419:, to make pistols shoot with as little muzzle rise as possible to allow faster follow-up shots on target. A muzzle brake works by diverting gases perpendicularly relative to the barrel to reduce felt recoil. The greater the gas volume, or the pressure that gas is at, the more force the compensator or muzzle brake creates. Competitors could "feed" a compensator more gases than comparable

Most shooters, looking at the 9×25mm Dillon today, focus on the extreme velocities of which it is capable. A 115-grain bullet at 1,800 fps is more than is needed for competition. There, a 115 only needs to be going a bit over 1,500 ft/s to qualify for major power factor. Competitors in the late 1980s

Around 1987, Randy
Shelley, an employee of Dillon Precision, necked down 10mm Auto brass to 9 mm. His goal was to get as much slow-burning powder in the case as possible in order to drive a 9 mm bullet to the velocity needed to qualify for the then-IPSC major power factor of 175. The short-necked

What put an end to the 9×25mm Dillon in competition was lowering of the USPSA major power factor from 175 to 165 (160 for IPSC competition) which improved the safety and effectiveness of .38 Super (and later 9x19 "Major") loads to a point that the extra rounds that would fit maximum-allowed length

Making the 9×25mm Dillon is fairly easy. Dillon
Precision makes the necessary resizing die, and reliable reloading data is easily found. Most people use 115- to 125-grain bullets, but bullets with weights as low as 80 grains are used, too.

pistol cartridge is probably the closest ballistic twin of the 9×25mm Dillon. These cartridges are both necked-down 9 mm variants of the 10mm Auto cartridge, though they dimensionally vary.
516:: As of 2016, DoubleTap offers six 9×25mm Dillon factory ammunition loads from 80 to 180 grains. Underwood Ammo offers three 9×25mm Dillon factory ammunition loads from 90 to 125 grains.
