I admit to a fondness of itty bitty mouse guns.
Ok, ok, yeah the Walther is a .22. But it fits with the theme here.
The PSP-25 I bought many years ago when I had a need for something very discrete. These are extremely well made licensed copies of the "Baby" Browning. This one has traveled many a mile in my pocket and has never missed a beat.
The Colt I got from another forum member a couple of years ago. Wonderful little gun. Quite accurate and totally reliable.
A Raven? Really? Well there's a little story that goes along with this one. I saw this on Armslist a few years ago. the owner said it wouldn't feed and to make an offer. I ended up giving him $25 for. I got it home, took it apart, turned the firing pin around the way its supposed to go and its run like a top ever since.

A week or so later, my buddy, Bob dropped by and I showed it to him. He asked what I was going to do with it? I told him I'll likely just sell it and try to make a couple of bucks. He immediately lit up. "I want it! How much?"
I offered to just give it to him, but he insisted on paying for it. So I let him give me my $25 back and it was his.
Bob passed away recently. I was helping his wife go through the safe, when I ran across it again. I knew I just had to have it back. I gave the wife 25 bucks and now its back in my safe.
Speaking of Bob's wife, among the guns she has chosen to keep for herself, two are .25s.
First is a little Taurus TP-25. She likes the small size and the easy loading pop-up barrel.
The other is a 98% Belgian made Baby Browning in the box. I told her that if she ever takes a notion to sell, I call DIBS!
