The 9mm Luger has a muzzle velocity of 1,150 fps and energy of 335 ft-lbs, with significant drop at longer distances.

22 vs 9mm: Is it a Fair Comparison?

The 9mm and .22LR are both popular types of ammunition available on the market, known for their distinct cartridge sizes.

When comparing these two calibers, the size difference between them is quite evident, as the 9mm is larger than the .22 round.

When it comes to energy, the .22LR rounds possess noticeably less power in comparison to the 9mm rounds, mainly due to their smaller powder load. Overall, the .22LR exhibits lower acceleration and kinetic energy.

This difference in power results in variations in penetration and knockdown power, with the 9mm caliber surpassing the .22LR in these aspects.

However, it’s important to acknowledge that this doesn’t mean the .22LR lacks its own merits or usefulness in certain situations.

22 vs 9mm: Cartridge Comparison

The 22LR is one of the most prevalent rounds and is what many of us have used since childhood.

The bullet has a diameter of 0.2255 inches, while the base diameter measures 0.226 inches.

Within the overall length of a 22LR, which is approximately 1 inch, the case length accounts for 0.613 inches.

It is important to note that the maximum pressure according to SAAMI standards is 24,000 pounds per square inch (psi).

The 9mm bullet has a diameter of 0.355 inches, while the base diameter measures 0.391 inches.

In terms of the overall size of the round, the case length of the 9mm accounts for 0.754 inches out of a total length of 1.169 inches.

The maximum pressure allowed according to SAAMI standards for the 9mm is 35,000 pounds per square inch (psi), which is more than 10,000 psi higher than that of the 22LR.

22 vs 9mm: Ballistics

When it comes to shooting, we favor flat-shooting rounds because they necessitate less adjustment as the distance to the target grows.

Neither of these calibers was specifically designed for long-range shooting, thus both exhibit subpar trajectories.

At a distance of 100 yards, the 9mm bullet experiences a drop of over 12 inches.

The 9mm round was primarily designed for handguns, and therefore, taking a shot at 100 yards is not realistic.

The 22 LR, at a distance of 150 yards, experiences a drop of 11 inches.

Looking at the trajectory between the 22LR and 9mm, the 22LR is the clear winner. However, it is worth noting that the 22LR is typically fired from a rifle, which accounts for the flatter trajectory.

Which is Better for Hunting and Self Defense

Hunting

As I mentioned in the beginning, I grew up hunting rabbits, squirrels and skunks with a Ruger 10/22 chambered in 22LR.

When it comes to hunting, comparing the 9mm and .22LR is somewhat unfair since the 9mm was never designed specifically for hunting purposes. In this regard, the .22LR ammunition proves to be a superior choice for hunting.

Obviously, we are not talking about taking down big game, but rather focusing on small game.

While the 9mm can technically be used for hunting, it is important to note that it will more than likely obliterate the meat you’re attempting to harvest.

Although these calibers were not specifically designed for hunting big game, when it comes to small game hunting, the .22 holds a slight advantage.

Keep in mind though, In most states, it is illegal to hunt anything larger than a coyote with a 22 caliber firearm.

Self Defense and Concealed Carry

The general consensus among most gun owners is that the 9mm is a superior choice for concealed carry and home defense. This is primarily attributed to its increased stopping power.

However, with the proper shot placement, if all you have is a 22, it’s certainly better than nothing. It won’t do the damage of a 9mm, but it’s still gonna hurt like hell.

Will a .22 stop an attacker? Lucky Gunner conducted a test on a 1.9-inch snub nose revolver firing .22 rounds into ballistic gel. All five rounds penetrated the gel, achieving a depth ranging from 10 to 12 inches.

As expected, there was no expansion, which is typical for .22 caliber bullets.

The FBI establishes a minimum standard of 12 inches of penetration for duty ammunition, but achieving 10 inches is still a commendable feat.

Having said all that, the .22 caliber firearm lacks the necessary kinetic energy to effectively penetrate and incapacitate an attacker. It is widely known for its failure to penetrate the skull or reach vital organs by penetrating deep enough into the tissues.

Your most viable option would be to aim for soft tissue areas like the neck and face. These areas are highly prone to bleeding, which can cause a psychological deterrent. A sufficient amount of blood in the face, accompanied by the associated pain, might be sufficient to halt the attacker, although it cannot be guaranteed.

It is important to note that multiple shots will likely be required, considering the .22LR’s reputation for inconsistency and malfunctions.

