Yep. Know it well. Outback drover’s coat, unlined. About $130 at Cabala’s. You can easily conceal a pistol-grip pump shotgun (like a Mossberg 500) or a collapsible stock CAR 15 variant of which there are many.
Surprise, surprise, surprise.
You can fit a Saiga 12 under there with the 12 round drum magazine. 12 rounds of 12gauge, ruins any rampaging mobs’ day.
