So yester day evening I took a drag of my sig. I sat it down. I reached over a few minutes later. Hit the fire button and nothing. The screen read check atty. Well after trying it with every atty I own and a subtank, I will not fire anything. It just says check atty. I checked the spring on the 510 and it isn't stuck. I cleaned the connection out and it wasn't even dirty. I have had this just over 2 weeks. It has never been dropped bumped it anything. I do not know what the issue could be. Anyone have this issue or have any ideas? Thanks.
