History[edit]

The .41 Action Express was designed by Evan Whildin, vice president of Action Arms, in 1986.[3] It was based on the .41 Magnum case, cut down to fit in a 9mmP frame, and using a rebated rim. Performance was compared to the ballistics of the 41 Magnum police load.[2] The .41 AE was thought to be a very attractive concept, as the rebated rim allows a simple change of barrel, mainspring, and magazine to convert many 9mm guns to 41 AE.[2]

The powerful 10mm Auto cartridge, which had been suffering from poor acceptance from its start in the early 1980s, was eventually accepted by the FBI in a reduced power, subsonic loading. Smith & Wesson then decided the 10mm Auto was too much cartridge for the reduced power loading, and that the .45 ACP sized guns that chambered it were too heavy and bulky; out of this came the .40 S&W, a shortened 10mm Auto case, designed to fit in a 9mm-sized gun, with a reduced pressure loading that allowed a lighter, easier to shoot gun.[4][5] Because most ammunition manufacturers backed the .40 S&W, there was little use for the very similar .41 AE, so production of both firearms and ammunition was soon phased out;[2] it was designated as an 'inactive' cartridge by SAAMI in January 2005.[6]

The .41 AE was doomed by circumstance to obscurity, but the concept of using a rebated rim to allow easy cartridge interchangeability was not lost. The .50 Action Express, developed by Magnum Research for the Desert Eagle pistol, uses a similar rebated rim that is the same diameter as the .44 Magnum.[7] This allows a caliber change with replacement of just the barrel and magazine.

Ballistics[edit]

The .41 AE can be ballistically similar to the .40 S&W, to the point that many reloading manuals suggest using .40 S&W load data in the .41 AE. Original IMI factory cartridges are much higher powered, pushing a 170 gr (11.02 g) bullet at 1215 ft/s. The .41AE actually outperforms the .40SW by a significant amount. Current (April 2018) production cartridges from Reed's Ammunition and Research lists the following:170 grain JHP at 1230fps; 185 grain JHP at 1180fps and 210 grain JHP at 1150fps. Old Speer reloading manuals also list 210gn JHP at 1150fps. The .40 S&W will NOT duplicate this performance.. The .41 AE uses 0.410-inch (10.4 mm) bullets, whereas the .40 S&W uses 0.400-inch (10.2 mm) bullets. However, as it lacks the backing of ammunition manufacturers in making .410 caliber bullets suited to semiautomatic pistols, the .41 AE has not achieved widespread popularity.[8][9]

Usage in firearms[edit]

There have been several firearms chambered for this cartridge, most notably the Israeli Uzi and the Jericho 941.[2] The potential for success for the 41 AE was sound, and for this reason, other manufacturers offered firearms chambered at the factory for this round. Additionally, aftermarket conversion kits were available as well.

Factory chambered[edit]

  • Uzi Carbines and pistols
  • Jericho 941/Baby Eagle Early imports had the ability to switch calibers from 9mm, 41AE and .45ACP through kits that had magazines and whole slide assemblies that were marked for each respective cartridge.

Aftermarket conversion[edit]

  • Browning Hi-Power this was only offered for the MK-I series.

In 1988, IMI also developed a 9 mm Action Express, which was a .41 AE necked down to 9 mm. It offered a much larger case capacity than the standard 9 mm case, allowing velocities that matched that of the .357 Magnum when loaded with light bullets. This move anticipated the parallel development of the .357 SIG from the .40 S&W in 1994.[2]

The .40 S&W (10×22mm Smith & Wesson in unofficial metric notation) is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester.[3] The .40 S&W was developed from the ground up as a law enforcement cartridge designed to duplicate performance of the Federal Bureau of Investigation's (FBI) reduced-velocity 10mm Auto cartridge which could be retrofitted into medium-frame (9mm size) semi-automatic handguns. It uses 0.40-inch (10 mm) diameter bullets ranging in weight from 105 to 200 grains (6.8 to 13.0 g).[4]

History[edit]

In the aftermath of the 1986 FBI Miami shootout, in which two FBI special agents were killed and five wounded, the FBI started the process of testing 9×19mm Parabellum and .45 ACP ammunition in preparation to replace its standard-issue revolver with a semi-automatic pistol. The semi-automatic pistol offered two advantages over the revolver: increased ammunition capacity and increased ease of reloading during a gunfight. The FBI was satisfied with the performance of its .38 Special +P 158 gr (10.2 g) lead semi-wadcutter hollowpoint (LSWCHP) cartridge ('FBI load') based on decades of dependable performance. Ammunition for the new semi-automatic pistol had to deliver terminal performance equal or superior to the .38 Special FBI load. The FBI developed a series of practically oriented tests involving eight test events that they believed reasonably represented the kinds of situations that FBI agents commonly encountered in shooting incidents.[citation needed]

