The Colt Peacemaker is a potent symbol of the destructive patriarchal legacy that defines the Porch family, as well as the staple of violence that defines action in the Western genre.

As a family heirloom passed from father to son, the ironically named Peacemaker is the very instrument of a self-consuming cycle of vengeance. The pistol is described as more than a weapon; it is a "reverential object, part artifact, part totem, and no doubt part killin machine" (94), indicating its sacred status within the Porch family’s toxic value system. It is the physical embodiment of the belief that power, honor, and identity are maintained through force and domination. Russel Porch’s attempt to steal the Colt is a misguided effort to claim his inheritance and prove his worthiness within this violent lineage, an act that ironically leads directly to his death at the hands of his own father. Crucially, Old Porch dismisses Russel when he reports the theft of the two horses; he only becomes angry when Russel accidentally reveals that Kalin and Landry have the Colt. It later becomes revealed that Egan feels entitled to own the Peacemaker, following many attempts to prove himself to his father as a living instrument of violence. In this way, the Colt proves itself a more fundamental artifact of the Porch family’s power than their livestock or businesses do.

The gun, meant to signify patriarchal succession, instead becomes the catalyst for the family's implosion. In the possession of Kalin March and Landry Gatestone, the Colt is turned against the family who have been using violence to maintain their dominance over the land in Orvop and its peoples. While the “curse” Allison places on Kalin prevents him from using the Colt for most of the novel, he sees its eventual use in the climax as the defining act that will seal the fates of the horses he has been charged with rescuing, even if it means severing his empathetic connection to horses. By choosing to use the gun, Kalin effectively sacrifices that connection in order to save Navidad, Mouse, and Tom’s spirit. This underscores the damning nature of the gun, even though it functions as a staple in most Western stories.
