Short answer: illegally Long answer: RA 10591. "ARTICLE II OWNERSHIP AND POSSESSION OF FIREARMS SEC. 4. *Standards and Requisites for Issuance of and Obtaining a License to Own and Possess Firearms.*– In order to qualify and acquire a license to own and possess a firearm or firearms and ammunition, the applicant must be a Filipino citizen, at least twenty-one (21) years old and has gainful work, occupation or business or has filed an Income Tax Return (ITR) for the preceding year as proof of income, profession, business or occupation." And to transport: "SEC. 18.*Firearms for Use in Sports and Competitions.*–*A*qualified individual shall apply for a permit to transport his/her registered firearm/s from his/her residence to the firing range/s and competition sites as may be warranted." Since a foreigner is not a "qualified individual", as stated above nor permitted to register a gun it is COMPLETELY illegal to own, transport, sell or possess a firearm. Possession (which can be just simply holding a gun) is illegal for a foreigner. It's a bit tricky to shoot a firearm without first possessing it. It IS illegal and if someone that doesn't like you sees you doing so said person CAN have you arrested. I don't care what anyone else says....the law is VERY clear. Getting away with breaking the law is a different story though.
