as you can see it has one now. it's a weak spring too. I did take a look at my local hardware store and found nothing in comparison and they don't have copper springs. my main concern is eventually the spring breaking on me than I'm screwed!Don't know about magnets but from a lot of reviews I've seen for other types of mod like this they been recommending getting copper spring from a hardware store tends to be better quality. I know this doesn't help with magnets but something to think about.
