Source-derived summary

The Armsel Striker, also known as the Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog and SWD Street Sweeper is a 12-gauge shotgun with a revolving cylinder that was designed for riot control and combat.

History

The Armsel Striker was designed by Hilton R. Walker, a Zimbabwean (formerly Rhodesian) citizen, in 1981. Walker subsequently emigrated to South Africa, bringing with him the design for the Striker shotgun. His shotgun became a success and was exported to various parts of the world, despite some drawbacks. The rotary cylinder was bulky, had a long reload time, and the basic action was not without certain flaws.

Walker redesigned his weapon in 1989, removing the cylinder rotation mechanism, and adding an auto cartridge ejection system. The new shotgun was named the "Protecta".

A copy of the Striker was made by the American gunmaker Cobray and marketed as the "SWD Street Sweeper" from 1989 to 1993.

Design and features

The Striker's most prominent feature is a 12-round capacity revolving cylinder. Due to the size of the cylinder, unlike usual revolvers which rotate the cylinder with the trigger pull, the Striker utilizes a clock spring that has to be wound manually.
