Kel-Tec's KSG shotgun may be the most anticipated firearm of 2011, due to its unusual, innovative design. The high-capacity weapon arrives with twin 7-round magazine tubes, giving operators 15 total rounds when a shell is chambered. The KSG's short barrel and bullpup design give patrol officers flexibility when deploying it from a cruiser. View detailed photos of the weapon, and be sure to read our November "Arsenal" review.
