If you live in a silencer-friendly state/country and you don’t have a can on your home defence gun, that should be your next purchase. Think about the standard home defence scenario. You’re in an enclosed space, facing an unknown number of a**holes, and all you have on your side is stealth and surprise. Firing a gun in that situation immediately makes the situation worse. Now you’re now deaf. Not permanently, but enough that it’s painful and disorienting. Where are the bad guys? You need to hear if they are still moving, where they are, etc. Movie’s aren’t real.
