Didn't know where else to post this. I realize most cops probably carry "Cop Top" style canisters, but I was hoping some of you had experience with flip-top. I have a few cans of Fox Labs in flip top configuration. When they were brand new, and I depressed the button WITHOUT lifting the flip top, it would not fire. Which I like. After spraying a can once or twice, that no longer is the case. I can now put my thumb in there and fire it without flipping the cap up first. Is this by design? Is the top more of a safety from pressing the button, than a true safety? It wouldn't be a big deal if I keep it in its own pocket, but if I have a lighter or something in my pocket with it, i'm scared it will get under the flip-top and fire the can. Thanks!
