Gunslingers have mastery over a wide variety of weapons and if left unchecked can dominate the battlefield. Where they differ though, is their focus. Where other fighters tends to focus on traditional arms - the sword, the shield, the bow - the gunslinger puts their efforts to mastering firearms.

Professional Gunfighters, specializing in solving problems, either ones of their own, or if compensated well enough others peoples problems.
