9/27/21 - This is an excellent example of a hard-to-find BTJ DA Derringer over-under pistol, chambered in 9mm. It comes with an original owners manual. It has an excellent stainless steel finish with very little sign of use. There are just tiny handling marks here and there, most noticeable on the straps and the base of the frame. Comes with excellent wood grips. The bores are both excellent and have strong rifling.
