From Marvel Comics The Punisher Armory No 2
870 Magnum:
“Automatic Weaponry, out of Tennessee. has put together a fine convincer. Using Remington’s 870 Magnum receiver and adding some neat details of their own. this little go-devil is only 24% inches long, and it delivers. I thought, finally l could trust a “sawed-off” under my arm.
I’d dreaded the day when they designed a good one; because I’d have to dig out the leather and tools and make a serious concealed shoulder rig. It is a bit bulky, but with judicious padding, several of my better jackets wouldn’t draw a second glance from a cop.”
