Its a unique and offensive designed handgun and a nice addition to anyone's line up.

Still one of the most accurate pistols I've ever shot.


They're a good addition to the collection.

Impact Guns has them for $1850

Buds used to have them at $1700.  I'm betting you could get one from them for $1750

Used you can find them for $1600 or less.

The price only got crazy when HK kept announcing they were quitting production.  BUT HK never did stop making them and the price came down.


Most of the folks that buy one new hardly ever shoot it.  I bought both of mine used, shot one and saved the other.  Traded the one I shot on the EE.  Kept the other.

Buy one used and save a bundle.

for the Mil.?  Extreme reliability and accuracy.  Used for dog/sentry removal when suppressed.  Not really used anymore by SF guys.

for the civi?  same reliability and accuracy.  Novelty of owning the first/only pistol designated as an offensive weapon by the US mil.

Accuracy-wise, I would put the Mk23 above the USP tactical.  I think the USP elite might have a slight edge over the MK23.  I don't own a ransom rest so it's a bit more difficult to tell.

It's a good gun and no doubt a collector's item, but the main things it offers (long sight radius, extreme reliability) come at a pretty stiff premium. I had one years ago back when they still came with the marine finish. I liked it, but I eventually sold mine and replaced it with a regular USP Tac. The Tac did everything the Mk23 did for me in a smaller, easier to use, cheaper package. And then I dumped my USP Tac for a HK45 Tac.

As a suppressor host the 23 is hard to beat though. Its just too bad they are so expensive and so old school.

I'll sell you mine with the holster and mag carrier.  I've found a Wilson combat that I want and I need some extra cash.

I was issued one of these things, we had them until about 2007. We never got the cans tho.It shot nice, but man is it huge. The only holster issued was this ridiculous blackhawk nylon POS with the 2 leg straps. i had a custom pancake type one made out of kydex. I carried it operationally a few times (no, never shot anyone with it), carried it locked and cocked like a 1911, but I mostly used my G-19 just for the size/weight factor. If I had access to a USP .45 back then, I would have used that all the time. We always joked that the best thing to come out of the MK23 was the USP- HK sold them to us (USP) for personal use at a discount when we went to their armorer courses. When this thing (MK23) hit the drawing board in the '90s, 5.56 supressors weren't nearly as common (or effective) as they are nowadays, and SOCOM put out the requirements for a specialized "offensive handgun". I think HK was the only company that even bothered submitting a candidate. By the time it was available for issue, (1997?) it was pretty much antiquated. The few of us who actually carried them just used them as a service pistol, especially in direct action missions, same as a sig 228, glock 19, or M9 (the pistols available to us during the timeframe when we had the MK23). With the benefit of hind sight, the command probably would have been better off with a glock 21 with a suppressor. But like I said, those MK23's do shoot nice.

Also colt entered a pistol as well based off the colt double eagle.

The USP can handle a LOT of abuse. I think HK did a test where they plugged the bore of a USP ( with a bullet ) and shot it out with a live round and the gun continued firing and functioning.

The MK23 takes over engineering to another level entirely.







Copy / Paste~

The HK USP is probably the most thoroughly tested pistol ever produced. The testing process of the USP, already extreme in exceeding strict NATO AC-225 Military Specification Standards, in many ways mirrors the regimen the HK SOCOM pistol was subjected to .

The barrel of the USP is cold-hammer forged from high-grade chromium steel, the same type of steel used in cannon barrels. During testing, a bullet was deliberately lodged in a USP barrel. Another cartridge was then fired into the obstructing bullet. The second bullet cleared the barrel, resulting in a barely noticeable bulge. The pistol was then fired for accuracy and the resulting group measured less than 2.5 inches at 25 meters.

Other less destructive tests reveal much about USP reliability and durability. Function testing a wide selection of ammunition types, one test gun fired more than 10,000 rounds without a single malfunction. That means no stove-pipes, no failures to feed o r eject; no jams! Endurance firings of test samples has passed 20,000 rounds of high performance .40 S&W ammo without any parts failures. Sever temperature tests required the USP to be frozen at -44 degrees F (-42 degrees C) and then fired, frozen again a nd quickly heated to 153 degrees F (67 degrees C), and then fired again. These temperature spectrum tests were continually repeated, and with no adverse effects on the USP.

Demanding NATO Mil-Spec mud and rain tests were conducted, again with the USP passing without difficulty. Water immersion and salt spray also presented no problems to the USP. Outside metal surfaces of the USP are covered with an extremely hard nitro-gas carburized and black oxidized finish.

All internal metal parts, including springs, are coated with a special Dow-Corning process that reduces friction and wear. Both the internal and external finishes have proved to be especially corrosion resistant. For more than two years, German Navy comba t divers have used the same process on weapons parts without any signs of rust.

Safety testing exceeded the ANSI/SAAMI requirements adopted in May 1990. These included dropping a USP with a primed cartridge and decocked hammer on a variety of surfaces without discharging. The USP easily surpassed these commercial requirements, as wel l as German police tests, including repeated drop tests from six feet, hammer first, onto a steel backed concrete slab. Proof round firing resulted in no cracks, deformations, or increase in head space. attempts to fire the USP pistol with an unlocked bre ech proved impossible.

The HK recoil reduction system (patent pending), a mechanical dual spring buffering device, is another feature common to the USP and the HK SOCOM pistol. During the USP testing phase, HK engineers discovered this innovative unit reduces the peak force act ing on the USP grip to less than 300 Newtons (66 pounds). Peak force shock on competing .40 caliber polymer and metal framed pistols climbed to more than 5000 Newtons (1102 pounds).

The primary benefit of low peak shock is a decrease in wear and tear on pistol components. Reduction in peak shock forces also contributes to softer recoil for the shooter, although these "felt recoil" values are much more subjective.

Mine is KH date coded and I love it. Wish I never sold the Wilxox Nightstalker light and mount that I bought new for $150. But the set up was such a POS, I was glad to get rid of shortly after I bought it. Now the Wilcox mount and light sell for well over a grand.
