Sorry for asking such a stupid question but what does the phrase "have trigger, will travel" mean? (I'm not a native english speaker..)

It's not a stupid question, these lyrics are very strange and I can't for the life of me get my head round them. So many thourghts at one.

Have trigger, will travel implies a bounty hunter. "Have Gun Will Travel" was an American western television series about such a guy. I insist this song is about a zombie outbreak and the subsequent struggle to survive in a post-apocalyptic world.