During tests of the 9×19mm and .45 ACP ammunition, the FBI Firearms Training Unit's special agent-in-charge, John Hall, decided to include tests of the 10mm Auto cartridge, supplying his own Colt Delta Elite 10mm semi-automatic, and personally handloaded ammunition. The FBI's tests revealed that a 170–180 gr (11.0–11.7 g) JHP 10mm bullet, propelled between 900–1,000 ft/s (270–300 m/s), achieved desired terminal performance without the heavy recoil associated with conventional 10mm ammunition (1,300–1,400 ft/s (400–430 m/s)). The FBI contacted Smith & Wesson and requested it to design a handgun to FBI specifications, based on the existing large-frame Smith & Wesson Model 4506 .45 ACP handgun, that would reliably function with the FBI's reduced-velocity 10 mm ammunition. During this collaboration with the FBI, S&W realized that downsizing the 10mm full power to meet the FBI's medium velocity specification meant less powder and more airspace in the case. They found that by removing the airspace they could shorten the 10mm case enough to fit within their medium-frame 9mm handguns and load it with a 180 gr (11.7 g) JHP bullet to produce ballistic performance identical to the FBI's reduced-velocity 10mm cartridge. S&W then teamed with Winchester to produce a new cartridge, the .40 S&W. It uses a small pistol primer whereas the 10mm cartridge uses a large pistol primer.

The .40 S&W cartridge debuted January 17, 1990, along with the new Smith & Wesson Model 4006 pistol, although it was several months before the pistols were available for purchase. Austrian manufacturer Glock Ges.m.b.H. beat Smith & Wesson to the dealer shelves in 1990, with pistols chambered in .40 S&W (the Glock 22 and Glock 23) which were announced a week before the 4006.[5] Glock's rapid introduction was aided by its engineering of a pistol chambered in 10mm Auto, the Glock 20, only a short time earlier. Since the .40 S&W uses the same bore diameter and case head as the 10mm Auto, it was merely a matter of adapting the 10mm design to the shorter 9×19mm Parabellum frames. The new guns and ammunition were an immediate success,[6][7] and pistols in the new caliber were adopted by several law enforcement agencies around the nation, including the FBI, which adopted the Glock pistol in .40 S&W in May 1997.

The popularity of the .40 S&W accelerated with the passage of the now-expired Federal Assault Weapons Ban of 1994 which prohibited sales of pistol or rifle magazines that could hold more than ten rounds (cartridges), regardless of caliber. Several U.S. states, and a number of local governments, also banned or regulated so-called 'high capacity' magazines. As a result, many new firearm buyers limited to purchasing pistols with a maximum magazine capacity of 10 rounds chose pistols in the .40 S&W chambering instead of smaller-diameter cartridges such as the 9x19mm (9mm Luger or 9mm Parabellum).

The .40 S&W case length and overall cartridge length are shortened, but other dimensions except case web and wall thickness remain identical to the 10mm Auto. Both cartridges headspace on the mouth of the case. Thus in a semi-auto they are not interchangeable. Fired from a 10mm semi-auto, the .40 Smith & Wesson cartridge will headspace on the extractor and the bullet will jump a 0.142 inches (3.6 mm) freebore just like a .38 Special fired from a .357 Magnum revolver. If the cartridge is not held by the extractor, the chances for a ruptured primer are great.[8] Smith & Wesson does make a double-action revolver that can fire either at will using moon clips. A single-action revolver in the .38–40 chambering can also be modified to fire the .40 or the 10mm if it has an extra cylinder. Some .40 caliber handguns can be converted to 9mm with a special purpose made barrel, magazine change, and other parts.

Cartridge dimensions[edit]

The .40 S&W has 1.25 ml (19.3 grains H2O) cartridge case capacity.

