Not sure if you tracked it, but were the stoppages typically shot one on the presentation or successive shots?

Successive.
My former agency has issued USP .40 fullsize and Compacts since about '99. No issues with lube or malfunctions. The only broken one I know of was a broken trigger guard on the skull of a bank robbery suspect. We did have some issues with CCI Blazer low lead qualification ammo early on. For some reason, the case heads of the ammo were sticky and would not slide up the breech face of the HKs. Wiping off the caseheads with a rag was a low tech fix. The stuff was so sticky that you could lift a round out of the box by just pressing a finger on the round and pulling it out. Has the factory rep out, but I never got a final answer as to why.
The first indication a bad guy should have that I'm dangerous is when his
disembodied soul is looking down at his own corpse wondering what happened.
Just spitballing here, but if you're using WCC for training & duty fodder, isn't it possible that some lots of this stuff have out of spec / inconsistent cartridge rim thickness, giving the extractor insufficient purchase? Any possibility at all that this could be a causal factor in these malfunctions?
Curious what the extractor tension is. On each of the six P30s or so passed through my hands, when cycled slowly they would hold a loaded 124gr Gold Dot firmly against the breach face until it hit the ejector. My beater with 80K through it still managed to do this before I dumped it. Was the spent case rim still under the extractor in your samples?
Taking a break from social media.

Not a P30, but the only ammo my P2000 didn't like was the zinc coated steel case stuff. I didn't shoot any other steel cases. That stuff would swell in the chamber and I guess it doesn't work well with stepped chambers. The gun didn't have enough oomph to overcome such, and it would jam (actually using the word correctly here) about halfway through the extraction stroke. A strong power stroke would eject the round and all was fine....nothing I needed to use a tool or specially manipulate the weapon in any way.
This happened 2 or 4 times in 1000 rounds with MFS zinc plated steel ammo.
Gt,
Any idea on MRBF per weapon? Is the MRBF so short that it's no bueno?

Relating to improper extractor tension....
Not that it was something that needed to be done frequently, but a tuned in member on HKPRO used to offer extractor radiusing services if need be for USPs, and I imagine P-Series as well. If the extractor radius wasn't right, it would lead to improper tension....replacing the spring wouldn't do anything in this case, even though it was always the first, obvious suspect.
