Other than HKParts?

I had an odd malfunction today with one USP40, the mag release kept disengaging with each shot on one particular magazine (old used magazine).  I want to scrounge the baseplate, spring, and follower and replace the magazine body.

excellent, thanks!

No problem

I ordered it, it arrived, turns out they sent me a ban-era metal magazine body for a USP compact.

Website clearly says that SKU is for USP, not a USP Compact.  Even the wrapper with that SKU says "MAGAZINE HOUSING, USP .40" with no mention of Compact.  I'm thinking H&K might have been the ones who screwed up by putting the wrong mag body in that wrapper.  MGW issued me an RMA, waived the restocking fee, and are physically checking to confirm what that SKU actually is.

MGW confirmed: those are all Compact mags despite the labeling on the wrapper. MGW was very apologetic and are changing the website description for that item.

Crazy, isn’t it?  Here is the wrapper.
