I can't comment on the .22lr Cobra derringers from experience, but I do have their .38spcl derringer, it's ugly as a dog's butt, but it gets the job done. It is what it is for sure, a gun with under 3" from cartridge rim to muzzle. Mine shoots pretty well, I can hit milk jugs at 15-20ft nearly every time (probably 90% or better) one handed, but I usually have the good grace of knowing which bbl is going to fire, and being able to adjust my hold over accordingly...if you're wanting one for defense or something, you might not know which bbl's up, nor care...however by the time you pull a derringer, they're so close you can smell them anyway.
