.38 Special (pronounced "Thirty-Eight Special") is a rimmed, center-fire cartridge designed by Smith & Wesson. It is most commonly used in a revolver, although automatic pistols and some carbines also exist using this round.

Despite its name, its caliber is actually 0.357-.358 inches (9.0678 mm), with the ".38" referring to the approximate diameter of the loaded brass case. This came about because the original .38-caliber cartridge, the .38 Short Colt, was designed for use in converted .36-caliber cap-and-ball (muzzleloading) revolvers, which had cylindrical firing chambers of about .374 inch diameter, requiring "heel-based" bullets, the exposed portion of which was the same diameter as the cartridge case (see the section on the .38 Long Colt). Except for its length, the .38 Special case is identical to that of the .38 Long Colt, and to the .357 Magnum which was developed from the earlier cartridge in 1935. This allows the .38 Special round to be used in revolvers chambered for the .357 Magnum (but not the reverse, lest your pistol explode in your hand). The word calibre (British English) or caliber (American English) designates the interior diameter of a tube or the exterior diameter of a wire or rod. ... .357 Magnum Colt Python revolver .357 Magnum ammunition. ...


The .38 Special was introduced in 1902 as an improvement over the .38 Long Colt cartridge which, as a military service cartridge, was found to have inadequate stopping power during the Philippines-American War. Athough It was introduced 16 years into the smokeless powder era--France adopted the first smokeless-powder military rifle cartridge, the 8x50mm R Lebel, in 1886-- the .38 Special was originally loaded with black powder, but was offered loaded with smokeless gunpowder within a year of its introduction. The .38 Special is very accurate, in a quality revolver, produces little recoil, and remains the most popular revolver cartridge in the world more than a century after its introduction. It is used for target shooting and formal target competition, for hunting small game, and for self-defense, although in most loadings it is considered somewhat underpowered for that use. The . ...

Self defense refers to actions taken by a person to defend onself, ones property or ones home. ...


In the 1930s, heavy framed revolvers oriented toward target shooting, such as the S&W "38/44 Heavy Duty", allowed development of a higher pressure (and therefore higher power) version called the .38 Special Hi-Speed and, eventually, the .357 Magnum. These .38 revolvers, built on a larger frame originally designed for the .44 Special, survived for about three decades before the .357 revolvers outdid them in sales. Today, versions of this cartridge loaded to slightly higher pressure are available, called .38 Special +P; these are usable in .38 revolvers rated +P and in .357 Magnum revolvers. .357 Magnum Colt Python revolver .357 Magnum ammunition. ... The . ... Overpressure ammunition, commonly designated as +P or +P+, is small arms ammunition that has been loaded to a higher internal pressure than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round. ...


Because the .38 Special also works in .357 Magnum revolvers, it is popular with users of the .357 Magnum for the reduced recoil and lower noise. A number of lever action rifles are also chambered in .357 Magnum and .38 Special. A lever-action is a type of firearm which uses a lever located around the trigger guard area (often including the trigger guard itself) to load fresh cartridges into the chamber of the barrel when the lever is cranked. The most famous of such lever-action firearms are the Martini...


Performance

Due to its blackpowder heritage, the .38 Special is a low pressure cartridge, one of the lowest in common use today. By modern standards, the .38 Special fires a medium sized bullet at rather low speeds. The closest comparisons are the .380 ACP, which fires slightly lighter bullets slightly faster than most .38 Special loads, and the 9 mm Luger, which fires a bullet that is generally somewhat lighter but significantly faster. Both of the latter are usually found in automatic pistols. Yugoslavian 9 mm Kratak (9 mm Short) cartridges, FMJ. The . ... Ball and hollowpoint 9mm Luger rounds The 9 mm Luger pistol cartridge (9 x 19 mm Parabellum, 9 x 19 mm NATO) was designed by firearms designer Georg Luger. ... A handgun is a firearm small enough to be carried and used in one hand. ...


The higher-pressure .38 Special +P loads offer about 20% more muzzle energy than standard-pressure loads and places between .380 ACP and 9 mm Luger.


For example, a certain .38 Special +P loading fires a 125-grain bullet at 945 ft/s for a muzzle energy of 248 ft·lb. A standard-pressure .38 Special only makes 850 ft/s for 201 ft·lb of muzzle energy. A 9 mm Luger, by comparison, will fire a 124-grain bullet at 1140 ft/s for 358 ft·lb of energy, and a .380 ACP will fire a 95-grain bullet at 955 ft/s for 192 ft·lb of energy. The .357 Magnum will fire a 125-grain bullet at 1,450 ft/s for a muzzle energy of 583 ft·lb, or nearly three times as much kinetic energy as the same bullet produces in a .38 Special.


Experience has proven that it is reasonably effective for self-defense purposes, but only a minority of US police departments now issue or authorize use of the .38 Special revolver as a standard duty weapon, most having switched to the higher-capacity and faster-reloading automatic pistols in the more powerful 9mm Parabellum, .357 SIG, .40 S&W, and .45 ACP cartridges. It is still common in security use by guards who value the reliability and simplicity of a revolver, and by civilians for concealed-carry and police for secondary pistols because its recoil when fired from very small and lightweight revolvers is considered much more manageable than more powerful cartridges. Ball and hollowpoint 9mm Luger rounds are popular handgun ammunition. ... Side-by-side comparison to other cartridges. ...

The .38 Special +P is currently used by the Hong Kong Police Force as their standard revolver ammunition. It is issued to the vast majority of uniformed and plainclothes officers for use in Smith and Wesson M10 Heavy Barrel and Colt Detective Special revolvers. Officers serving on some specialist units are instead issued with Glock 17 and 19 pistols in 9 mm Luger.
