If a gun is sufficeintly unique, a name is not inappropriate. That being said, I've yet to assign a name to any of my guns. Other people do that.
Case in point: The ADC Model 8, chambered for 7.62 x 39. ADC had to obtain a reamer to build it, and they said it was the only one.
Recoil is a bit snappish, to say the least. Bright, loud muzzle-blast.
Has happened more than once where someone will shoot it twice, carefully put it down, refuse to touch it again, and exclaim: "That thing's a MONSTER!!" +
I suppose it fits. It DOES bite, but has yet to draw blood, from either end. I also call it my Pocket Double Rifle, but no-one else does.
Pic is one I swiped from
American Derringer and crudely re-sized to life-size for a different project. A bit fuzzy, but the size is precise when I hold the actual gun in front of it on my screen.
