What Is 45 Of 40 – When choosing a pistol cartridge for your handgun or home defense, you can’t go wrong with a 40 Smith & Wesson (S&W) or 45 ACP.
Both cartridges have served shooters faithfully for decades. 45 ACP made its mark in the trenches of World War I and served the US Army faithfully throughout the Vietnam War. 40 S&W, on the other hand, has outperformed LEO, FBI, and CCW license holders in the concrete jungle from the 1990s to today.
What Is 45 Of 40
However, many shooters find themselves in a dilemma when deciding to buy a new semi-automatic pistol: which one is better? 40 S&W or 45 ACP?
In this article, we’ll review every pistol cartridge and analyze all the ballistic data so you don’t have to! By doing this, when you walk into your favorite local gun store and pick out a new self defense pistol, you will know which one is best for your needs.
45 ACP (Automatic Colt Pistol) is a frameless, centerfire, straight bore pistol developed by John Moses Browning in 1904. After success in military trials, it became the standard pistol for the Colt M1911 pistol. 45 ACP is capable of firing a 230-grain bullet at 830 feet per second (FPS) with an Army-standard muzzle energy of 356 foot-pounds.
40 S&W is a rimless centerfire pistol cartridge developed by Smith & Wesson and Winchester in the 1990s to meet the FBI’s need for a more effective defensive bullet. The FBI initially adopted Lt. Col. Jeff Cooper’s 10mm automatic pistol as its new service round, but soon found that the recoil was too much for the agents to handle. The basis of the 40 S&W is the development of a reduced power load. The standard .40 S&W fires a 165-grain bullet at 1130 FPS with a muzzle energy of 468 foot-pounds.
Both of these cartridges are great for concealed carry and with the right jacket hollow point (JHP) you have no problem stopping the bad guys in a self defense situation.

But are 40 and 45 the right choice for you? Or should you choose a 9mm Luger, 357 Magnum, 10mm Automatic or 357 SIG?
In the following sections, we will analyze the pros and cons of the 40 S&W and 45 ACP to help you answer that question.
Since the advent of concealable and reliable semi-automatic pistols, firearms experts have debated which caliber has the greatest “stopping power.” You’ll hear things like, “The 357 Magnum is the real terminator!” or “I only carry the 45 ACP because it’s too powerful!” Insert your favorite cartridge in the previous sentence To keep the pistol caliber debate going.
The concept of stopping power has never been quantified and is generally thought of as the ability of a bullet wheel to stop in a self-defense situation.

A shot’s ability to weaken an opponent’s will to fight is very subjective. Since life isn’t a D&D game, we can’t go to the local witch and use a modifier on our pistol to drain constitution (roll 2d20 for crit).
If we believe that hitting the attacker hard enough will force them to surrender, we can compare the muzzle energy of the 40 S&W and the 45 ACP.
Looking at the ballistic chart below, there is no significant difference in kinetic energy between the 40 and 45. There are certain ammo that perform better in certain ways, mainly the +P variety, but generally speaking, the muzzle energy of these two pistol rounds is about 400 foot pounds of force.
The 40 S&W typically shoots lighter bullets at a higher velocity, while the 45 ACP shoots heavier bullets at a slower FPS.

So if the impulse between rounds is muzzle energy, then it depends on the ability to deal damage to the attacker.
The simple fact is that the 45 ACP fires a wider diameter bullet than the 40 S&W (.452 inch vs. .40 inch). The winding channels created by the casing hollow points are superior to full metal casings (FMJ). This is because JHP expands when it touches soft tissue, while FMJ does not. You should always carry a quality JHP in your personal defense pistol.
As the hollow point expands, you should expect its diameter to increase by 90-100%. This means that under ideal conditions your 40 S&W will open to 0.80” and your 45 ACP will open to 0.90”. It’s not a big difference, but it’s different.
Sometimes a tenth of an inch can mean the difference between hitting a major organ and causing only peripheral damage.

Recoil is important when considering a pistol cartridge for your sidearm because it affects subsequent shots. The more recoil and muzzle spin you feel, the longer it will take to re-focus the sights on the target when you fire again.
Every shooter wants a pistol with the recoil of a 9mm Luger and the power of a 357 Magnum. Unfortunately, you can’t have your cake and eat it too when it comes to recoil.
You would normally expect more recoil from a bullet that fires a heavier bullet, but that is not the case with the 40 vs 45.
Many shooters report that the 45 ACP has less recoil than the 40 S&W. This is because 45 ACP rounds are typically fired at subsonic velocities (less than 900 FPS) and have a lower total chamber pressure than 40 rounds. This has led many fans of the 45 ACP cartridge to describe the recoil as thrust.

Since the 40 S&W is only a 10mm Auto lite rifle, the chamber pressure of the 40 is much higher and it fires a 165 or 180 grain bullet at a much higher velocity than the 45. This combination created what many shooters described as incredibly nimble and sharp recoil similar to the 357 SIG.
Recoil is very important to consider if you plan to carry a lightweight subcompact pistol concealed. Smaller guns absorb less recoil, so more energy can be transferred to the shooter’s wrist. For example, a shooter will experience less recoil when shooting a full-sized Glock 21 or Colt 1911 than a smaller Glock 30, Springfield XD-S, or Beretta Nano.
Thanks to the lower charging pressure of the 45 ACP, it has the advantages of less recoil and faster follow-up fire.
After the 1986 Miami shootout, the FBI conducted extensive ballistics gel testing to evaluate defensive handgun projectiles. They found that for a self-defense cartridge to be considered effective, it should have a reliable extension capability with 12-18 inches of penetration.

When it comes to penetration, you want to shoot the heaviest bullets at the highest FPS you can handle. A heavier bullet moving at a higher speed will carry more kinetic energy and allow it to penetrate deeper.
As for the 40 S&W and 45 ACP, the difference in penetration between the JHP is not that great. However, since the 40 has a higher FPS than the 45, it will generally penetrate a bit deeper.
When the hollow point expands, it prevents excessive penetration and deals additional damage to bad guys. Therefore, you should never carry an FMJ in a self-defense handgun, as FMJs do not expand and can leave bad guys behind, potentially injuring innocent bystanders or damaging private property.
Premium sheathed hollow points such as the Winchester PDX-1, Federal HST or Spell Gold points have been proven by North American law enforcement agencies to provide superior penetration and terminal ballistics.
Best Defensive Ammo: 9mm Vs. .40 S&w Vs. .45 Acp
One last thing to consider is that self defense is usually a bit hotter than FMJ practice. This is so that the hollow point has enough FPS to penetrate deep enough to stop bad guys.
Companies often lighten the practice load because it saves money and also provides a more enjoyable shooting experience for the end user.
Therefore, you should fire at least 1 magazine of defensive rounds from your sidearm every time you enter the range. This way, you get used to the recoil and FPS increase you’ll experience when shooting at full power with a hollowpoint jacket.
If you need excellent penetration and muzzle velocity, the 40 S&W is the right choice for you.

Accuracy is a difficult category to quantify because it is highly dependent on the skill level of the shooter and the shooting platform they are using.
Most shooters will report being more accurate with bullets that feel less recoil. This suggests that the 45 ACP would be a better choice for accuracy. However, several LEOs I know are literally 40 year old surgeons.
Higher recoil pistol bullets can sometimes cause the shooter to flinch, either because they are surprised by the pistol firing or in anticipation of the recoil. flinching throws the bullet off target because the shooter interferes in the sight in front of the bullet
