Chinese company Hawk Industries produces a line of pump-action shotguns for hunting and security / police purposes, which are based on US-made Remington 870 shotguns. Civilian and certain security-type models of Hawk line-up with tubular magazines are sold outside of mainland China under variety of names, often exported through the NORINCO corporation. It apears that versions of the same shotgun, but adapted for a proprietary detachable box magazines are intended mostly to government export sales, as those were demonstrated on several international Military and Police / Security exhibitions. The version of the tube-fed pump action shotgun appears to be adopted by the Chinese police (PAP) as the '18.4mm Type 97-1 Anti-riot gun' (the 18.4mm is the metric designation of 12 gauge).
Hawk pump-action shotguns are available in three basic configurations: standard configuration with fixed tubular magazine below the barrel, standard configuration with detachable box magazine, and bullpup configuration with detachable box magazine. The last modification is notorious for the fact that it has a massive horizontal forward grip, which is used to cycle the pump action but also contains an integral flash-light at the front. Box magazine fed versions employ proprietary single stack magazines made from steel. Police guns of standard layout (including Type 97-1 guns) feature rifle-type sights with blade front and tangent-type rear blades; bullpup shotgun features fixed sights built into the integral carrying handle.
