That is more about the differences between guns than the actual round.RottenApple wrote:The muzzle of almost every 9mm I've ever fired tends to "flip", making it more difficult to require the target for the next round. It's just too....."snappish". .45 ACP, OTOH, just pushes back into my hand. Especially with the 1911s. My sights stay on target through subsequent shots. All in all, it's just a more comfortable round for me. I'm far more accurate with a 1911 in .45 than I am with any other handgun.
Shoot a 9mm in an all-steel 1911 and you won't feel much muzzle rise or snap.
