There I was about to jump in the water on the Duane this past Sunday, went to put my reg in my mouth and there's this 2-3 in metal pin drooping off to one side and the back plastic flap falling apart. I lined it all back up and re-inserted the pin but a) is this normal and b) has someone come up with a better way of securing this so that it doesn't fall apart when I'm not looking ? The reg only has about 50 dives on it. Thanks.
