The Bond is probably the highest quality derringer type pistol made. It's all stainless steel and very well made.
With that said, it's big and very heavy, and due to the traditional shape it's very awkward to cock. The shape makes it rather easy to fumble cocking it or even to drop the gun, especially if you're in a hurry.
If you load it with .410 shot shells, load it with buckshot. A nephew fired his dad's Snake Charmer model at a close target on a plywood backer and the #6 bird shot bounced off and hit him in the face. Saved by safety glasses.
The derringer design is very obsolete because these days you can have a .357 Magnum revolver holding 5 shots or a 9mm or .40 automatic with 6 shots in a package smaller, lighter, faster to reload, and far faster and easier to use.
It has a place, but it's not good as a primary defense gun.
