9mm vs 45 ACP ammo: Which One is Better?

The 9mm vs 45 ACP ammo is an old-age debate among the military, law enforcement, and hunters. You will not miss this debate among gun forums. Both handguns have a huge following and popularity. This can be attributed to their success in the field.

Which is the better handgun between the 9mm and 45 ACP (Automatic Colt Pistol)? You need a flexible stance when deciding between these two handguns. The biggest mistake most people do is taking a black-and-white stance

The 45 ACP shoots bigger bullet calibers while the 9mm has a higher capacity. So, what makes a better handgun ammo?

Comparing 9mm vs. 45 ACP

Different shooters will be right in picking one handgun over the other and with valid reasons. What matters most to you when choosing a handgun? Having bigger bullets and having more capacity are great considerations. These two cartridges have a debate that is over 100 years. While each cartridge comes with its pros and cons, there is no definitive way to decide on the best.

For most people, the .45 ACP ammo is the better cartridge since it shoots bigger and heavier bullets. However, when deciding on a suitable one, it is important to disregard the hype and look at the facts. An unfired ACP 45 is only 0.095 inches bigger than the 9mm. You need to analyze and decide on the better cartridge based on different factors.

To start our comparison, let’s have a look at the two handguns under different factors


If penetration is your main consideration, then consider the 45 ACP.  The A 45 averages a penetration of 11.3 inches to 14.3 inches. The 9mm on the other hand averages 8 to 15.9 inches. However, this varies greatly depending on the specific handgun used. For example, the Remington FMJ on the 45 delivers up to 27 inches of penetration. When using a 9mm on the Winchester FJM, shooters can achieve penetration of up to 24.5 inches.

Penetration is a crucial consideration when hunting big game. It can ensure an immediate kill for such big bucks without wasting a shooting opportunity. Make sure you understand your target game and choose the right caliber.

Magazine capacity

Next, we can consider the magazine capacity. Under magazine capacity, the 9mm is the obvious winner due to the small size of the rounds. Most 9mm handguns have a higher rounds capacity than the ACP 45. However, specifics can vary depending on the exact type of gun. If you have small guns with small load capacities, then choosing a 9mm cartridge makes sense.

For example, the Glock 17 holds up to 17 rounds of the 9mm which is pretty good. However, the Glock 21 can only hold 13-standard ACP 45. While both guns perform well, the ideal caliber choice comes down to the main purpose. A higher load capacity might be needed when hunting feral hogs that require semi-automatic shooting, especially when in a group. The choice of the suitable caliber comes down to what best works for you.


While handguns are not known for huge recoils, you need to consider this when deciding between a 9mm and ACP 45. The 9mm ammo has less recoil than the ACP 45 because of the small round size. Shooters can enjoy faster and more rounds of shooting without having to deal with recoils. The small bullet size leads to small recoil making it a safer choice for first-timer users.

The recoil on the ACP 45 is much higher due to the bigger bullet size. The .45 ACP holds bullets that are 11.5mm bigger making the recoil higher. If you need to have more shots taken consecutively, then the ACP 45 is not the best option. You’re likely to suffer from recoil as opposed to using the 9mm.


Velocity is another crucial consideration to make when deciding between these two. The 9mm has a higher velocity of between 900 to 1350 feet per second. The ACP 45 velocity is relatively small ranging between 835 to 1150 feet per second. You need to understand your shooting range and see if velocity is a major factor to consider.

The bottom line

There is no better choice between the ACP 45 and 9mm cartridges. These are just two different cartridges with pros and cons. Both cartridges can serve you well in different situations. You just have to pick what best works in your situation and learn to use it.

The 9mm cartridge was designed in 1901 and developed in 1902. The ACP 45 was developed in 1904 and was widely used in World War 1. As you can see, both cartridges have been in use for over 100 years, and rightfully so. Decide on the features that best work for your shooting situation and pick one cartridge that best serves you.

Top 5 Best Long-Range Cartridges For Long Range Shooting

When planning on long-range shooting, you need special cartridges designs for long-range shooting. Long-range shooting is quite relative. The long-range varies greatly from 200 yards to as far as 2000 yards. These cartridges have a reasonably flat trajectory and downrange energy. They can travel far on a straight trajectory. They usually have enough power to gun down big game animals.

