Like Thinhorn says, most people use the wait times and cost to avoid using a suppressor. Most of these people own a handful of weapons as well, or more.
I think there should be more opportunities available for people to try out suppressor to see the benefits for themselves.
If they did, selling off a rifle or three and using the funds to buy a suppressor would make more sense to them. The 1:20 hunters using them seems far too optimistic to me. I’ve ran into maybe 2 other hunters using one, ever.
The wait is inconsequential. I’ve heard friends complain about the wait for multiple years, but if they’d just purchase one, they’d have already been using it.
