Griffin Armament announced their new product, the CAM-LOK pistol for pistol silencers. “Covert Application Mounting – Locking” is a quick attach/detach system for pistol silencers.
They are selling the adaptors and pistons here:
I like the idea of this, but having to torque on the adapter on each pistol means you have to spend $60 for each gun you want to use it on, and you need tools to full strip most pistols for cleaning after this has been installed. But if you quickly want to attach and detach your can to move it between multiple pistol, this seems like a nice option.
