Leaving aside the previous replies, which are all correct, if you really want a derringer, Bond is the one to get. It is IMO the only one worth getting--others are cheaper and that is what you get--cheaper. It is heavy--as heavy as a lightweight 38, but it is small--that cannot be denied. It is also a "load" when trying to fire it, particularly if you opt for bigger calibre.The Bond also has a few barrel changes you can buy so you can effectively have the derringer in 45/410, or other mixes of calibers. If you are buying because it is a derringer--this is the one. If you are buying for small defense, you are better off with "regular" firearms that are becoming smaller and lighter each day.
