@Mr.ScottKennedy, alright that's your opinion. :)

But I think its not too much of stretch. The shotgun video is just a proof of concept. Presumably by 2025, they would be able to make things more compact. It's not anything special at all with the firearm itself, just with the special FRAG-12 round. Here's another video, this time with pistol. Now, I don't know if the 'explosion" is merely a pyrotechnic display but here have a look if you like :)

explosive? (first shot at aroun 1:20)
