I have tried to limp wrist my fullsize USP. 45 over & over without success, it fires and returns into battery no matter what.
My USP Compact 9mm wants a firm platform to work against, when training women it will malfunction easily if I don't instruct on a firm grip from wrists to shoulder.
Let us know if the new RSA resolves the problem!
Looks like a timing issue. HKs high speed camera will isolate the trouble spot.

Any update on this? Did HK have any ideas? Thx
Would love to hear what HK thought the issue was/is.

Sry guys, know I haven't posted any sort of updates. I was away for the holidays and extended vacation into the new year. So I didn't get around to sending the firearm out right away. The pistol is now with HK however and I will post a follow-up when I hear from them.
Still no news to report guys. I followed up with HK today for a possible update, but there haven't been any notes/updates added to my RMA since the firearm was checked in.
Don't know if this is of any value- I have a USP 9mm that after 2000 rds began to stovepipe and fail to feed. I replaced the recoil spring, then when that didn't help, the extractor and that had no effect. I shoot almost daily because I work at range- I bought new mags..... nothing helped. I ordered new extractor (again) and spring and popped the old one out and as I tried dropping spring in the well I noticed the amazing "gunk" that had accumulated in the well. Using a dental pick I removed a huge amount or residue and once I reassembled --it was its old self. I immediately changed my cleaning routine so I no longer use a spray cleaner/lube on the slide because I suspect the spraying created the sludge. I now dry brush the slide and use a lubricated patch to wipe things down on all my guns... the 9mm now has north of 10k rounds and runs like a charm... BTW- I have 4 other HK's and many SIG's and it was a problem on all. I just removed my SIG Legion Extractor during my yearly maintenance because I was curious and the USP 9mm and neither had the gunk buildup so my changing cleaning procedures seemed to help... for what it is worth.
