you know, I bought a Davis .32 a few years back just because I thought it would be fun to shoot, plus it was inexpensive. I ended up giving that gun to my buddy for his birthday one year, and he pulls it out every now and again, and we blast away happily for a few minutes with it. The thing is, I can't hit the broad side of a barn with it, and neither can he. I don't know if it is the gun or us, but really, that gun has just become a fun little blaster, and nothing more. With that being said, I can see some real advantages to a derringer as a carry piece. When it comes to two-legged varmints, it isn't great but it's better than a sharp stick. However, as a piece to carry jogging or hiking or whatever to ward off dogs or snakes or rabid squirrels, I think it is a great solution, particularly in the case of the .410 models. Its obviously small enough to hide easily, and there are simply times when you can't carry you normal piece. Its not the best solution, but it is a good one, in my opinion.
