In most writings on self-defense and tactical firearm use, hearing protection rarely gets the ink space it deserves. The links in this post are to articles that offer opinions concerning information and considerations for recreational and non-recreational firearm usage, from a hearing health point of view. The author’s position, in the article Gun “Silencers” Don’t Make Them Anywhere Near Silent, is that suppressors do not work the way they should. His argument may be largely correct; however, if you devote the time to correctly setting up your suppressed defensive firearm, many of the author’s stated negatives may be avoided. If one uses a pistol with sufficient barrel length, a good suppressor, and a sub-sonic round, sound may be relegated to the less than harmful realm, even indoors. Personally, I use a generation three (not four) Glock 17, Silencerco’s Osprey suppressor, and the Remington 9mm 147 grain High Terminal Performance Sub-Sonic -- a very good dedicated suppressor round. Other ingredients are a KKM threaded barrel and, of course, our Advantage Tactical Firefly Sight. Outdoors, slide movement is all you hear on the Glock 17, while indoors you might hear a manageable pop.
