What's your story about hearing loss from shooting guns? Does a single shot from a 45 take out some of your unprotected hearing? I use an ear protector at a shooting range but when a home defense situation comes up there will not be time to put on ear protection. Should a smaller caliber pistol be considered to preserve your ears but also your life when encountering a home defense situation? Tell me what you know, thanks. How do cops and military people deal with this?
