Current Gun Innovations That Will Exist in 100 Years

• 
  Caseless ammo

• Metal Storm based handguns and infantry weapons

• Binary liquid / hypergolic propellant handguns (with variable mixes for variable trajectories) - Just carry a small propellant tank and the bullets themselves.

• Rail gun / electromagnetic rifles

• Rail gun hand weapons

Personally I think the STI 2011 design is a thing of beauty

Someone mentioned improved plastic cases. Didn't someone make a totally plastic shotgun hull years ago? Was it a company called Wanda? What happened to it? A few years ago someone was making a part brass-part ceramic cased 5.56 round. What happened to it? Just curious.

Variable trajectory handguns? I don't get it. A variable trajectory shotgun maybe makes sense, but I don't get the handgun.
