Regarding self-defense, 9mm & 10mm both are the best caliber options. Before knowing the differences, it's essential to see the overview of both calibers, especially for new gun owners.
9mm ammo is known as the king of handgun calibers in the world. It's a widely used caliber by many handguns and some submachine guns.
Popularly known as 9mm Luger & 9mm NATO. As these are popular names of 9mm, still there are slight difference between Luger vs NATO 9mm calibers.
It was first developed by German arms manufacturer Deutsche Waffen-und Munitionsfabriken (DWM) in 1902. It is 9mm in diameter and 19mm in length, a rimless, bottlenecked cartridge.
The higher magazine capacity, less recoil, affordability & ease of finding options make it a good choice for self-defense, law enforcement, and military applications.
The 9mm cartridge is relatively small and compact, making it easy to carry, and it typically has low recoil and good accuracy.
Several types of 9mm ammunition are available, including a full metal jacket (FMJ), jacketed hollow point (JHP), and frangible. Each type of ammunition has specific characteristics and is used for different purposes, such as target shooting, self-defense, and training.
Some common 9mm firearms include the Glock 19, Sig Sauer P229, and Beretta 92.
The 10mm is a semi-automatic pistol cartridge introduced in the 1980s. The caliber is known for its high velocity and stopping power. That makes it a popular choice for hunting and self-defense.
The cartridge case capacity of 1.56 milliliters (24.1 grains H2O) can be a good option for competition, recreational shooting, home defense, and hunting medium to large games.
The 10mm is slightly larger, which makes it difficult to control over the 9mm luger. The higher muzzle energy and velocity of the 10mm Auto make it more powerful than the 9mm Luger. Because of its effective stopping power, it's a good option for hunting and wilderness protection.
10mm Auto is available in various bullet types like FMJ, Hollow Points, Soft Point & more. Available to buy from 60 to 205-grain bullet weights.
Some common 10mm firearms include the Glock 20, Smith & Wesson 1006, and the Colt Delta Elite.
Before moving to the comparison section, it's essential to understand that choosing a caliber will depend on a person's requirements or preferences. People have different choices on caliber weight, size, power, recoil & use.
After the overview, let's compare the 9mm & 10mm calibers by their development, applications, accuracy, stopping power, recoil, magazine capacity, price & availability.
In 1902, the 9mm ammo or 9mm luger was developed by Georg Luger. The cartridge was designed initially with military handguns but has since become famous for self-defense and target shooting.
This new caliber improved on the previous handgun ammunition, which was large and heavy. Still today, the compact cartridge has less recoil and allows for easy handling.
The 10mm Auto cartridge was developed by Jeff Cooper in 1983 and was first introduced by the Bren Ten pistol. It was designed to provide a high-power, high-velocity round for law enforcement and personal defense applications. The cartridge initially gained popularity but fell out of favor in the 1990s due to issues with firearms designed to handle the cartridge's high recoil.
However, the 10mm has since regained popularity and is now widely used for hunting, self-defense, and competitive shooting. It is a versatile cartridge that performs well in various shooting scenarios.
Bullet size is significant for the best shooting experience. A larger & heavier bullet will deliver more damage to the target.
9mm comes with an approximate bullet weight of 108gr to 147gr & overall length of 29.69 mm (1.169 in). A 9mm cartridge uses a bullet usually between 9mm and 10mm in diameter.
Other hands 10mm have 60 to 205-grain bullet weights & overall length of 1.26. The 10mm cartridge uses a bullet, usually between 10mm and 11mm in diameter.
When we compare the 9mm and 10mm in size or weight, the 9mm is smaller, more compact, and has less power. 10mm is comparably larger, heavier, and more expansive. Therefore, it can hold more gunpowder and stopping power.
Stopping power is the most significant decision point when comparing 10mm vs. 9mm.
While we compare the 9mm & 10mm, the 10mm is considered to have a higher stopping power than the 9mm. It comes with 55 percent greater average muzzle energy than the 9mm.
10mm will offer you a higher upper limit in energy and velocity.
In ballistics gel tests, a 9mm would typically travel about 13 inches after impact, while the 10mm was sometimes over 17 inches. This means that a 10mm could travel through two people at center mass and keep going. That is a vast amount of power.
Recoil is one of the more significant reasons why people prefer 9mm or 40 S&W over 10mm.
9mm less recoil is helpful to improve accuracy and is easier to handle, allowing for better shot placement. An average 9mm will have about 4.5 ft-lbs of recoil energy in a standard loading, while a 10mm will have almost triple that at 12.85 ft-lbs of energy.
Essentially, the 9mm is much easier to shoot rapidly, which is a key factor for self-defense and competition.

|PMC 9mm 115gr JHP
|Sellier & Bellot 9mm 124gr FMJ
|Speer Gold Dot 9mm 147gr JHP
|PMC 10mm 170gr JHP
|Sellier & Bellot 10mm 180gr FMJ
|Speer Gold Dot 10mm 200gr JHP
As per the magazine capacity comparison, 9mm has a higher capacity than 10mm. Most 9mm handguns have a magazine capacity of 12 to 15 rounds*. It's not final; it depends on the various gun types you are using.
On the other hand, 10mm has a smaller magazine capacity than 9mm because of its size. This will be different for different 10mm handguns.
Let's take an example. A standard Glock 17 magazine can carry 17+1 rounds of 9mm. On the other hand, the Glock 20 magazine can hold 15+1 rounds of 10mm Auto.
So, the 9mm is the winner in terms of magazine capacity.
Muzzle velocity refers to the speed at which the bullet travels once exiting the muzzle. The heavier the bullet, the higher its velocity and energy.
Comparing both calibers per muzzle velocity, 10mm have a higher muzzle velocity than the 9mm rounds. The 9mm has a muzzle velocity of around 1,200*fps (360 m/s), while the 10mm caliber comes with a higher muzzle velocity of up to 1,400* fps (430 m/s).
So 10mm is a faster caliber capable of delivering more energy to targets.
It is important for the bullet to have deep penetration upon entering the target, for the best and most devastating results.
The 9mm has a significant advantage over the 10mm when it comes to penetration. The 9mm bullet is designed to penetrate deep into the target and does so quite effectively.
On the other side, the 10mm bullet is designed to expand faster and doesn't penetrate as deeply as the 9mm.
When choosing handguns for 9mm & 10mm, there are many options available in every gun store.
There are many more options for handguns chambered in 9mm than in 10mm.
As per the power comparison, a 10mm handgun is more powerful than a 9mm handgun.
On average, a 9mm handgun can create 350 ft/lbs.* of energy. On the other hand, 10mm firearms can generate an average of 530 ft/lbs.* of power.
Many good 9mm handguns are available in the market, including Glock 19, Glock 17, and Glock 43.
The best 10mm handguns are 1911 10mm, Glock 20, Glock 40 & more.
When we compare 9mm & 10mm by price & availability, 9mm will be the winner.
As per the availability, both calibers are readily available to buy at every ammo store in the USA. Every seller lists these two handgun calibers at the top of the list.
For the price comparison, 9mm ammo is affordable because of its high demand compared to 10mm.
On the other hand, the bigger size of 10mm Auto requires more material to produce, so it's more expensive.
9mm ammo approximate Per Round Cost: 0.17 To $2.10(at the time of writing this post)
10mm approximate per round cost: $ 0.35 To $3.30 ((at the time of writing this post)
So, 9mm will be the winner for availability & price.
