When I open my preorder, it'll be announced here and on my site. Unfortunately I have to wait and see how the first test shots go with my new mould. If things work out well, I'll have a good idea on when my grenades would be available. If not, I don't want to open preorder as I wouldn't have a firm idea of when I'd be able to deliver.
Thanks for your enthusiasm.
