Any ideas anybody how this gadget works? It's simply clipped onto the accessory rail of any G17 or 19 w/o need for a threaded barrel - how can a suppressor function without actually being attached to the barrel?
You can have a suppressor that isn't even attached to the gun. People build suppressors that are permanently installed at a range. A common design is a number of tires forming a "sideways stack" where the muzzle is placed inside one end of the stack for firing.
