Introduction

The KS-23 is a shotgun of Soviet origin. It was developed for law enforcement use in the 1980's. The name KS-23 stands for Karabin Spetsialniy, which is Russian for special carbine. The number 23 refers to the 23mm diameter of the barrel, which makes it one of the most powerful tactical shotguns

Design

The KS-23 has a standard pump-action shotgun design plus some uncommon features. The barrels are derived from rejected 23mm aircraft cannon barrels. The rifling allows for an exceptional range with slugs and cannister ammunition such as tear gas. Below the barrel there is a tubular magazine that doubles as the rails for the polymer pump slider. A fixed wooden stock is fitted.

Firepower

The KS-23 fires its own range of 23mm ammunition that includes buckshot, slugs, tear gas and other special rounds. The magazine capacity is 3 rounds plus 1 in the chamber. Slugs have a maximum range of 100 to 150 meters.

Users

The KS-23 is used by Russian law enforcement and those of former Soviet states. It is being supplemented by more modern 12ga shotguns but remains in active use.
