Digging in the pistol safe some more.
When I was carring, I had this for my boot gun. A friend of mine who had a boot repair shop took one of my Wellington dress boot (In Texas they are you go to town boots) and made me a pocket for it to fit inside my boot. You could carry it and not even notice it was there. I never had to use it, but it was good to have a back up.
It was a good shooter for a 22lr, As long as I used copper jacketed ammo it never jammed. Yep! it is very small, Holds 9 rounds of 22 LR.(10 if you carry one in the chamber) It was made by Auto Nine Corp. Made in the U.S.A. This is the only one I have ever seen. It is a little heavy for its size. All steel, milled ( except for the plastic grips). It was not a cheap pistol at the time when I bought it, but I ordered it to see if they would sell. It didn't so I just kept this one. Too many really cheap pistol at the time for sale on the market.
I added the Q-tip in the picture for size comparison.
It is not for sale.
I did a search and it looks like Wilkinson Arms made it also and was called the "Sherry" after his daughter.
