So a guy on YouTube has a breakdown when Sig CS tells him that the two week battery life on his Romeo1 may be all he is going to get. Someone here posted that he was told by Sig CS that the 320RX was not meant for home defense or concealed carry and the battery may only last a few weeks. Several others here have posted that they have gotten several months of battery life and the battery is still going strong. Now finally my reason for another battery life thread. The July-August issue of Combat Handguns has an article on the 320RX full size. The author wanted to know what the battery life would be so he contacted Sig. I would assume someone calling Sig for info who was writing a magazine article on the 320RX would get someone who really knows about the gun. So on page 68 of the magazine the author states that he was told the battery should last 40000 hours on medium brightness. That's 4.5 years of continuous operation according to the author.
