32 ACP

While the 32 ACP wasn’t the first cartridge designed for semi-auto pistols, it certainly became one of the world’s most prolific. It was designed by John Browning and was the first of his commercially successful semi-auto cartridges. Known in the U.S.A. as the 32 ACP [Automatic Colt Pistol], it is better known outside of the U.S.A. as the 7,65 Browning. There are other designations such as 7.65 Browning Short, 7.65 x 17mmSR and a few others. Most Americans will simply call it the 32 Auto and most Europeans know it as the “7,65 Browning”.

The 32 ACP is certainly not a powerhouse, but it is capable of fine accuracy. The low recoil is also a plus. The real strength of the cartridge is its longevity and the multitude of pistols chambered for it. When I refer to the multitude of pistols chambered for the 32 ACP, I’m referring not only to the vast array of models chambered for it but also the staggering total number of pistols made for that cartridge. The number of FN Model 1900 pistols produced in just the first 9 years of production exceeded half a million pistols and that is just one model of one manufacturer.

Outpost75 has far more knowledge of the 32 ACP stored in his head than I could possibly scrounge up from all the reference material I could hope to find. I will say that in my efforts to study that diminutive cartridge, I’ve gained a new respect for it.

Many people have commented about the cartridge’s ability to “punch above its weight class”. This may be a function of the projectile’s small frontal area that allows for better than anticipated penetration. Of course, its ability to operate in simple blowback actions is a huge plus. When the cartridge is loaded to its European pressure levels, it achieves its full potential.

From the early 1900’s to about WWII, American made pistols such as the Colt 1903, Savage Automatic and Remington Model 51 sold in significant numbers. There are numerous references to 32 Automatic pistols and 32 Auto ammunition in pre-WWII publications. Some from advertising, some from legal documents, some from news articles and other sources. The cartridge was clearly well known and accepted in the U.S.A.

But the American acceptance of the 7,65 Browning pales in comparison to the level it was embraced by Europeans. Just the pistol production numbers alone are amazing. The production of the model 1900 exceeded 724,000 pistols in 1910 when it was replaced by the model 1910. And that was just pre-WWI FN pistols. The Great War resulted in tremendous numbers of pistols utilizing the 7,65 Browning cartridge. In the inter-war years, the cartridge continued to thrive in Europe and makers such as Walther, Mauser, Sauer, Beretta, and many others provided solid, well-made pistols. The 7,65 Browning remained incredibly popular in Europe long after WWII.

Outpost 75 previously wrote about the usefulness of the ubiquitous 32 ACP when other cartridges would draw attention in some environments. When in Rome, do as the Romans do.

I find it interesting that as late as 1976, Beretta was introducing a new model, DA pistol, chambered for the 32 ACP [The Model 81]. More than 75 years after the cartridge was introduced, a high quality, newly designed pistol chambered for the cartridge appeared on the market. And there are the Tomcats, the Kel-Tecs and other tiny 32’s now available.

And the number of older high-quality pistols that still exist on the market is impressive. You’ll pay a premium for a pristine Colt 1903 or super nice Walther PP, but they are still out there if you want one.

If one looks at the 32 Auto in the harsh light of available self-defense cartridges, it rarely appears as a first choice. However, the cartridge clearly has been used in that capacity with some positive outcomes for the user. I knew a wise man that carried a Colt 1903, and he was extremely proficient with that pistol. He could have carried any gun he wanted for self-defense and had lots of options, but he chose to stick with that 32 Auto. I don’t think that was a bad choice for him. The cartridge has been with us for over 124 years and while it may not be my first choice for serious work, it has some great history.

I have 4 very old 32 ACP's an a modern one All are pretty accurate.... Mauser 1914
Savage 1917, an Ortgies 1920 ( Very Accurate), and an MAB model D Late WWII French,..... Also a Z-Mac Jemenez 32 which only shoot a fat .314" bullet
Nice accurate little cartridge! Actually the Mauser was my first ever handgun

I never thought much of/about the cartridge before reading various tomes by @Outpost75 myself.

I'm not real big on autos these days, but the little cartridge in a lightweight, single-shot carbine intrigues me to no end. I suppose that if I had such a single-shot. Id be very inclined to sniff out an auto-pistol to complement it.

As a young man, I was convinced that the 380 ACP was "THE" pocket pistol Cartridge. When I started reading Outpost 75's work 25 years ago, I made the comparison of the 380 and the 32.

Issue #1: Except for the Savage the 380 ACP (115% of the 32 ACP size) all 380's are the same size and material as the 7.65 pistols. You will find many broken or worn out ones compared to the 32's.

Issue #2: While the 380's have more "power" than the 32's, they lack penetration. That is a big deal in the real world where people wear clothes, sometimes heavy in the cold months.

Issue #3: Accuracy is much better with the 32 ACP, but I really don't know why. I would suspect it is the semi-rimmed case, less recoil and consistent bore diameters.

IMHO, the best 32 ACP made was the Remington Model 51. The reason is that it was designed around the 380 ACP cartridge, so is larger in all dimensions, but very flat and easy to shoot. Thanks Col. Pedersen.

