Michael,
I enjoyed your discussion of the Bond Arms Derringer. Ever since childhood watching The Wild Wild West I knew one day I would have to have a Derringer. I looked at all of the ones on the market. The Bond Arms is built hell for stout. I too have this gun in .45/.410 I carry it most often with a 000 buck in the lower barrel and a .45 Colt in the top barrel. I toggle the hammer to make certain that the lower barrel will fire first. My gun tends to be more accurate with the top barrel and .45s. Aleast I can make tighter groups with the top barrel. I have an inside the pants clip holster and an inside the pants pocket holster, depending on clothing on any particular day. This gun is not for the recoil sensitive. It is a wonderful companion to what ever other gun (or guns) I am carrying around the farm or around town.
