Unless I'm alone, others around usually don't have them so hearing protection are still required.
As much as I'm tempted to research suppressor options, I keep coming back to that sticking point. They mostly just make sense [to me] for emergency self defense type stuff. Shooting with friends or at the range, which is all I've ever done to-date, makes cans a rather pointless luxury.
I've often wondered what the "real" cost of suppressors is, but always got sidetracked and never looked it up... The typical $800-900 cost seems way out of line with the materials and manufacturing that goes into them. Seeing the two comments earlier in this thread about the non-legislated cost being closer to $100 supports what I figured.
