The Hi-Power name alluded to the 13-round magazine capacity; almost twice that of contemporary designs such as the Luger or Mauser 1910. The pistol is often referred to as an HP (for "Hi-Power" or "High-Power") or as a GP (for the French

Development

The 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's requirements were that the arm should be compact, have a capacity of at least 10 rounds, a magazine disconnect device, an external hammer, a positive safety, be robust and simple to disassemble and re-assemble, and be capable of killing a man at 50 meters; this last criterion was seen to demand a caliber of 9 mm or larger, a bullet mass of around 8 grams, and a muzzle velocity of 350 m/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

) 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 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 Modèle 1935 pistol

Design features

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

An extractor is a part in a firearm that serves to remove brass cases of fired ammunition after the ammunition has been fired. When the gun's action cycles, the extractor lifts or removes the spent brass casing from the firing chamber.-Overview:...

 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 by simply pulling the trigger. In contrast, a single-action pistol must be cocked manually before the first shot, either by thumbing the hammer back, or by pulling the slide to the rear and releasing it. In common with the M1911, the Hi-Power is therefore typically carried with the hammer cocked and the safety catch on (a carry mode often called cocked and locked in the USA 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. 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 reengage those in the slide.

The Hi-Power has two flaws: The standard trigger pull is heavy, especially for a single-action pistol. This disadvantage is a consequence of the Hi-Power's magazine safety design, which was initially added to the model to meet the requirements of the French military in 1935. The standard Hi-Power magazine safety is connected to the trigger and is released by a plunger pressing on the surface of the magazine. This action of the plunger on the magazine adds tension to the trigger pull, and the required force to operate this feature adds resistance as well. This problem is often resolved by removing the magazine safety entirely, thus voiding the pistol's warranty, or by polishing the interface surfaces between the safety plunger and the magazine. After-market
After-market (general)

 trigger springs with reduced tension are also available to improve the trigger pull.

In addition, 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. Many HP owners fix this problem 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.

Nevertheless, its ability to hold 13 rounds of ammunition, nearly double that of the Colt M1911 made it very desirable as a military-issue pistol.

Variants

Genuine Browning Hi-Power P35s are still manufactured by FN Herstal of Belgium and Portugal, and under license 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 & USA, 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.
  • The original P35, as noted earlier, featured an internal extractor. During World War II, it was manufactured by Inglis of Canada for Allied use, and by FN in occupied Belgium for German use. Most Canadian P35s were manufactured with a parkerized finish, while most P35s manufactured in occupied Belgium had a blued finish. In 1962 the internal extractor was replaced with a more durable and reliable external extractor alongside other modifications, including a 2-piece barrel and modifications to the locking system for improved durability. Later barrels and frames are not interchangeable with earlier ones.
  • The L9A1, was the British designation for the military version of the post-1962 Hi-Power, and is marked 'Pistol Automatic L9A1' on the left side of the slide. It started to replace Inglis variants in British service from the late 1960s, and the two types remained in service together until the Inglis variants were finally retired in the late 1980s. It is still in service with the UK military forces, although now fitted with the more ergonomic Mk2 ambidextrous safety and grips. The L9A1 was also widely used by other Commonwealth armed forces. The Hi-Power was the pistol of choice for the British Special Air Service

P35s were first imported into the USA in 1954 – the USA civilian market P35s had the 'Browning Arms Company' stamp on the left side of the slide (to meet the import requirement for USA sales). These P35s lack the provision of the lanyard ring – the left side pistol grip for a Mark I is fully covered unlike those produced for military and law enforcement use.

Only Hi-Powers specifically built for these rounds should be used to fire them. The pistols manufactured for these two rounds are easily identified by examining the left side of the slide – a groove is machined into the side of the heavier slide to allow clearance for the slide release. Genuine FN-produced P35s (either FN (Europe/international) or Browning (USA) for the civilian market will have a 245-prefix serial number. Some Hi-Power variants (Type 65, Type 73) incorporate production changes e.g. spur hammers (commonly seen for 1971–present civilian market P35s) and/or 2-piece barrels (1965–present). The 'Type 73' variant (with an elongated barrel bushing) of the Mark I was produced into the late 1980s (to 1987) by FM Argentina when Mark II production commenced in the early-mid 1980s (Belgium).

The BDA model is double action, and the DAO model is "double action only," both versions differing from the usual single-action operation of the P35. These designs have been marketed as the HP-DA and BDA. The DA and DAO models retain many features of the P35, and both are available in full-sized and compact versions. Performance of these models is consistent with FN's high standards. These models resemble the P35, but the most distinguishing feature is the extended SIG-Sauer style trigger guard. Many parts are interchangeable with the P35, but the magazines (although similar) are not. The compact versions also utilize shorter magazines.
  • The Browning BDM
    Browning BDM
    The Browning BDM is a semi-automatic pistol designed and manufactured by the Browning Arms Company up until production ceased in 1998. Similar in appearance to Browning's P-35 model "Hi-Power" pistol, the BDM was actually a new design created to compete in service trials as a standard issue pistol...

    Model is sometimes erroneously attributed as a special model of the Hi-Power family of pistols. However, this is actually a unique pistol design only bearing an external similarity to the Hi-Power. The BDM was produced during the 1990s only in North America by Browning Arms Company

    , and not by FN. The Browning BDM (Browning Double Mode) pistol incorporates many features of the BDA model, but can be switched from double action/single action mode to "revolver" mode (DAO) by the flip of a slide mounted switch.
  • Both the DA/DAO models and the BDM model borrow features from the SIG Sauer SIG P220
    SIG P220
    The SIG P220 is a semi-automatic pistol designed in Switzerland by Swiss Arms AG . It is manufactured in Eckernförde, Germany, by J.P. Sauer und Sohn GmbH. It uses the Browning linkless cam short recoil action of self-loading with a double action trigger mechanism...

    pistols marketed under the name Browning Double Action (BDA) in the 1970s. The Beretta Cheetah has also been marketed by Browning under the name BDA 380.
  • The Rosario, FM90 and FM95 models are manufactured by FM. The Rosario is an almost exact copy of the Mark II intended for Argentine and Latin American sales. The FM90 was an export model based on the Mark II, but with a "Colt style" slide without the characteristic beveled front end. Rubberized pistol grips (similar to the Pachmayr grips used for P35s) with finger grooves were used in place of the traditional slabside wood grips. The FM95 was the current export model (until 2002) based on the Mark III, also with the "Colt style" slide. The last model, until 2010, are the M02 AR(modernized version of the M95, with a new single action system by Fabrique nationale) and the M03 AR (not dated 2003, as it would seem, actually a .40S&W version of M02 AR) with their Detective versions.
  • The Detective is a short-slide HP produced by FM. The Detective slide group is also available without the frame, and is interchangeable with other FM and FN Hi-Power P35s.
  • Fabricaciones Militares of Argentina is currently developing a double action pistol, not using the HP DA system.
