Well, it wouldn't make sense to make a Grineer-designed weapon a Prime weapon (i.e Viper Prime).

Also, it wouldn't make sense to make a Corpus-designed weapon a Prime weapon (i.e Dera or Supra Prime).

Tenno are pretty much (correct me if I'm wrong) the descendants of the Orokin. All the weapons that are don't incorporate Grineer or Corpus design are Tenno made (i.e Scindo, Paris, Kunai). Warframes are also of Orokin design, and the Tenno are designed to use these Warframes not only as an exoskeleton, but also as a lethal weapon, if need be.

Hopet that answers your question.
