Bond Derringers are probably some of the nicest derringers out there right now.
They are built well and reliable. I have owned the snake slayer and it was a very nice piece of craftsmanship!
They have interchangeable barrels which is cool because you can easily swap from a .22lr through .45. Accessories and holsters are easily available through the company and they have some great reviews.
Now for a pocket pistol, I would probably look else where. One the Bond Arms is a fairly large and heavy piece, and with a 2 shot capacity-well....
With everyone jumping on board and producing pocket pistols, there is just so much more to choose from at a reasonable price.
I'm with doglb. That's a very cool little Derringer, but now that everybody's jumped on the subcompact and micro-pistol market, there are a variety of choices available for around the same size and price- with 4X the ammo capacity...
I think every collection ought to have a Derringer, but they are not the most practical defense weapon you can get your hands on.
In plain English, two shots is just not enough.
