Developed by Heckler & Kock and adopted by the German army in 1976, the P11 has become the de facto underwater pistol for all NATO militaries. It is an electrically-fired pepperbox style pistol with five barrels. Each barrel is preloaded and the barrel clusters are easily swapped – and must be returned to H&K for reloading. Two different types of ammunition are made; DM91 bullets for firing in air and DM101 flechette darts for firing underwater.

Many thanks to Andy at H&K for inspiring me to do this video, and to the British Royal Armouries for giving me access to this P11 to film!
