Is 35.F.R.S.C. 2.4(f) of the Federal Criminal Code a constitutional right to carry a concealed weapon?

Defendant claims 35 C.F.R. 2.4(f) violates the Second Amendment of the United States Constitution. That regulation makes it a misdemeanor to carry in violation of state law. California Penal Code section 25400(a) (formerly, section 12025(a)(1)) prohibits the carrying of a concealed weapon in the manner described therein. Defendant argues that the statute violates the rights guaranteed under the Second Amendment of the Constitution of the United States as interpreted by District of Columbia v. Heller, 544 U.S. 570, 595 (2008).
