Overall, the 45 ACP is a bigger, fatter, slower round than the 9mm resulting in shallower penetration for the venerable. Advancements in hollow point technology have brought the 9mm bullet on par with the 45 ACP but the.
The double-stack design allows for more magazine capacity at the cost of the magazine being wider. We have double stack mags, too!
Your standard Glock 17 magazine holds 17 rounds of 9mm ammo, while the Glock 21 magazine can only hold 13 rounds of 45 ACP. Being able to bring more ammo to bear in a self-defense situation allows you to stay in the fight longer before you have to result to hand-to-hand combat.
This gives the 9mm a distinct advantage as any shooter will always pick more bullets over less. The military seems to agree with this concept based on their decision to switch from the Winchester to the 5.
However, please be aware of your state laws as some states like New York and California restrict high-capacity magazines. In this case, those higher capacity magazines might not be a true advantage so always be aware of what you are allowed to carry.
However, all things being 2A Equal, the 9mm allows a responsible concealed carry permit holder or police officer to carry more ammo into a gunfight and that is a distinct advantage over the 45 ACP. The 9mm Luger has approximately half the felt recoil of the 45 ACP, and this is the third major point of debate in the 9mm vs 45 ACP battle. The 9mm cartridge fires a lighter bullet at a higher velocity, whereas the 45 ACP fires a heavier bullet at slower velocities.
This means that the heavier powder charge and heavier bullet in the 45 ACP is going to push back on the shooter harder than a 9mm. However, in general, 9mm handguns will have less recoil and allow for faster follow-up shots as shooters can get their sights back on target quicker. Less recoil also tends to lead to improved accuracy and shot placement.
Many shooters will find that they are more accurate shooting a 9mm and this is often due to less recoil. The gentler shooting 9mm allows shooters to focus on the fundamentals of shooting trigger control, sight alignment, grip, stance and develop good habits over bad ones like recoil anticipation.
Their findings suggested that less recoil allowed their agents to reduce their split times time between shots which allowed them to end engagements quicker with better shot placement. Lower felt recoil is an advantage for the 9mm Luger as it makes the firearm easier to handle, allowing for better shooting fundamentals and follow-up shots.
All things being equal, there is no difference in accuracy between the 9mm and 45 ACP. However, there is one caveat and that would be muzzle velocity. As the 9mm round fires a lighter bullet at a higher velocity, it will have less bullet drop over distance making it the better choice for long range shots. Although the 45 ACP will not be the best choice for long-range engagements, its lower muzzle velocity makes it is an ideal candidate for suppressed fire.
Being naturally subsonic and having lower chamber pressure, the 45 ACP is easier to suppress than a 9mm. With advancements in hollow point technology, the gap between the stopping power between the 45 ACP and 9mm has been closed to an extent. However, the fact that the 45 ACP has lower penetration makes it an ideal choice for home defense. Always know what your backstop is and what lies behind your target, as you are liable for every bullet you fire, even in a self-defense situation.
Regardless, 9mm recoil power stays in the four to five-pound range, making for a shot with easy handling and precise accuracy. Because a 9mm bullet is so much smaller than a 45, it makes sense that, when leaving the chamber, it pushes back on you with less force.
In terms of accuracy, a 9mm is the way to go, especially for amateur shooters. If you try to unload an entire clip too quickly, the low recoil energy really does not help all that much. Just because a 9mm has less recoil than a 45 does not mean it deserves any less professionalism and responsibility. You must make sure to follow proper gun safety rules when using any firearm. You know that recoil energy affects accuracy, but once you have gotten that part down, why is knowing the recoil of your gun important?
Well, the recoil energy from a gun can cause several safety issues if you are not aware of it. If you have never used a handgun before, you might be surprised at the power that can push back towards you when firing a round, regardless if it is a 45 or 9mm.
Although handguns are smaller than many other guns, they are still dense machines that require a lot of force. The larger the bullet and the gun, the more recoil you are going to have. So, if you have shot a 9mm before but have never handled a 45, do not expect the experience to be the same.
