The Sixth Gun #23 (Oni Press, 2012)

Kirby Hale is a gunfighter, scoundrel, and thief... and he's not accustomed to losing. He may be reeling from his dalliance with Becky in New Orleans, but now he's working for the sinister Missy Hume, and failure is not an option! Saloon girls, stagecoach robberies, oracles, and a heaping helping of smarmy charm--Kirby is hot on the trail of the magical six-shooters, but what he uncovers may be more than a rogue can handle.
