History
John Browning engineered a number of modern semi-automatic pistol mechanisms and cartridges. As his first pistol cartridge, the .32 ACP needed a straight wall for reliable blowback operation as well as a small rim for reliable feeding from a box magazine. The cartridge headspaces on the rim.[6] The cartridge was a success and was adopted by dozens of countries and many governmental agencies.
When the .32 ACP cartridge was introduced, it was immediately popular and was available in several blowback automatic pistols of the day, including the
The .32 ACP has been chambered in more handguns than any other cartridge. Between 1899 and 1909,
Heckler & Koch produced the HK 4, their first handgun, in 1967. 12,000 HK 4 pistols were produced in .32 ACP for the German police and other government agencies.
Several long guns have been chambered in .32 ACP, from the Tirmax and Dreyse carbines to the

Performance
The .32 ACP is compact and light. While some believe it has marginal
It offers more velocity and energy than the .32 S&W, which was a popular round for pocket defensive revolvers at the time of the .32 ACP's development. Although with lighter bullet weights, the .32 ACP also compares favorably to the .32 S&W Long in performance. Some European 73 gr (4.7 g) .32 ACP loads provide similar performance to the .32 H&R Magnum 77 gr (5.0 g) lead flat point and 90 gr (5.8 g) lead semiwadcutter.
Even though the .32 ACP is capable of killing small game, most handguns chambered for this round utilize fixed sights and are designed for use against human-sized targets at fairly close range, which greatly limits their utility as hunting handguns.
.32 ACP is one of the most common calibers used in veterinary "humane killers", such as the Greener humane killer.
In Europe, where the round is commonly known as the 7.65mm Browning and features a different rimsizing, .32 ACP has always been more widely accepted than it has in America, having a long history of use by civilians, law enforcement personnel, and security forces, along with limited issue by military forces.
Today the cartridge has an increased popularity in the United States due to modern compact
