The Secret Meaning of Jack's Shotgun in the 'Reacher' Season 3 Finale

In the Season 3 finale of Reacher, our hero Jack Reacher (Alan Ritchson) doles out his brand of hardcore justice, not just on his old enemy Quinn (Brian Tee) but also blasts anyone else who stands in his way. And, while there are a lot of different types of firearms available to Reacher, thanks to the illegal gun shipment central to the story, he doesn't choose an automatic weapon or anything fancy. Instead, in choosing his gun for the big showdown, Reacher opts for a slick shotgun. 

But this choice isn't random.
