I just ask because I just realized today that I have one German (AK) HK45c and one American (AI) HK45c. At the range they both performed as world class, navy seals, kick ass pistols, and to be honest I love the idea of owning a American made pistol (that isn't a knock against German stuff). The only difference I've noticed it the American one has a "P" with a liberty bell symbol and the German one has the antler markings. Also the HK barrell from the US one has markings on both sides... Anyway are any of you weary of buying American made HK's? We see the difference between American Sig's and the old west German Sig's.
