Dear Sir : I have not had a chance to fire my Ranger in the 410/45 mode as I purchased a 22mag barrel and decided to try it first. When I tried to fire it only the bottom barrel would fire. I called customer service your people were very helpful and I have been very pleased with the response to my problem. I am waiting for my gun to be returned to me with the problem resolved . I cannot be happier with the response to my problem . I thank you for your inquiry and look forward to receiving my gun to really test it out . Sincerely , Lawrence Smart
