The Way of the Canaanite

The Way of the Canaanite is a companion perk in the Fallout: New Vegas add-on Honest Hearts gained while Joshua Graham is a companion.

Effects
While Joshua Graham is in the player's party, any .45 Auto pistol they use has halved spread and is twice as likely to score critical hits.

This increases the crit chance of the .45 to 2x, and reduces the spread to 0.4. If you somehow managed to obtain Graham's A Light Shining in Darkness pistol, its crit chance is increased to 4x, and its spread is reduced to 0.275.
