Does the 10mm Glock have a .22 unit available for it? A 9mm slide group for it? The 1911 460 does. Actually, you can nearly always get away with using .45 ACP ammo in the .460 Barrel, actually. The extractor holds the casehead back against the breechface, tight enough to get reliable firing. A great many ignorant people "think" otherwise, but that doesn't make it so.
