    Default Rifling

    I dont post much, but i found something that I don't know anything about. I have been intrested in purchasing an additional usp 9mm full size, i found one on gunbroker I felt was a little high, but the interesting thing was the barrel was rifled? The date code was KD. Did the first run of the usp have rifling my compact is date code KG and not rifled.
