The Browning Hi-Power is a single-action, semi-automatic handgun available in the 9mm and .40 S&W calibers. It was based on a design by American firearms inventor John Browning, and completed by Dieudonné Saive at Fabrique Nationale (FN) of Herstal, Belgium. Browning died in 1926, several years before the design was finalized. FN Herstal initially named the design the "High Power", which alludes to the 13-round magazine capacity, almost twice that of other designs at the time, such as the Luger or Colt M1911.

During World War II, Belgium was occupied by Nazi Germany and the FN factory was used by the Wehrmacht to build the pistols for their military, under the designation "9mm Pistole 640(b)".[6] FN Herstal continued to build guns for the Allied forces by moving their production line to a John Inglis and Company plant in Canada, where the name was changed to "Hi Power". The name change was kept even after production returned to Belgium. The pistol is often referred to as an HP or BHP,[7] and the terms P-35 and HP-35 are also used, based on the introduction of the pistol in 1935. Other names include GP (for the French term, "Grande Puissance") or BAP (Browning Automatic Pistol).

The Hi-Power is one of the most widely used military pistols in history,[8] having been used by the armed forces of over 50 countries.[1] Although most pistols were built in Belgium by FN Herstal, licensed and unlicensed copies were built around the world, in countries like Argentina, Hungary and Israel. After 82 years of continuous production, FN Herstal announced that the production of the Hi-Power would end, and it was discontinued in early 2018 by Browning Arms.[9] Although new Belgian Hi-Powers are no longer being built, clones are still being built in several countries, including India and Turkey.[10][11]

The Browning Hi-Power was designed in response to a French military requirement for a new service pistol, the Grand Rendement (French for "high yield"), or alternatively Grande Puissance (literally "high power"). The French military required that:

This last criterion was seen to demand a caliber of 9 mm or larger, a bullet mass of around 8 grams (123.5 grains), and a muzzle velocity of 350 m/s (1148 ft/s). It was to accomplish all of this at a weight not exceeding 1 kg (2.2 lb).

FN commissioned John Browning to design a new military sidearm conforming to this specification. Browning had previously sold the rights to his successful M1911 U.S. Army automatic pistol to Colt's Patent Firearms, and was therefore forced to design an entirely new pistol while working around the M1911 patents. Browning built two different prototypes for the project in Utah and filed the patent for this pistol in the United States on 28 June 1923, granted on 22 February 1927.[12][13] One was a simple blowback design, while the other was operated with a locked-breech recoil system. Both prototypes utilised the new staggered magazine design (by designer Dieudonné Saive) to increase capacity without unduly increasing the pistol's grip size or magazine length.

The locked breech design was selected for further development and testing. This model was striker-fired, and featured a double-column magazine that held 16 rounds. The design was refined through several trials held by the Versailles Trial Commission.

In 1928, when the patents for the Colt Model 1911 had expired, Dieudonné Saive integrated many of the Colt's previously patented features into the Grand Rendement design, in the Saive-Browning Model of 1928. This version featured the removable barrel bushing and take down sequence of the Colt 1911.

By 1931, the Browning Hi-Power design incorporated a shortened 13-round magazine, a curved rear grip strap, and a barrel bushing that was integral to the slide assembly. By 1934, the Hi-Power design was complete and ready to be produced. It was first adopted by Belgium for military service in 1935 as the Browning P-35. Ultimately, France decided not to adopt the pistol, instead selecting the conceptually similar but lower-capacity Modèle 1935 pistol.


The Browning Hi-Power has undergone continuous refinement by FN since its introduction. The pistols were originally made in two models: an "Ordinary Model" with fixed sights and an "Adjustable Rear Sight Model" with a tangent-type rear sight and a slotted grip for attaching a wooden shoulder stock. The adjustable sights are still available on commercial versions of the Hi-Power, although the shoulder stock mounts were discontinued during World War II. In 1962, the design was modified to replace the internal extractor with an external extractor, improving reliability.

Standard Hi-Powers are based on a single-action design. Unlike modern double-action semi-automatic pistols, the Hi-Power's trigger is not connected to the hammer. If a double-action pistol is carried with the hammer down with a round in the chamber and a loaded magazine installed, the shooter may fire the pistol either by simply squeezing the trigger or by pulling the hammer back to the cocked position and then squeezing the trigger. In contrast, a single-action pistol can only be fired with the hammer in the cocked position; this is generally done when a loaded magazine is inserted and the slide cycled by hand. In common with the M1911, the Hi-Power is therefore typically carried with the hammer cocked, a round in the chamber and the safety catch on (a carry mode often called cocked and locked in the United States or "made ready" in the UK, or sometimes called condition one).

The Hi-Power, like many other Browning designs, operates on the short-recoil principle, where the barrel and slide initially recoil together until the barrel is unlocked from the slide by a cam arrangement. Unlike Browning's earlier Colt M1911 pistol, the barrel is not moved vertically by a toggling link, but instead by a hardened bar which crosses the frame under the barrel and contacts a slot under the chamber, at the rearmost part of the barrel. The barrel and slide recoil together for a short distance but, as the slot engages the bar, the chamber and the rear of the barrel are drawn downward and stopped. The downward movement of the barrel disengages it from the slide, which continues rearward, extracting the spent case from the chamber and ejecting it while also re-cocking the hammer. After the slide reaches the limit of its travel, the recoil spring brings it forward again, stripping a new round from the magazine and pushing it into the chamber. This also pushes the chamber and barrel forward. The cam slot and bar move the chamber upward and the locking lugs on the barrel re-engage those in the slide.

