Firecap

A firecap is a limitation on the rate of fire of semi-automatic weapons. A true semi-auto weapon can fire as fast as you can pull the trigger and as fast as the weapon's action can physically cycle, such as the M21 EBR or the M1911. Others, however, such as the M1 Garand or the Modern Warfare 2 Desert Eagle (in single player) cannot. They instead have a preset limit on the rate of fire.

On the 360 and PS3 versions of Call of Duty 4, Call of Duty: World at War and Call of Duty Modern Warfare 2; there is a limit of approximately 1200 RPM for semi-auto weapons, although the last Call of Duty 4 patch reduced the firecap of all pistols, the G3, M14 and M21 to 444RPM. The M1 Garand has a max limit of only 444 RPM, and the Modern Warfare 2 Desert Eagle in single player and Call of Duty: World at War's .357 Magnum in Nazi Zombies are currently unclocked, but both are estimated at about 100 rounds per minute. The 44. Magnum in Mw2 can fire real fast man
