Are Binary Triggers Legal in Delaware?

[Fizzik]

I've been trying to figure out the legality of binary triggers in Delaware since I moved here last year. It's been on my mind a lot lately, especially since I've been hearing mixed opinions from folks at the range. Some say they're perfectly fine, while others claim there are specific regulations around them. As someone who's still trying to find my footing in the local laws, it'd be great to get some clarity on this. Anyone have solid info or personal experience with it? It'd really help me out.
