After reading all of the rave reviews on the D60, I finally bought one. Other than being slow to load, it seemed to work fine in practice. The first time I used it in a match, I had an issue twice where the loading lever popped up and obviously the rounds refused to feed. I finally resorted to putting a rubber band around the magazine body and latch to hold it in place. Has anyone else had this problem? In spite of the many complaints against the Surefire, I have never had any issues with the ones that I have.
