Gun Master

From publisher blurb: FIGHTING FIRE WITH FIRE Since the first person was killed in anger using a firearm, a secret society has devoted its energies to stopping the spread of criminal uses of firearms--even though they must also wield guns to do so. Its most elite agent is the Gun Master. These are the tales of Dumas Poe, the latest to carry the mantle. Gun Master presents five classic tales of crime-fighting adventure and intrigue, as well as "The Way of the Gun: Gun Master d20", which includes new talent trees and feats for the OGL Modern (and other d20 System games) that want to include a secret society of gun experts.
