This gun kinda falls into the "want" category than a "need" category. I already carry a G26 and LCP2 every day so I probably wont be carrying this as a 3rd gun. Ive just always liked them and wanted one. and for the price I figured why not?
My dad years ago had a .22lr/22mag derringer. I don't remember the brand but only one barrel worked. was still fun to shoot though. I've heard the center fire guns by Cobra are built slightly better and less prone to problems vs the rim fire. I just don't want to buy one, take it out and it break in the first few shots.
I really like the Bond arms derringers, the build quality is great. however they are very expensive for what they are IMO. not saying they are not worth it in terms of materials and quality but I can buy a single stack 9 for what those cost.
