The debate over the 9mm and .45 ACP is one of the most talked about in the firearms community. Both handguns/calibers have a huge following thanks to their popularity and success in the field. So which one is better you ask?
9mm vs .45 ACP Match Ups One of the biggest mistake that most people make is taking a black-and-white stance (only looking at ballistics stats) on the .45 ACP and 9mm.
Many will say that the .45 is better because it shoots a bigger caliber bullet, or that the 9mm is better because of its higher magazine capacity.
Both points are spot on and provide good reasons to prefer one over the other. Even if you think more bullets is better, you have to admit having bigger bullets with more bullets on tap are both worthy considerations when choosing one gun over the other. If you look at the bigger picture is that neither gun has a total advantage over the other one, and your own preferences will play a lot in determining which handgun is for you. Let’s take a look at the major points of each caliber to help you decide.
The 9mm Manufactured will pitch it as being compact and easier to handle than its .45 ACP counterpart which may be the many reason why the 9mm has become one of the most popular rounds in the gun world. Just like the .45ACP, the 9mm have served the U.S. military gloriously for more than 30 years. Yes, even the FBI dropped their .40 S&W pistol in favor of the 9mm. Here are some of the advantages that the 9mm has over the .45 ACP:
9mm Luger outperforms most of the premium line .40 S&W and .45 Auto projectiles tested by the FBI
9mm Luger offers higher magazine capacities, less recoil, lower cost (both in ammunition and wear on the weapons) and higher functional reliability rates (in FBI weapons)
The majority of FBI shooters are both FASTER in shot strings fired and more ACCURATE with shooting a 9mm Luger vs shooting a .40 S&W (similar sized weapons)
A question to consider for the pro .45ACP carrier, is carrying bigger necessarily better? The 9mm also has a higher muzzle velocity than the .45 ACP because it uses lighter bullets. Which has caused further debates within the firearms groups over which is better, a fast/light cartridge or a heavy/slow one?
The .45 ACP If you like the idea of shooting a gun with a lot of stopping power – you’re not alone. With its heritage engraved in history the trusted Colt M1911 to the modern .45 Glocks, it has always been a most reliable caliber for the gun owners. Many of us handgun lovers believe that bigger is better and love everything that the .45 ACP has to offer. Here are some of .45ACP’s best features:
.45s stopping power makes it a great home defense gun
Over-penetration isn’t as much of a problem
Battle tested for over 100 years which have produced some very powerful .45 ACP bullets
On a irrelevant side note, the .45 ACP is a very cool handgun.

But, that the 9mm capability caught up to the .45 ACP. What the experts are saying is that the modern 9mm is just as powerful. Take a look at these pics highlighting rounds that opens up to create possible nasty wound channels that can stop an attacker:
That is some serious expansion from the 9mm rounds. But don’t forget developments for the .45 is also available with FMJ.
While the 147gr Federal HST expanded from 9mm (roughly .35cal) to an average 15mm or .61″, the .45 ACP expanded from (again, roughly) 11.5mm to 25mm (.45″ to 1″) They both doubled in size…and since .45 ACP is bigger to start with, it became humongous in the end.
Not Breaking the Bank Affordablity, is something that the 9mm is in favor for the average shooters. Boxes of 9mm Luger are cheaper than the .45s ammo. When you’re spending some long range time, the 9mm isn’t going to break the bank.
Velocity – Suppressed We have to mention this because there are folks that love shooting their .45s suppressed. The .45 is a subsonic bullet, because it fires slow and its a heavy bullet, the muzzle velocity is lower than the 9mm which makes it damn near-whisper level.
Tactical Situation This is mainly for military and LEO’s but you could be faced with similar situation, if needed. Most of these folks have gone with the 9mm because they wanted the deeper bullet penetration. For home defense only, go with the .45 ACP for less penetration, you won’t have to worry about hitting innocent bystanders.
Last Shot What you choose to go with depends on your budget and life style. Each caliber has it good points, sometimes it depends on the owner. Are you a good shooter that can work that gun well? Or, are you just one that only wants to have a gun and never think of practicing with it. Maybe you’re the tactile person thats into the feel of a handgun. Some like the heavier weight with a decent kick. While others prefer the lighter recoil for rapid shots. Will you be carrying for open or concealed? For CCW, most will go with the 9mm because of the smaller profile. Again, its up to you. The good news is that which ever you choose, manufacturers has them for you to choose from. You’ll find the 9mm and .45 ACP for home defense, EDC, SHTF or just plinking papers. Which caliber do you prefer?, Let us know below.
