|“Although she has been at my side more often than my partner, I have never once had to draw her from her resting place on another. That was before I ever came to this accursed cesspool of a settlement. Civilization be damned, this town would be better off burning to the ground.”|
|—Detective Rembrandt, upon inspecting the weapon for the first time in-game|
The SIG Sauer P239 is a model of semi-automatic pistol carried by Detective Flint Rembrandt while off duty as his concealed carry firearm. Having been specifically designed for use in law enforcement, it has a DAK (Double Action "Kellerman") trigger system and comes with three magazines, with 7 rounds each.
Despite that he carries the weapon alongside his off-duty handgun as well, the two are not actually used in conjunction with each other; Detective Rembrandt is "too old for raw dogging". It has less firepower but fires faster than his off-duty weapon, the Smith & Wesson Model 5906.
