The HK P11 is a Heckler & Koch pistol designed as an underwater firearm.
Design
Since ordinary-shaped rounds are inaccurate and have a very short range when used underwater, this pistol fires steel darts about 10 centimetres (3.9 in) long. It has five barrels, each of which is loaded with a cartridge, giving the gun a pepper-box appearance, and it is electrically ignited from a battery pack in the pistol grip.[1] After firing all five cartridges, the barrel unit must be sent back to its manufacturer for reloading.[2] It is very similar to its predecessor, the Mk 1 Underwater Defense Gun. In the past, Heckler & Koch has denied knowledge of its existence.[3]
This firearm is somewhat bulkier than its Soviet counterpart, the SPP-1 Underwater Pistol, but it has five barrels, as opposed to the Soviet firearm which has four. However, the SPP-1 does not need to be sent back to the manufacturer to be reloaded.
