So I'm not the only one with this problem! Glad to see a solution exists. If anyone is interested; I emailed Surefire and they said they would replace the mag if returned. They have a 5 yr warrantee. Still waiting on a reply back to questions like; did they make a change to correct the problem or will I just get another of the same design, if revised are redesigned ones in stock, and how long will it take to get it.
