A Deringer is a derringer

I was writing about a feisty old west heroine who carried a pistol in her pocket, a derringer, of course, because I’d heard of them. When my critique partner asked if I spelled the word correctly, I looked up the answer. And, in that research, I found all kinds of fascinating history about pocket pistols.

They have been around since . . .
