When we take the horses out for a ride in local state forest, the trailhead is next to a shooting range. Seems at 9am the shooting starts and it can be a lot and the trail runs fairly close to the range, borders their property. Horses aren't bothered, but I guess if all of them had suppressors it wouldn't be as loud, so that may be a benefit. And other people in a more urban area that's near shooting or hunting wouldn't be annoyed by loud gunshots. When I shoot at game it's usually dead, loud noise or not, so I don't care if they are scared by the bang. And I target shoot somewhere remote on my own so nobody is around. No suppressor for me.