I have written about my past prejudice towards the 32 ACP and fortunately I have corrected that failing.

With the advantage of hindsight, it appears the development of the 7.65 Browning was well thought out. The bullet is roughly 30 caliber, and it had a lot of contemporaries that shared that nominal diameter. There were various rimmed revolver cartridges, the 7.62 Nagant, the 7.65 Luger and others, so 30 caliber was a logical starting point. Then Browning designed the cartridge to be compatible with a simple blowback semi-auto pistol. He used a straight wall case and got quite a bit of performance out of a compact cartridge. Excellent accuracy, compatible with small blowback pistols, and better than expected penetration.

The strongest testament to the brilliance of John Browning’s design is the success of that cartridge. The 32 ACP has been produced worldwide and is still in production.

IMHO the Colt 1903 is one of the sexiest handguns ever made. A natural pointer with good ergonomics. I do wish it had better sights, but when I can see them it hits where it looks. I know where there is a pretty nice one for sale but they are asking $800. Mine is a bit finish worn but mechanically sound.

$800 for a 1903 Colt with a good finish and a GOOD bore - is a bargain in today's market.

About 15 years ago I had a 1903 that was pretty rough and went in search of a replacement. I found models with a good finish but sewer pipe barrels for $750+ but examples with a good finish AND a good barrel were well over $750 and that was 15 years ago.

I think a lot of those guns were shot with corrosive primers (particularly when foreign surplus ammo came into the country) and they were seldom cleaned properly. Good Colt 1903 barrels are getting hard to find.

I have a CZ 50 and a Beretta 81. The CZ 50 is surprisingly accurate, though a little difficult to shoot. The Beretta has yet to make it to the range with me, but I suspect it will be an easy and fun one to shoot, with the double-stack 12rd magazine. It certainly fills the hand nicely.

.32 ACP is definitely a fun little cartridge.

Did you know that the company that is making the reproduction 1903 makes new barrels and parts for the later models and you can rebuild them for about $200. I did mine about 5 years ago and wrote an article for the CBA's Fouling Shot.

I wish you hadn't mentioned this. I didn't know about these reproductions. I don't have a 1903 to rebuild, but I sure would like one of these new ones. "Fortunately", the price is high enough that I can't just get it on a whim. :)

Those Beretta Model 81 pistols are solid guns and good shooters. A bit too large to qualify as a "pocket pistol" but a lot of fun as a plinker.
This one runs flawlessly with a load derived from the excellent advice of Outpost75

An Accurate 31-075H bullet, sized to .311" with 2.2 grains of Bullseye behind it. Trots along without a care and shoots exactly where the pistol is pointed.

That 81 that I had for a while was a tack-driver. I can't recall why I sold it.

The Beretta 84 was fairly popular for a time among the shotcallers, and one of our homicide guys carried it as well. One of my riff-raff rangemaster buddies used to give him crap about 'That rat gun' and that users need to be careful about the .380 ACP because 'It can raise quite a welt'.

A little Google-fu shows that Beretta has re-intro'd this series--the Beretta 80X. Like its predecessor the 84F it has a 13 round magazine--and a California version with a 10-rounder is listed. Of course, Gavin The Magnificent has yet to bless it for sale in The Worker's Paradise.

The Beretta Models 81/84 (32ACP & 380 Auto respectively) are good pistols, but I’ve always felt they were a little large for their class. The Beretta 81 and 84 are both made for double stack magazines. And the slide is rather chunky in terms of width. Those Berettas are exceptionally reliable and seem to be quite durable as well. The 81/84 pistols are almost exactly the same length and height as a Walther PP but they are noticeably fatter.
My 81 shoots well and it is certianly fun!

Yessir.

The Beretta 81 was around for a couple years and was gone before I retired; the Walther PP x 32 ACP arrived roughly the same time the 81 did, and that Walther remains in the safe to this day. It's a good 'un.

I shed my 380s not long after my East German Makarov showed up. I cart that one around in summertime a bit, 100 grain bullets at 1075-1100 FPS are kind of light-tackle countermeasures, but it beats throwing rocks--and my running days are over.

ETA--I know that I dwell upon the social dynamics of citizen CCW more than most here. Sorry about that, but I live in a target-rich environment and Condition Orange is kinda reflexive.

In my opinion, from loading some .32 Auto, it’s fairly powerful for its size. I loaded some for use in my Single Six .42 H&R mag to see if I could. I was surprised at the power on my cast reloads.
Before I left the Army, I was at the ammo dump one day and here’s a pallet of .32 Auto ammo. Asked the guys and it was selected for disposal. When a Colonel was made a General Officer, he was issued a M1903 .32 all dolled up and a special belt/buckle as a symbol of his tank. (Recall Patton in the movie shooting at strafing German lanes with a .32 Auto)
They eventually ran out of M1903s. Frankfort Arsenal then made a special runs of chopped M1911A1s or “Officers Model”. This continued until the mid 80s when they ran out of M1911A1 frames. After this time, a newly promoted General Officer got a one time allowance for purchase of a personal weapon.
Often wonder what happened to that pallet of .32 Auto./beagle
