I broke mine in my KK USP 40. I probably had about 6k dryfires and about 1500 rounds. It broke while dryfiring as well.

USPC firing pin

The firing pin broke on my USPC Stainless 9mm after aprox 5k rounds. HK replaced the part for free with the newer P2000 firing pin. HK customer service hinted at the fact this is not entirely uncommon, hence the redesign of the part.

Otherwise my HK has been flawless. But I am lucky that it broke while I was practicing, and not under worse circumstance.

Broken FP on a Compact .40 with LEM at around 6800 rounds. Pin was replaced with the P2000 part. I paid to have the P2000 parts installed on two 9mm Compacts as well. With these upgrades, I once again feel confident in owning a fantastic, bet your life on it pistol.

The P2000 never hard a problem as far as I know, it was just the USP's they had different designs prior to sometime before 2005.

Broke the firing pin on my AC-dated USP9 after about 3000 rounds. The gun was never dry-fired without snap caps.

This redesigned FP that you guys are talking about – is it directly interchangeable with the original one or do you also need a new FP stop, spring, etc?

For the P2000 firing pin assembly you need to replace the block, springs, etc. Big bore seems to have a good handle on it (surprise surprise), Im just trying to paraphrase what I read. If you do a search he gave a good amount of detail about it.

I broke the firing pin spring of my AG date coded 9mm P2000.
I shot over 700 rounds through the pistol.
I made thousands of time dry firing and used snap caps all the time.
I replaced the firing pin spring and while trying the hammer bite function, I observed that the trigger action improved considerably without the firing pin block and its spring. I left the the pistol as it is with a little bit compromise in safety by only relying upon the half cock intersept safety notch:D .
Regards.

I'm the original owner of a first year build KD USP40 (1993 build) with 25,000 or so rounds through it, and probably no more than 1000 dry fires, and it's still trucking along strong. The only change was the original huge magazine release to a smaller magazine release (done by HK factory in 94 or 95). No problems here. Move along citizen.
