In "Foreign Agent" by Brad Thor, the protagonist, Harvath, begins his preparation by extracting a customized Palafox 9mm SIG Sauer P226 pistol. This firearm features distinctive sand-colored aesthetics and advanced TRUGLO Tritium/Fiber-Optic Day/Night sights, ensuring quick target acquisition in any lighting scenario. The design is optimized with parts of the slide milled away to enhance weight management, reduce muzzle flip, and improve control during firing.

Alongside the pistol, Harvath gathers essential gear, including a Sticky-brand inside-the-waistband holster, spare magazines, and multiple boxes of TNQ frangible 9mm ammunition. This careful selection of equipment reflects a strategic approach to being well-prepared for any potential challenges he may face, highlighting the significance of both technology and training in his line of work.
