History

The .44 Remington Magnum, or simply .44 Magnum, is a large-bore cartridge originally designed for revolvers. After introduction, it was quickly adopted for carbines and rifles. Despite the ".44" designation, all guns chambered for the .44 Magnum case, and its parent case, the .44 Special, use bullets of approximately 0.429 in (10.9 mm) diameter.
 
The .44 Magnum is based on a lengthened .44 Special case, loaded to higher pressures for greater velocity (and thus, energy). The .44 Magnum has since been eclipsed in power by the .454 Casull, among others; nevertheless, it has remained one of the most popular commercial large-bore magnum cartridges. When loaded to its maximum and with heavy, deeply penetrating bullets, the .44 Magnum cartridge is suitable for short-range hunting of all North American game—though at the cost of much recoil and muzzle flash, when fired in handguns. In carbines and rifles, these are non-factor.

The .44 Magnum cartridge was the end result of years of tuned handloading of the .44 Special. The .44 Special, and other large-bore handgun cartridges, were being loaded with heavy bullets, pushed at higher than normal velocities for better hunting performance. One of these handloaders was Elmer Keith, a writer and outdoorsman of the 20th Century.
 
Elmer Keith settled on the .44 Special cartridge as the basis for his experimentation, rather than the larger .45 Colt. At the time the selection of .44 caliber projectiles for handloaders was more varied, and the .44 Special case was smaller in diameter than the .45 Colt case. In revolvers of the same size, this meant the .44 caliber revolvers had thicker, and therefore stronger, cylinder walls than the .45. This allowed higher pressures to be used without risk of a burst cylinder.
 
Keith encouraged Smith & Wesson and Remington to produce a commercial version of this new high pressure loading, and revolvers chambered for it. While S&W produced the first prototype revolver chambered in .44 Magnum, the famous Model 29, Sturm, Ruger actually beat S&W to market by several months in 1956 with a .44 Magnum version of the single action Blackhawk revolver. The exact reason for this is unclear. One version says a Ruger employee found a cartridge case marked ".44 Remington Magnum" and took it to Bill Ruger, while another says a Remington employee provided Ruger with early samples of the ammunition.
 
The .44 Magnum case is slightly longer than the .44 Special case, not because of the need for more room for propellant, but to prevent the far higher pressure cartridge from being chambered in older, weaker .44 Special firearms, thus preventing injuries and possible deaths.

 
The .44 Magnum was an immediate success, and the direct descendants of the S&W Model 29 and the .44 Magnum Ruger Blackhawks are still in production, and have been joined by numerous other makes and models of .44 Magnum revolvers and even a handful of semi-automatic models, the first being the .44 Automag, produced in the 1960s. The debut of the Clint Eastwood star-vehicle film Dirty Harry (1971) prominently featuring the S&W M29 (or M629) contributed to that model's popularity (as well as the cartridge itself).
 
Ruger introduced its first long gun, a semi-automatic carbine chambered for the .44 Magnum, in 1959, and Marlin followed soon after with a lever action model 1894 in .44 Magnum. Having a carbine and a handgun chambered in the same caliber is an old tradition; the .44-40 Winchester was introduced by Winchester in a lever action in 1873, and Colt followed in 1878 with a revolver chambered in the same caliber. The .38-40 Winchester and .32-20 Winchester were also available chambered in both carbines and revolvers, allowing the shooter to use one type of ammunition for both firearms.

 
Although improved modern alloys and manufacturing techniques have allowed even stronger cylinders, leading to larger and more powerful cartridges such as the .454 Casull and .480 Ruger in revolvers the same size as a .44 Magnum, the .44 Magnum is still considered a top choice today. In 2006, to commemorate the 50th anniversary of the .44 Magnum, Ruger introduced a special 50th anniversary Blackhawk revolver, in the "Flattop" style.

Singleplayer/Spec-Ops

The .44 Magnum is unlocked at level 20 in Survival. It can be bought from the Weapons Armory for $250.

Multiplayer

The .44 Magnum is unlocked at Level 46 in Modern Warfare 3's multiplayer. It has slightly less damage than its Modern Warfare 2 counterpart, but has the same amount of recoil. Though the gun works well in close quarters combat, it suffers in mid-long ranges due to its low damage and high recoil at range, where at maximum range, it can take 5-6 shots to kill an enemy depending on where the bullets hit.
