I know the LTW smiths could make a toaster fire flechettes, my VCR always tell the correct time and maybe even make a quality pepper grinder that is "actually" adjustable for different grinds (hint

), but from an absolutely fundamental mechanical point of view (and knowing that 1911 and 9mm aren't traditionally considered the best combo) would a full size, commander size or compact size 1911 in 9mm be inherently more reliable or practical from a purely engineering standpoint? I just figured maybe smaller 1911s in 9mm might be inherently more reliable than the fulls size. Any experiences or engineering perspectives?
