HK USP 40 Jams

niklasal · January 2002

I was thinking about getting one of these but I have heard a lot from local officers that it has some jamming issues in 40 s&w. One of the local precincts even switched back to their Glock22's at a loss. Sound familiar to anyone?

My USP 40 feeds anything except steel cased Wolf ammo.

My USP 40 digests anything except it consistently fails to extract with steel cased Wolf ammo.

Wolf ammo is lacquered to resist rust; once fired, the lacquer softens & will make case extraction difficult and can also lead to lacquer build-up inside your chamber.I've never had a jam in my USP .40; I've shot maybe 6000 rounds in the 18 months I've owned it, factory & (mostly) handloaded ammo.

I use my USP40 for IDPA and have never had a jam or misfire.
