Big Army, Big Shotgun: The Soviet Union Put The KS-23 To Good Use

The huge KS-23 was designed for police and riot control officers.

Here's What You Need To Remember: The KS-23 is undeniably massive, and it is still used today. Don’t expect to get your hands on one anytime soon though. Thanks to the massive barrel diameter, the gun is banned by U.S. federal law.

The KS-23 is possibly the largest shotgun ever designed by the Soviet Union or Russia. At 23 millimeters in diameter, the KS-23 easily dwarfs the smaller but ubiquitous 12 gauge shotgun, which is 18.5 millimeters in diameter.

The huge KS-23 was designed for police and riot control officers. Rather than manufacturing new barrels, the original design incorporated cut-down 23 millimeter barrels designed for aircraft. These barrels had been rejected due to manufacturing defects which made them insufficiently robust for use in planes. However, for use in lower pressure firing, like shotguns, the barrels were deemed sufficient.

Since the barrels were originally designed to fire 23-millimeter ammunition, they were rifled, rather than smoothbore as many shotgun designs are. The shotgun was therefore classified as a carbine of sorts due to its barrel rifling. It also incorporates a pistol-style grip, rather than an older-style straight grip incorporated into many shotgun designs. 

Several variants of the big-bore gun were built, the original in the 1970s. The standard and original variant had a fixed wooden stock. Like other shotguns, shotgun shells were loaded via a three-round tubular magazine underneath the barrel. This hindered the KS-23’s capacity. With a full magazine and one shell in the chamber, the shotgun had a paltry four-round capacity. In addition to various rubber or plastic crowd dispersal rounds, 23mm gas and stun cartridges are also in use.

Later variants were improved somewhat, incorporating a removable heavy wire buttstock, and a higher capacity seven-shell magazine. There is also a civilian version of the shotgun available for purchase on Russia’s civilian hunting market that offers both various large buckshot loadings, as well as massive 23-millimeter lead slugs for taking down large game.

The North Korean Connection

Besides various policing forces and border protection services in both Russian and various Central Asian countries, the KS-23 is also in use with North Korea, though it is unclear in what capacity.

According to reports, Pyongyang does have a fair number of the shotguns, though it is unknown exactly how many. NK News reports that China exported ammunition to the Hermit Kingdom in both 2012 and in 2014. The transfer occurred without informing the United Nations, as required by UN Resolution 1874. The resolution requires a notification period of at least five days before any such transfer would take place.

Postscript
