I've been on a kick this past year replicating slightly obscure hero scifi firearms and have been thinking of modeling up a kit for Jack Deth's future pistol from Trancers. It would have a transparent barrel and I would try to give it a moving trigger with hollowed out areas for electronics.

***EDIT for Aug 5th***
Jack Deth pistol kit final cost: $315 shipped. PM if you want one. (A "finished" copy, painted and ready, is $575.)
Trigger will be an electric pushbutton (included) and the kit is hollow for those that want to add electronics (you'll have to arrange some kind of battery door or cut a port for a recharge socket). Grey parts will be done in grey professional grade engineering resin, while the tube will be brushed steel (real metal, not resin) and the emitter will be printed clear.
Here's an overlay I did
BEFORE final tweaks. You have to take into account some lens distortion, but overall it works.

And an "almost done" buildup, with mild weathering as per the original:
