You can specially prepare bullets to deliver poisons that are normally used more subtly.
Prerequisite(s): Amateur Gunslinger or grit class feature.
This action has no chance of exposing you to the poison (as if you had the poison use class feature). Shooting a firearm loaded with a poison in this manner is a standard action that provokes attacks of opportunity and sprays out the poison in a 15-foot cone. Any creatures caught in the blast take no damage but are exposed to this poison and must each immediately attempt a save against the poison as though the onset time had elapsed.
