I have a real gun that looks almost identical to the Samurai Edge, I can even buy the parts to make them look exact on a certain website, should I choose to do so. All of this is very expensive though, not to mention real guns aren't for everyone.
As far as replicas, I found the Albert Model airsoft gun here.
Blow-Back Material: Polymer + metal Weight: 950 g Color: Black Length: 215 mm Muzzle Velocity: ~280 FPS Engine: Green Gas Manufacturer: Tokyo Marui

I couldn't find the Chris or Jill model on that website, but I'm sure this is a good start.
