I got mine at Cabelas on card points so nothing for me but I believe they are around 400 bucks,
Neat thing is the derringer registers on the frame and the barrels are interchangeable and Bond offers barrels in various calibers. The most popular is the 45LC/410. Barrel interchange is similar to the Encore, break open the action, pull one screw and pop in another barrel. The entire gun is brushed stainless and comes with a trigger guard (thats removable for a true derringer appearace) and rosewood engraved grips.
You can also select which barrel discharges first. The derringer has 2 firing pins, individually engaged by a cam arrangement and it has a cross bolt safety so it don't discharge in your pocket.
Best of all, the derringer is made in Texas from domestically sourced materials.
I happen to like American made, made by American workers, firearms.
It weighs about a pound, maybe a little less and is the size of a pack of smokes so it fits nicely in your pocket. While I don't name my firearms (IMO, they are tools to me), you could call it a 'pocket rocket'.