Choosing the best 5 long-range cartridges can be a challenging task as different disciplines have different demands. However, we can attempt and rank the top 5 cartridges for long-range shooting.

.300 Win Mag

The .300 Win Mag is considered by many the optimum long-range cartridge and rightfully so. This is a large-game cartridge that has proven itself worldwide. This cartridge with the right long range 300 Win Mag scope is also a top choice for long-range snipers with the capability to launch heavy bullets at high precision and speeds. However, it features a pretty stiff recoil that some find hard to master. Expert shooters can shoot beyond 1650 yards at supersonic speeds.

The .300 Win Mag comes with a ballistic coefficient of 0.615 500-yard velocities, 2346 fps 500-yard energy, and 2200ft/lbs 500-yard drop. It is a useful cartridge for cross-country long-range and 100 yards for slow fire matches. This cartridge is pretty versatile and a good choice for shooters that engage in different disciplines.

6.5 Creedmoor

The 6.5 Creedmoor long-range cartridge combine with the top rated 6.5 Creedmoor scopes is by far one of the best choices in the market over the years. The cartridge has had a huge effect on American long-range precision shooting since its introduction in 2007. Since the 30-06 cartridge which is another excellent long-range cartridge, no other cartridge has had such a huge impact on long-range shooters as the 6.5 Creedmoor.

The 6.5 Creedmoor has opened a new realm of possibilities for shooters. The cartridge features the highest ballistic-coefficient projectiles at high velocities. It also features a case and a chamber designed for inherent accuracy. The 6.5 Creedmoor provides a consistent connection to 1000 yard targets and beyond. It can reach a maximum range of 1400 yards.

This cartridge features an excellent barrel and a polite recoil making it easy to focus without worries of a recoil. It also comes with an aggressive muzzle brake allowing users to spot impacts downrange on still targets. Overall, the 6.5 Creedmoor is a direct ancestor of the 30TC and trounces the .308 Win.


The .308 is another capable long-range cartridge introduced in 1952. It is a pretty reliable cartridge that finesses the load and holds the tongue just right. With the right scope for 308, the cartridge can shoot to maximum ranges out of 1000 yards. This cartridge can achieve high precision with an arched trajectory that can make a rainbow appear flat. It features a .300 parent case and is a suitable choice for matches regulated to .308.

However, the .308 comes with a major weakness due to its lack of propellant capacity for pushing heavy-for caliber bullets at useful velocities. It compensates for its lack of propellant force by being heavy and streamlined with a stretched-out profile. There is a lot of good and bad when it comes to choosing the .308. It features an outstanding barrel life but a very annoying recoil.


This is by far one of the oldest long-range cartridges. It was developed as a military cartridge in 1906 during the buggy and horse era. For most people, the cartridge should be outdated, worn out, and even retired. However, this cartridge is still widely used and competes effectively with recent long-range cartridges like the .308 Winchester and .300 Ruger Compact Magnum. So, how does the 30/06 hold up against today’s prospects?

This cartridge has greatly changed since its inception as a military cartridge. It is now considered the best long-range hunting cartridge. The cartridge is long and tapered for smooth flow and extraction from and out of chambers. The bullet features a long robust neck to help resist case distortion. Over the years, the cartridge has changed with necks becoming shorter, shoulders steeper, and case walls more parallel. Nowadays, modern powders and bullets make the .30-06 a more effective cartridge making it an effective choice for long-range hunting.

.338 LAPUA

This is another versatile long-range cartridge favored by snipers and military across the world. The cartridge is considered the “death ray” of the Global War on Terror. It features the flattest trajectory with most observers calling it laser-like. This is a precise cartridge that was specifically developed for sniping. The development originated from the US Marine Corps for long-range sniping to penetrate bodies at 1000 yards.

The cartridge features a case that can handle high pressure and a 350-grain bullet which still remains the standard choice. Overall, this is a popular cartridge and one that has proved vital with special operation units. One of the biggest advantages of the .338 Lapua is its accuracy at long ranges. It comprises some of the best optics in the industry.
