The difference in effectiveness between the 9mm and the .45 is fairly small with modern bullets, and nigh-nonexistent between 9mm / .40 and .40 / .45. Ditch that silly prohibition on expanding ammunition, stick with the 9mm, and use a quality hollowpoint.
And congrats for correctly citing the Hague convention, instead of the often-mis-cited Geneva convention :)