The common riflingtwist rate for this cartridge is 406 millimetres (16.0 in), 6 grooves, ∅ lands = 9.91 ;mm, ∅ grooves = 10.17 mm, land width = 3.05 mm and the primer type is small pistol.[4] According to the official C.I.P. guidelines, the .40 S&W case can handle up to 225 megapascals (32,600 psi) piezo pressure. In C.I.P.-regulated countries every pistol/cartridge combo has to be proofed at 130% of this maximum C.I.P. pressure to certify for sale to consumers.
The SAAMI pressure limit for the .40 S&W is set at 241.32 megapascals (35,001 psi) piezo pressure.[9]

Performance[edit]

.40 S&W Jacketed Flat Point cartridge from the side.

The .40 S&W cartridge has been popular with law enforcement agencies in the United States, Canada, Australia and Brazil. While possessing nearly identical accuracy,[10] drift and drop as the 9mm Parabellum, it also has an energy advantage[11] over the 9mm Parabellum[12] and .45 ACP,[13] and with a more manageable recoil than the 10mm Auto cartridge.[6] Marshall & Sanow (and other hydrostatic shock proponents) contend that with good jacketed hollow point bullets, the more energetic loads for the .40 S&W can also create hydrostatic shock in human-sized living targets.[14][15]

Based on ideal terminal ballistic performance in ordnance gelatin during lab testing in the late 1980s and early 1990s, the .40 S&W earned status as 'the ideal cartridge for personal defense and law enforcement'.[7][16] Ballistically the .40 S&W is almost identical to the .38-40 Winchester introduced in 1874, as they share the same bullet diameter and bullet weight, and have similar muzzle velocities.[17] The energy of the .40 S&W exceeds standard-pressure .45 ACP loadings, generating between 350 foot-pounds (470 J) and 500 foot-pounds (680 J) of energy, depending on bullet weight. Both the .40 S&W and the 9mm Parabellum operate at a 35,000 pounds per square inch (240 MPa) SAAMI maximum, compared to a 21,000 pounds per square inch (140 MPa) maximum for .45 ACP.[18]

.40 S&W pistols with standard (not extended) double-stack magazines can hold as many as 16 cartridges. While not displacing the 9mm Parabellum, the .40 S&W is commonly used in law enforcement applications in keeping with its origin with the FBI. Select U.S. special operations units have available the .40 S&W and .45 ACP for their pistols. The United States Coast Guard, having dual duties as maritime law enforcement and military deployments, has adopted the SIG SauerP229R DAK in .40 S&W as their standard sidearm.

The .40 S&W was originally loaded at subsonic velocity (around 980 ft/s (300 m/s)) with a 180 grains (11.7 g) bullet.[16] Since its introduction, various loads have been created, with the majority being either 155, 165 or 180 gr (10.0, 10.7 or 11.7 g).[19] However, there are some bullets with weights as light as 135 gr (8.7 g) and as heavy as 200 gr (13.0 g).[20] Cor-Bon and Winchester both offer a 135 gr (8.7 g) JHP and Cor-Bon also offers a 140 gr (9.1 g) Barnes XPB hollow-point. Double Tap Ammo, based out of Cedar City, Utah, loads a 135 gr (8.7 g) Nosler JHP, a 155 gr (10.0 g), 165 gr (10.7 g) and 180 gr (11.7 g) Speer Gold Dot hollow-point (marketed as 'Bonded Defense'), a 180 gr (11.7 g) Hornady XTP JHP, and three different 200 gr (13.0 g) loads included a 200 gr (13 g) Full Metal Jacket (FMJ), a 200 gr (13 g) Hornady XTP JHP and Double Tap's own 200 gr (13 g) WFNGC (Wide Flat Nose Gas Check) hard cast lead bullet; the latter specifically designed for hunting and woods carry applications.

Case failure reports[edit]

Beretta 96 Feed Ramp

The .40 S&W has been noted in a number of cartridge case failures, particularly in older Glock pistols due to the relatively large area of unsupported case head in those barrels, given its high working pressure.[21][22] The feed ramp on the Glock .40 S&W pistols is larger than on other Glocks, which leaves the rear bottom of the case unsupported, and it is in this unsupported area that the cases fail. Most, but not all, of the failures have occurred with reloaded or remanufactured ammunition.[23] Cartridges loaded at or above the SAAMI pressure, or slightly oversized cases which fire slightly out of battery are often considered to be the cause of these failures,[23] which are commonly referred to as 'kaBooms' or 'kB!' for short.[23] While these case failures do not often injure the person holding the pistol, the venting of high pressure gas tends to eject the magazine out of the magazine well in a spectacular fashion, and usually destroys the pistol. In some cases, the barrel will also fail, blowing the top of the chamber off.
