Yeah. I've checked them all. Clyde at Coastal in Brunswick GA is a great guy. Got a sub gun suppressor from him. His is a mono core. Unfortunately only for Ruger. SRT is real nice they do Ruger and a Buckmark. I want to do a Buckmark. Ruger is to finicky to put back together . Thanks guysSpikey not what you're looking for exactly but have you checked these places out mentioned above?
