Thx, GTX_Admin, this was exactly, what I've meant.
And yes, bluesman, you have answered my question.
My intention was to remind, the Phasers and Disruptors of Star Trek or the "Handstrahlenwaffe HM-4" (Handraygun HM-4 [if you are interested in, google for the german description an click on "pics"]) of the german 1960s TV-series "Raumpatrouille" (Spacepatrol) were very simple and plain.
But a common Heckler & Koch, or a Colt, or a Glock are much more structurized than this plain, future weapons. So I imagine, a real future-blaster must be also more structured like this poor examples.
