I have some made in the USA by foreign owned companies, such as Sig and FN, at least one made abround for a US Company (BHP) and a number made abroad by foreign companies. Canada, Germany, Spain, Israel, Argentina, Switzerland, Slavic Republic, Italy, Russia and Bulgaria come to mind. Then there are the "all US" Colts, Kimber, Ruger, Springfield, Smith & Wesson, Marlin, DPM, Bushmaster, Rock River, Winchester and Browning offerings.
I may be in the 50% range, by your way of counting. 100% were bought from either a US businessman or an individual US citizen.
