The .32 ACP is not the biggest cartridge you can buy, but it’s a very capable round in modern shooting.

.32 ACP Ammo | What Shooters Need to Know
A Classic Ammunition
The world of shooting is so dynamic and large. You can spend a couple of years doing these modern shooter articles breaking down everyone’s favorite types of ammo.
Even then, you can only come close to finishing. This time around, I’m going to tackle the .32 ACP — a handgun round that has been around since 1899.
Always more popular in Europe, .32 ACP pistols Automatic Colt (.32 ACP, .32 auto, 7.65 Browning, 7.65X17mm, etc.) is usually found in highly concealable pocket firearms. While the 32 ACP ammo ballistics are less than ideal, it does hold a place in a self-defense shooting.
Oftentimes, these small guns make great backups. That’s because they’re so tiny they can sit in the palm of your hand or comfortably in your pocket.
A Popular Choice
Some of the more popular guns that can be found today are the Kel Tec P-32 and the Walther PP. While the projectiles are less lethal than other self-defense cartridges, the .32 ACP can still get the job done.
In fact, it finishes the job many times over the years. It’s the weapon of choice for European police.
Much in the same way, a .22LR can kill a human being with correct shot placement, so can a gun in .32 ACP kill with shots in the proper place. It gets even better in terms of a modern bullet and powder technology with hotter loads and bigger projectiles.
.32 ACP Capable Round
You’d always want to go with the most capable round you can accurately place on target, in a gun that you can handle. Most people falsely think that just because it’s a small cartridge that it mustn’t produce a lot of felt recoil. They also seem to think that the biggest is always the best.
Unfortunately, if you can’t hit your intended target, the biggest is not the best. Having said all of that, with a cartridge this small, you’d likely need to unload an entire magazine into your attacker to get them to back off.
Even then, they may only die from their wounds after they bleed out, and not instantly. The 25th president of the United States of America, William McKinley, died from gangrene after he was shot twice in the chest with a .32 ACP.
Also, when you realize just how small many of these little guns are, it doesn’t really matter what size the projectile is because they don’t have anything to hold on to in order to contain any amount of recoil. Again, the best idea is to always go with what you can train with, that also just happens to be able to put an attacker down.
Other Things to Consider
Perhaps more importantly than what you’re shooting or the amount of felt recoil you’re getting is reliability. I’ve heard many .32 ACP rounds don’t cycle anything but ball ammo. There are two considerations here, and I haven’t made up my mind on this.
If the projectile is too small, an expanding bullet may be a waste because it won’t create a deep-enough wound channel. On the other hand, FMJ (ball ammo) won’t expand and will cause more penetration with a narrower wound channel.
What Is an Expanding Bullet? These are projectiles that will expand once they hit an object or surface such as a body.
For such a small projectile, I’m not sure which is best, but I’m leaning towards deeper penetration over a limit in wound channel. Please chime in below and leave a comment containing your thoughts on the matter.
If you ever decide to purchase a gun chambered in .32 ACP, make sure you do your diligence by making sure it feeds reliably in your gun of choice and make sure you’re both willing and able to put more than a few rounds into your attacker to make sure the job gets done. Otherwise, what’s the point?
Watch this video by The Ballistician about a .32 ACP penetration test through magazines:
The .32 ACP is borderline capable. It fits into that category of being too small but is just the right size for certain occasions and people. Some people carry them as a backup in the pocket, while it may be your primary weapon.
All that really matters is you’re comfortable with its performance, and you can actually hit your target with it, and it cycles properly.
