I'd prefer one chambered for .45 Colt / .410 shot, but will consider other calibers. Similarly, I'd prefer a model with a trigger guard, but will consider others. Will consider other top quality derringers, but mostly seeking a Bond. Please PM me with details of what you have and how much you'd like for it. Cash in hand for the right gun at a fair price. Thanks! p.s. Also have some trade items, including an antique .38 S&W revolver, a variety of expensive defensive ammo in .45 colt and .410 shot, and lots of 12 gauge shotgun ammo (Buckshot, doveshot and beanbags).
