I mean the physical design of the gun, not the projectile or effect.

      • It always bugs me a bit that all ST handgun-like phasers are “Type 2”, regardless of which design. I get what they’re doing, it’s just confusing. There are more than one TOS Type 2 designs, and obv. TOS Type 2 are radically different from TNG Type 2, of which there were several variations. The toxonomist in me wishes they’d been given at least sub-types; as it is, they’re categorized by (in-universe) date of introduction. But the shows and props department were sort of all over with them, making tweaks between seasons, so it can be rough to talk about without having memory-alpha up in a window.
