The Space:1999 ray gun ( obviously). I was never really into toy guns as a kid, and it was much easier to just stick a couple of fingers out and go "Peow!Peow!" anyway, but this plastic beauty was cool. I just liked the fact that it looked different to the standard raygun, and much better than a phaser. Heresy, I know. Long since gone to the Great Jumble Sale In The Sky. Sigh!
