    45 acp has more stopping power than 9mm, however, 357 sig and 357 magnum have better stopping power than 45 acp.

    The .45 ACP is generally consider the gold standard in semi- automatic pistol stopping power, with the new modern expanding hollow points the 9 mm is only slightly less effective. No handgun is a death ray shot placement is the determining factor, hits in the thoracic triangle with any major caliber have a tendency to stop aggressors immediately. The major advantage of the .45 ACP is that it makes bigger holes giving it a greater probability of damaging vital organs.

    .45 ACP has more energy behind it so it will hit harder. 9mm is a nice round though, and definitely has adequate stopping power, especially in hollow points. 9mm is also easier to aim on quick followup shots and usually a higher capacity too.

    In the end, if you have 1 round in your gun and you HAVE to stop the target, you would probably want that one round to be .45 ACP. Both have their advantages and disadvantages though.

    I unfortunately have shot people with my .45 and an Army Beretta 9mm. I believe the .45 worked better. It's all about shot placement. If you're a good enough shot, either one will do. Use quality Hollow Point ammo. Don't skimp on cheap bullets. Horndady XTP works great for me. Federal Hydrashoks are great too.

    Thet both are good. If you can shoot it well the .45 is the way to go.

    If you are at all recoil shy the 9mm is fine.

    The .45ACP was designed to pick a large man off his feet, and knock him backward. This was to prevent the enemy from falling face first into a trench with his bayonet.

    The 9mm was designed to minimize recoil for the user, so smaller less experienced people could shoot more accurately

    You decide, a round designed to knock a 300lb bayonet wielding islander backwards, or a round designed to be less punishing for the user.

    The 9mm is the same diameter as a .380, a .38, and a .357, approx. The .45ACP was designed to replace the .38.

    The .45 is much larger, but slower. If you are hunting with a camp rifle @ 50+ yd, the 9mm would be better. Otherwise.......
