount change. What''s crazy is Korth has engineered the 9mm cylinder to shoot 9mm rimless cartridges without moon clips. In an article later referenced in this thread, none other than Masaad Ayoob did a full Korth review and was not only stunned at the Korth's accuracy, but surprised there was no accuracy diminishment with 9mm; and he reported no load or unload problems with the moon clipless 9mm cylinder.

All modern Korths are DLC coated. DLC stands for ‘diamond-like carbon’. Aside from the aesthetic benefit, DLC coating is also harder than nitride coating, making it ideal for firearms that sustain heavy use. On the other hand, while much slicker than Cerakote, it does not resist corrosion as well but will otherwise take heavy abuse. This is why DLC has become a $275 upgrade on Wilson Combat 1911's that would normally have WC's proprietary Cerakote like protection. “The Korth’s DLC finish is smooth and even, and it stands up well to abuse. DLC is fast becoming the finish of choice on firearms that are subjected to rough handling on a regular basis. Hardness, wear-resistance and a low coefficient of friction are all reasons why a DLC coating is a great choice for a high-end gun. . . . The perfect fit and finish is a hallmark of Korth revolvers, . . . . these revolvers are hand-fit and hand-finished, the timing and operation are flawless. The hand effortlessly rotates the cylinder with each pull of the trigger, and the lockup is rock-solid.” Guns & Ammo, Dec. 2020.

Here’s an interesting fact re both my Korths, I can not slip a piece of paper between the cylinder and forcing cone, yet somehow they never touch. The cylinder gap is spec’ed at 0.003 inches. And the thing is made completely out of hardened tool steel.

No doubt $3,699 is just eyewatering for a revolver, but these purchases really ended up with no regrets. Not unlike my years-ago switch from S&W and Kimber in 1911's to a Wilson Combat CQB Elite and WC X-Tac (the latter for competition). I don’t know if a Korth is a luxury purchase in an era when the average selling price for a new light vehicle in America comes to around 48,000 U.S. dollars (Car and Driver April 2023). It just has to be worth it to you, or at least worth more to you than that lift kit, rims, and tires or whatever. Since it is my primary EDC (occasionally WC EDC X9L), it is.

Grace be with you all.

Satisfied as ever.

As mentioned above, all modern Korths are DLC coated. DLC stands for ‘diamond-like carbon’, so it isn't surprising that it gives a gun the shiny, mirror-like appearance of a crystal. Aside from this aesthetic benefit, DLC coating is also harder than nitride coating, making it ideal for firearms that sustain heavy use. On the other hand, while much slicker than Cerakote, it does not resist corrosion as well.

Picture 3 is a good picture of a the DLC coating, but unfortunately that is not my gun and comes from a web site.

I know absolutely nothing about Korth’s, except that they are pretty expensive. From what I’ve read, most folks think that they are worth their cost. I have an observation. The guns shown here, and it may just be bad angles, seem to have a more matt style finish, and maybe folks that purchase Korth’s prefer that style finish so their owners don’t have to worry about reflections. But, call me vain, if I spend that much money on a revolver, I want it to have a high polish finish! Do they also currently offer a high polish option?

Not a matt style finish, me not keeping a clean weapon. All modern Korths are DLC coated. DLC stands for ‘diamond-like carbon’, so it isn't surprising that it gives a gun the shiny, mirror-like appearance of a crystal.

Post #2 Picture 3 has a good pic of the DLC

Both of mine were around $3,500 each, but yes, overwhelmingly worth it.
 
I purchased 4 inch Korth Mongoose with the 9mm cylinder.
I have not shot either cylinder much. I have not adjusted the trigger, I liked the settings as they came from the factory.

You have some nice guns, the prices seem to have escalated the last couple years. Have a Korth .22, fun to shoot. Also have the Manurhin MR73 in .357 & .32 long. Usually shoot them in double action to keep in practice for a double action revolver league we shoot every spring. Was lucky to find all 3 with original boxes, Larry

The main spring does not allow the use of grips with screw through the center.
The Hogues, with the stirrup on the bottom of the grips, works very well and you can choose rubber or plastic.
I found that Bill Davis grips will work as the screws are under the top and bottom of the grips.

I have a 6 inch Korth Mongoose and use a Blade Tech kydex holster for a 6 inch L-Frame S&W. The DLC coating is the best -- Kydex is hard on a guns finish especially blue steel. I've done many draws and there is no wear at all -- very durable. What I don't like about the new Korth (made in Lollar Germany) is Polygonal Rifling which doesn't go well with lead bullets. Combine that with a tight cylinder/barrel gap and lead fouling builds up fast to the point where the cylinder will seize up. So my Korth requires jacketed bullets only. The older Korth's made in Ratzenburg Germany have barrels that will handle lead bullets better.
 
In 2008 a Korth Combat started at €4780 for the matte version, while the plasma plated polished blue version was €6362. Nill had made the grips for Korth since 1969 until the factory closed in late 2008 but the current price of €3275 (incl. 19% VAT) is a whole lot less than it was 15 years ago and I am not aware of other manufacturers lowering their prices at a comparable level in the last 15 years.

It looks like a dull finish to me. you're saying it's shiny?
 
does Korth make one starting with a .4 instead of a .3?

Yes, they make a wonderful .44 Magnum that is in-the-hole in my purchase plans. On deck is the .357 4" 8-Shot, then I plan on the 44 Magnum.

They make two .44 Magnums, a Mongoose in the same style as the .357 Mongoose only heavier of course; and, they make an NXR version which is over-done and over-engineered, but a remarkable gun nonetheless as pictured. The gun could be the .357, but the .44 NXR looks just like it, again just heavier.

Yes it is a relatively shiny coating, but the first two Nighthawk web-site pics are professionally lit by the photographer and make it appear a little more so than actual. The third pic is my Mongoose, and a cleaning may be making it look a touch more-so than actual.

I find that the finish of the Ratzeburg Korths is more shiny than of the Lollar - made guns. Korth Ratzeburg had outsourced the bluing and PVD coating but had polished the guns meticulously in-house. The bluing on Korth revolvers is pretty wear resistant. I had bought a pre-owned 1969 Korth in 2008 and shot it every week until a few years ago and the bluing still looks very good.
And the best part is, that this Korth is a .22 l.r., so I could afford shooting it weekly without having to sell my S&W revolvers to buy ammo :).
