Well, in this case the rule set is T5 and Disintegrator Pistols (which come before the oddly named "Wands") are TL-K (19). Now the Commando have Disintegrator Rifles at TL-H (17), but they are still primarily being used as a support weapon. The standard weapon listed for TL-H is the Fusion Rifle.
Magnus, I was looking for some sort of weapon list by TL and couldn't find one. Are these bits of info that you cite above hidden somewhere in T5, or are they stuff that you made for your Permatic game? As we discussed the other day, I am a complete newbie to GunMaker.
