What the f***???

So I have this wall of cupboards in my kitchen which reach almost to the ceiling. I was up on a stepstool today, putting a few things in the top cupboard, and I found this little black zippered pouch.

I thought maybe it was a tool kit, but it was shaped like half a heart.

I got down off the stepstool, unzipped the black pouch, and my stomach fell to the floor. Here's the face I made:

Now what, you ask, might make me make this face?

Here is the answer, the object I found left in a cupboard in my kitchen:

That's right, it's a friggin' handgun. So many questions...Whose was it? I'm assuming the lady who owned the house before me. Did she have it to protect herself? Would she quickly jump up on a stepstool, get the gun down, and load it when there was an intruder?

And, most importantly--How do you leave your gun in a kitchen cupboard???

This is definitely the strangest thing I've ever found while moving.
