Well to be clear, I have never dealt with HK customer service. I requested an email staring when a part came back in on the HK Parts website and ordered it. However, Palmetto State Armory gave me terrific CS. That is where I ordered the USP from.
I like the USP but I am certainly not in love with it. I wouldn't give up my Sig or Baby Eagle for it and (for now) I shoot my XD better than it as well (also have probably 5 times the round count thru it). But, it was a great value at 429 w three mags and night sights so I will def hang on to it.
Any other mods anyone can suggest? This will most likely stay a range gun for the immediate future as its pretty large to carry