Several characteristics define the ballistics of different caliber bullets: the diameter of the bullet itself, what the bullet does on impact, grain amount, gunpowder level, and more.
While some of these aspects are not entirely relevant when debating 45 and 9mm, some might heavily influence your choice. It is important to note that some ballistic characteristics of the same bullet vary completely, so the below information may not always be what you come across. In any case, it is good to have a general idea of the ballistics of both a 45 and 9mm.
Since there is a separate section for 45 vs. It is also essential to keep in mind that when discussing the physical ballistic characteristics of a bullet, this involves both shooting things like gel targets and the act of self-defense. You might find different results in every article you read.
Many expert shooters have their own opinions on whether the stopping power of a 45 or 9mm is better. In the most basic description, a 45 bullet is wider. However, a 45 does not have as much velocity as a 9mm, so it may not penetrate as deeply, and therefore will not have as much stopping power.
Another notable ballistic characteristic is the foot-pounds ft-lb of muzzle energy. The larger ft-lb a bullet has, the more powerful it will be. A 45 bullet typically has ft-lb of muzzle energy. For a handgun, this is an insane amount of power.
As you may already know, the larger bullet requires a more powerful burning of gunpowder to send it out of the barrel. So, while it has more gunpowder than a 9mm, the larger size of a 45 cancels that out somewhat. Where The Great Debate between a 45 and a 9mm gets extremely heated is discussing the stopping power of a 9mm.
As you know from above, a 45 is wider, which may make it seem like it would have more stopping power. However, this is not always the case. Since a 9mm is smaller and lighter than a 45, it moves more quickly than a So, upon impact, the 9mm will penetrate the target much deeper than a It is shot out of the barrel at a much higher velocity, so it takes more stopping power to halt the bullet.
A 9mm also has a greater capacity. Because of their smaller size, you can hold more 9mm bullets in your magazine than you can 45 bullets. Some people, however, prefer larger bullets to more bullets, so it is really up to you to decide which characteristic is better. It seems that when you take one advantage, you give up another. In the debate between bigger bullets vs. Hypothetically, consider the case of self-defense from a home intruder. You may believe that one bullet or the other has better stopping power, so you will go with that gun.
However, some people opt for a 45 because it may lessen the risk of your bullet going through extra walls and causing damage inside or outside of your house since it is larger. On the other hand, the speed of a 9mm might make people practicing self-defense more comfortable when protecting themselves from an intruder.
Although there are distinct ballistic features between a 45 and a 9mm, you must also consider what specific type of bullet you have. There are two main models of a bullet: full metal jacket FMJ and hollow point. An FMJ bullet is made of a lead core with a metal shell. These dense bullets are excellent for target practice because they have great penetration capacity and are less likely to become deformed and mushroom on impact.
A hollow point, on the other hand, provides many different results. Hollow points — as you might have guessed — have hollowed out tips and centers. If you are shooting at something solid, you might consider FMJ bullets. Hollow-point bullets are better for soft targets. If you have a suppressor on your gun, your bullet will sound and act differently as it leaves the chamber. Reason: Current 9mm ammunition has more consistent and better barrier penetration than.
You can carry a lot more 9 mm rounds in the mag, and it is easier to shoot well. Both have only five rounds of ball ammo. Which one would you pick? I carry a. Reason: In the context of concealed carry for personal protection, my priorities are speed and accuracy, lethality and magazine capacity, so I go with the 9 mm without hesitancy. Speed and accuracy are both related to follow-up shots, which are generally more manageable in 9 mm. Reason: More so than any other pistol caliber, the 9mm has been the largest benefactor of handgun bullet design and technology and is a proven performer in the real world.
Although the recoil and performance of the. And bigger holes bleed faster. Reason: All of my pistols are 9 mm. Army Special Forces Soldier. I carry Hornady grain Critical Duty in mine and have seen it outperform. Reason: 9mm wins my vote on this one. Share this comparison:. If you read this far, you should follow us:.
