I bought as my duty gun in 1995, carried it for 2 years as a duty gun. Which is where the first 10 came from.
After that i carried concealed for 8 years. Over thos 10 years it works out to about 100 rounds a week. At 50k i stopped counting, which was 2008/2009, it seemed to have proven its reliability. I have put about 1k through it since 2008/9. After it i carried a fn 5.7 till first part of 2011, after that dan wesson guardian for a year or so. Now i swap back and forth weekly if not daily between a dozen pistols.

I used to have a photo comparison of my 95/6 usp40, grey box usp 45, and 2016 usp 9 tac. With all the parts apart. When my 2013 mk23 gets here i will do another one for you all.

There have been plenty of glocks with 5 times that number of rounds.

In summary, if you have the coin to shoot a brand name polymer pistol (or any pistol, for that matter), to failure you have spent multiple times what the pistol is worth in ammuntion - or you have gotten the ammuntion for free from work.

Either way, pistols are consumables at some point - but a point few of us will reach.

Its still prudent to have a spare - be it identical or just a backup. Because things can and will break - maybe not to you personally, but all mechanical things can and will fail.

Thanks for the example of the USP40 DSgrouse. Impressive feat!

Design work on a new family of pistols commenced in September 1989 focused primarily on the United States commercial and law enforcement markets. USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM) and which would later result in the Mk 23 Mod 0.[3] The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993[3] with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9 (using the 9×19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP).[3] In contrast to the ambitious and innovative P7, P9S, and VP70Z designs, the USP uses a more conventional Browning-style cam-locked action, similar to that used in the Hi-Power - but with a polymer frame.[3][4][5]

quote:

One of the most significant features of the USP is the mechanical recoil reduction system. This system is incorporated into the recoil spring assembly, located below the barrel and consists of a heavy, captive coil spring around the guide rod. Designed primarily to buffer the slide and barrel and reduce recoil effects on the pistol components, the system also lowers the recoil forces felt by the shooter up to 30%[citation needed]. The USP recoil reduction system is insensitive to ammunition types and does not require adjustment or maintenance. It functions effectively in all USP models.[6] Using this same recoil reduction system, one of the related H&K Mk 23 .45 ACP pistols fired more than 30,000 high pressure +P cartridges and 6,000 proof loads without damage or excessive wear to any major components. Abuse and function-testing of USPs have seen more than 20,000 rounds of .40 S&W fired without a component failure. Milspec environmental tests were conducted in high and low temperatures, in mud, immersed in water and in salt spray. In one particular test, a bullet was deliberately lodged in the barrel and another bullet was fired to clear the obstruction. The barrel was successfully cleared with only minor structural deformation and continued to produce consistent groups when test fired for accuracy.[7]

Testing
As the USP was developed at the same time as the SOCOM MK23, the pistol underwent much of the same rigorous testing. The barrel is cold-forged from chromium steel for increased life. USP barrels post-1994 use a polygonal profile, whereas 1994 and earlier models utilize traditional 'land and grooves' rifling. 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 4 inches at 25 meters.[16]

Temperature testing required the USP be frozen to −42 °C and fired, frozen again, and then be heated up to 67 °C and fired. These temperature tests were continually repeated with no adverse effects on the USP.[16]

The gun was also subjected to NATO MIL-SPEC mud and rain tests, which were passed without difficulty. Water immersion and salt spray also presented no problems. German Navy combat divers have used the USP for two years without any signs of corrosion.

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 hard surfaces without discharging. The USP surpassed these commercial requirements, as well as German Army and police tests, including repeated drop tests from six feet (1.8 m), 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 breech proved unsuccessful.

Testing with a variety of ammunition proved the USP meets these high standards. During the USP testing phase, it was shown the recoil-reduction system reduces the force on the USP grip to approximately 300 newtons (67 pounds-force). Peak force shock on competing .40 caliber polymer and metal framed pistols was around 5,000 newtons (1,100 pounds-force). The primary benefit of low peak shock is a decrease in wear and tear on pistol components, a great concern with the +P cartridge in 9 mm, .40 S&W, and .45 ACP. Reduction of peak shock forces also contributes to softer recoil for the shooter, although these "felt recoil" values are much more subjective.

Grouse its posts like yours (50K thru your USP)that make me think i need my head examined for buying 2 of the same models.I have 2 USP 9C's, 2 Glock 19x's, 2 Walther PPQ's etc..
It makes no sense. I shoot a lot, but i would have to live two life times to shoot these guns out.
To the original post, I wont say i kill guns with hard use, but I have thousands and thousands of rounds collectively thru these pistols, and see no real signs of wear.

Any idea on how many rounds it will go without failure running FMJ? Sorry for all the questions, not everyday I run across a reliable source who has 50k of .40 through a gun....with no spring changes or breakages.

Id argue that a lot of .40 guns wouldnt run 50k without issues. Just my opinon. Im not even close with any gun I have. My highest would be a Sig 226ST in 9mm that im pushing close to 20k on. It pretty much retired these days.

IIRC there was an ammunition company which had a USP 45 that had over 200,000 rounds through it. They changed the barrel and recoil assembly a few times.

As I remember the story, they contacted HK with a question and HK was surprised at the high round count. Great pistol that I dont worry about wearing out. Regards 18DAI
