The Monster Hunter International book series by Larry Correia is a favorite of mine.  The basic premise of the story is that all the various monsters and magical creatures from fiction really do exist and the government pays private military companies bounties for killing them.  The story follows a character that happens to be a successful 3 Gun Competitor as he moves into the world of professional monster hunting.  All three books in the series have been very fun to read.  Its as if you are reading an action movie because the pace rarely slows down.  Firearms enthusiasts and gun culture people will especially appreciate Larry’s novels; Larry is a gun guy himself having formerly run a gun shop, participated in the action shooting sports, and instructed firearms classes.  The detail and accuracy of the way firearms are portrayed in his novels is a rare treat for gun people to read.

Larry is currently working on the fourth novel in the series, and it begins at the monster hunter equivalent of SHOT Show.  As such, more MHI teams, government agencies, and private military companies are to be featured in it.  Larry posted a design a patch contest last month, and voting is now open.  The winner gets a mention in the next novel.

Here is my submission for a private monster hunting company:
