This is a great pistol, I am a former and retired Law enforcement officer. I wish I had this derringer to carry, back in the day. I am 68 hrs old, I have had it for 2 mo., and I carry it every where, spoke to Joe, at bonds arms, and ordered A 4.25 inch barrel. It shoots great. Thanks for a great gun. Love the 38/357 barrel..and we are ordering a twent two, pistol for my wife.. Call me if you are not sure. I will help, I believe and seen the quality of this pistol, I will buy more for my family and friends. - Eddie Fischer, JR (retired law officer)
