Dunno if I would agree with that entirely. If you look at a lot of the games you are required to pick up "clips" and replace empty ones.
Lizard: You could always put a clip in that's got some LEDs or fibre optics to give the illusion that its an "energy cell" or something, kind of like the Republic Commando rifles. You should be able to find some screenshots on the net showing what I mean.
Agreed. Not to mention that logically there must be some kind of clip or pack to replenish the weapon’s power supply. In every reference I've heard to such things in games/books/etc, these power packs are always described as being inserted (hur hur hur) in much the same way as a clip. But don’t use a toy AK-47 clip though, that may look odd .
Keep in mind that Boba's blaster has a 'hammer' and he wears an ammo belt... Also in most of the books they reference power packs as clips or magazines, though clip and magazine are not interchangable terms in modern weapons, they seem to use them throughout the star wars realm and not to mean that they contain projectiles but energy of whatever variety used by a specific weapon.
