Ok! I have heard some good ideas thus far!
Concepts like the "peacemaker," can be both foreboding, and catchy. However, you could always end up being an anime with guns name the Harkonnen, or the Jackal. (3 Internets to anyone who can tell me the anime I am thinking about.)
Alternatively, using the name of its inventor, then having that name be culturally relevant to the region it was created in is quite logical.