Design flaws[]

The pistol has a tendency to "bite" the web of the shooter's hand, between the thumb and forefinger. This bite is caused by pressure from the hammer spur, or alternatively, by pinching between the hammer shank and grip tang. This problem can be fixed by altering or replacing the hammer, or by learning to hold the pistol to avoid injury. While a common complaint with the commercial models with spur hammers similar to that of the Colt "Government Model" automatic, it is seldom a problem with the military models, which have a smaller, rounded "burr" hammer, more like that of the Colt "Commander" compact version of the 1911. Another flaw is that the original small safety is very hard to release and re-engage. This is because when cocked, the shaft the safety turns on is under hammer spring pressure. Later versions went to a larger safety to address this issue.[14][15][16]

Military service[]

Browning Hi-Power pistols were used during World War II by both Allied and Axis forces. After occupying Belgium in 1940, German forces took over the FN plant. German troops subsequently used the Hi-Power, having assigned it the designation Pistole 640(b) ("b" for belgisch, "Belgian").[8] Examples produced by FN in Belgium under German occupation bear German inspection and acceptance marks, or Waffenamts, such as WaA613. In German service, it was used mainly by Waffen-SS and Fallschirmjäger personnel.

High-Power pistols were also produced in Canada for Allied use, by John Inglis and Company in Toronto. The plans were sent from the FN factory to the UK when it became clear the Belgian plant would fall into German hands, enabling the Inglis factory to be tooled up for Hi-Power production for Allied use. Inglis produced two versions of the Hi-Power, one with an adjustable rear sight and detachable shoulder stock (primarily for a Nationalist Chinese contract) and one with a fixed rear sight. Production began in late 1944 and they were on issue by the March 1945 Operation Varsity airborne crossing of the Rhine into Germany. The pistol was popular with the British airborne forces as well as covert operations and commando groups such as the Special Operations Executive (SOE), the U.S. Office of Strategic Services (OSS) and the British Special Air Service (SAS) Regiment. Inglis High-Powers made for Commonwealth forces have the British designation 'Mk 1', or 'Mk 1*' and the manufacturer's details on the left of the slide. They were known in British and Commonwealth service as the 'Pistol No 2 Mk 1', or 'Pistol No 2 Mk 1*' where applicable. Serial numbers were 6 characters, the second being the letter 'T', e.g. 1T2345. Serial numbers on pistols for the Chinese contract instead used the letters 'CH', but otherwise followed the same format. When the Chinese contract was cancelled, all undelivered Chinese-style pistols were accepted by the Canadian military with designations of 'Pistol No 1 Mk 1' and 'Pistol No 1 Mk 1*'.[17]

In the postwar period, Hi-Power production continued at the FN factory and, as part of FN's product range which included the FN FAL rifle and FN MAG general-purpose machine gun. It has been adopted as the standard service pistol by over 50 armies in 93 countries. At one time most NATO nations used it, and it was standard issue to forces throughout the British Commonwealth. It was manufactured under licence, or in some cases cloned, on several continents. Former Iraqi ruler Saddam Hussein often carried a Browning Hi-Power. Former Libyan ruler Muammar Gaddafi carried a gold-plated Hi-Power with his own face design on the left side of the grip which was waved around in the air by Libyan rebels after his death.[18] A Hi-Power was used by Mehmet Ali Agca during the assassination attempt of Pope John Paul II in 1981.

While the Hi-Power remains an excellent design, since the early 1990s it has been eclipsed somewhat by more modern designs which are often double-action and are manufactured using more modern methods. It remains in service throughout the world. As of 2017, the MK1 version remained the standard service pistol of the Canadian Armed Forces, with the SIG Sauer P226 being issued to specialised units along with the SIG Sauer P225. The weapon is the standard sidearm of the Belgian Army, Indian Army, Indonesian Armed Forces, Australian Defence Force, Argentine Army, Luxembourg Army, Israel Police, and Venezuelan Army, among others. The Irish Army replaced its Browning Pistols (known popularly as BAPs, or Browning Automatic Pistols) with the Heckler & Koch USP in 2007. From 2013 the British Army is replacing the Browning with the polymer-framed Glock 17 Gen 4 pistol, due to concerns about weight and the external safety of the pistol.[19]

In 2018, FN ended production of the Hi-Power.[20] The Hi-Power is still being produced under license by the Ishapore Rifle Factory in India, and unlicensed copies are still being built in other countries, such as Turkey.[21][22]

Specifications of the Mk I[]

Genuine Browning Hi-Power P-35s were manufactured until 2017 by FN Herstal of Belgium and Portugal and under licence by Fabricaciones Militares (FM) of Argentina. The Hi-Power remains one of the most influential pistols in the history of small arms. It has inspired a number of clone manufacturers (including Charles Daly of the Philippines & the US, FEG of Hungary, Arcus of Bulgaria, IMI of Israel, and others). Many modern pistols borrow features from it, such as the staggered column high-capacity magazine, and the Browning linkless cam locking system (which on modern pistols is often simplified so that the barrel locks into the ejection port, meaning the barrel and slide do not have to be machined for locking lugs). Until recently, FEG made an almost exact clone in 9mm and .40 S&W, but the company now manufactures a version with modifications to the barrel, linkage, and slide stop that are incompatible with genuine Hi-Powers. Arcus has also superseded its Arcus 94 Hi-Power clone with the Arcus 98DA, a model that draws heavily from the Hi-Power but is capable of double-action operation.
