It's impossible right now because U.S. military surplus firearms need a retransfer authorization from the U.S. Department of State before BATFE Imports Branch will approve the import permit. The retransfers were banned by executive order in September 2013. Lets hope that this executive order will be rescinded by the incoming administration. I can't see how an import from the Philippines is any different or difficult than one from anywhere else. Many of the lesser expensive 1911/1911A1 clones plus other firearms and parts are regularly imported from the Philippines.
