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! http://www.patreon.com/ForgottenWeapons http://www.floatplane.com/channel/ForgottenWeapons Cool Forgotten Weapons merch! http://shop.forgottenweapons.com Wed, 15 Apr 2026 09:28:37 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://stream.echo6.co https://stream.echo6.co/client/assets/images/icons/icon-512x512.png https://stream.echo6.co/videos/watch/363ac2eb-58f5-4fc6-b541-5431b0f09a51 All rights reserved, unless otherwise specified in the terms specified at https://stream.echo6.co/about and potential licenses granted by each content's rightholder.