22 vs 9mm: The Backstory of These Two

9mm

At the dawn of the previous century (1901), the 9mm was conceptualized by G. Luger, an Austrian firearm designer. It was initially developed as a service cartridge to accompany Luger’s semi-automatic pistol known as the Pistole Parabellum.

Following the conclusion of both World War I and World War II, the 9mm cartridge gained significant popularity among military and law enforcement agencies in Europe.

However, its prevalence in the United States didn’t become widespread until the 1980s when the US Army officially adopted the Beretta M9 Service Pistol.

The 9mm gained significant traction in the United States during the 1980s and 1990s with the introduction of the Glock 17 and Sig Sauer P226.

The rest is history.

22LR

First introduced in 1887 and created by the J. Stevens Arms & Tool Company, 22LR was specifically designed as an entry-level cartridge for young shooters, and it served that purpose for numerous decades.

Shortly after its debut, it gained popularity as the go-to choice for plinking, target shooting, and controlling varmints.

And although 22LR does not have proven applications in the military as the 9mm does, it does have some roots in the intelligence and covert action community.

The 22LR has a very interesting history with the Israeli Mossad in real-world clandestine operations.

Following the 1968 hijacking of an Israeli airliner, the government began a secret program to put armed sky marshals on its flights armed with Beretta Model 70 handguns chambered in 22LR.

In 1971, a Sabena Airlines jet was hijacked by members of the Black September terror group. Several Israeli operatives disguised themselves as aircraft mechanics (with concealed Beretta Model 70 handguns) to approach the plane and "fix a problem with the hydraulic system" killing two of the four hijackers.

They were used again during the famed Operation Wrath of God in 1972.

These compact and concealable 22LR pistols played a leading role in Israeli covert action for many years to follow.

When it comes to ammunition for your Bobcat pistol, I highly recommend CCI ammo. You have the option of Stingers, Velocitors, or Mini Mags—depending on your preference. Personally, I find the Velocitors to be preferable as they utilize a heavier bullet, resulting in improved penetration.

Recommended 22LR Ammo for Self Defense

If you choose to carry a .22 LR for self-defense, it is important to familiarize yourself with ammunition specifics and test that ammo in your carry gun.

Many of the conventional rules regarding ammunition don’t apply in this case. Previously, a jacketed hollow point was preferred, but the situation changes when using 22LR ammo.

While a hollow point .22 LR is effective for hunting, its expansion slows the round’s velocity enough to impede sufficient penetration. When it comes to defensive purposes, expansion is a characteristic we don’t necessarily want with .22 LR ammunition.

In the case of .22 LR, the focus should be on penetration. Even small entry wounds can cause significant damage if they are accurately placed in critical areas. It’s all about shot placement with the 22LR round.

Fortunately, a few 22LR rounds have demonstrated reliable performance and meet the minimum standards set by the FBI.

Federal Punch

The Federal Punch personal defense round is another excellent option. It is a relatively new round specifically engineered for self-defense purposes.

This round demonstrates consistent penetration capabilities and features a nickel-plated construction.

The Nickel plating provides a protective layer to prevent corrosion, especially from the effects of sweat. Since these smaller pocket guns are commonly carried in deep concealment positions, they tend to be exposed to higher levels of perspiration.

CCI Velocitor

Although the CCI Velocitor was not specifically designed to excel when fired from a short barrel, the semi-hollow point round weighing in at 40 grains boasts a reported velocity of 1,435 feet per second.

In direct comparison to Federal Punch, though, CCI Velocitors exhibit lower velocities, averaging around 200 feet per second slower. That alone gives the Federal Punch a distinct advantage in penetration.

Both of these rounds perform flawlessly out of my KelTec P17, so that’s why I chose them. Let us know in the comments if you’ve had a different experience with these rounds -OR- let us know what you use.

Wrapping it Up!

We have discussed the key factors to consider when comparing .22 LR and 9mm.

Several advantages favor the use of .22 LR: it offers lighter recoil, tends to be more accurate, and is cost-effective for training purposes.

However, 9mm pistols can be concealed just as easily as .22 LR handguns and their stopping power is by far superior.

It’s also advisable to familiarize yourself with the fundamentals of human anatomy, particularly regarding target areas. Personally, I prefer carrying a slightly larger caliber, such as a 9mm.

I haven’t had enough experience with my .22 pistols to have full confidence in relying on them to protect my life… at least not yet.

Although we give the upper hand to the 9mm, it does not mean that .22 LR has nothing to offer.

By selecting a reliable pistol, high-quality ammunition, and dedicating time to practice, you’ll be able to mitigate many of the issues inherent with 22LR.
