I have an obsidian 45 it's a great suppressor. I was wanting the radiant but I have all dead air muzzle devices so for now I'll hold off on getting one it does look like a great suppressor though. I think you'll be happy with it.
I've got some Rugged products and I'm happy with them. They probably make some of my favorite pistol silencers and they are one of the companies I personally would buy from with confidence in them. Their customer service seems to be top notch also.
