45 auto and 9 mm velocities are almost the same. The 9 mm cup pressures are generally higher than the 45 auto, almost twice. The bugaboo is recoil energy, almost twice as high in the 45 auto because of the bullet weight. Look at the mass that is recoiling in a Browning style 45 auto, the barrel and the massive slide and breech block. In the Luger you have the barrel and toggle only, and the toggle relies on clobbering the frame to break open.
