Alrighty guys wading into the deep end of the pool now. I've been researching blank firing grenades and their legality. I do understand that many fields wouldn't allow them for insurance purposes etc. And honestly that's not the side I'm interested in since I'm not playing at other people's fields and if I were and they didn't allow them that's perfectly fine. From what I've found, it seems they are pretty dang safe and used pretty commonly overseas, so I'd rather not go off track there either.
What I'd like to focus on is purely legality, and more directly legality in Michigan. From what I've been reading I've found various guys talking about the legality of them according to the ATF that they are a firearm. But that seems to hinge on being able to fire a live round. The grenades I've been looking into are primer only grenades, so there isn't a way to fire a live round, there isn't a spot to chamber a live round.
So I'm hoping someone out there has researched this further than I have thus far, because at the end of the day whether or not they are legal is just the first hurdle but it's also a very important one. So info regarding legality specifically is what I'm on the hunt for. Whether or not it's actually an ATF issue, or if it's someone reading the law incorrectly. Also whether you know of any particular Michigan State laws that would have an effect as well. I do plan to do additional checking into it with some local LEO's etc, but I'm hoping someone here has dug into it deeply enough to save me some time in my search.
Thanks!
