I've had a CCW for about 10 years or so now. I carry most of the time, other when I'm at work.
There has been very few instances of CCW holders using their gun in situatiuons that don't warrant it. It's not just enough to do the paperwork, take the (required) coursework and buy a gun. The decision to carry should be taken very seriously.
Even in clearcut cases of self defense (I've been in one...gun wasn't used, but I had it ready), if you use that weapon your life is going to be interesting until things are cleared up.
In PA, one must run or try to evade use of the gun as much as humanly possible. You've got to try to retreat (except in your home). If you pull it out, you'd better be ready to use it! And, there's no such thing as "shoot to wound".
If some thug wants my money..no problem...he might get $40 or $50. If it goes beyond that, I'm going to defend myself. But I know...if I use a weapon in self defense, I'm likely going to be charged with something...up to and including murder. My life will change dramatically..at least for a time...but I will still have my life!
I always recomend citizens get their permit...if they are willing to put the time and energy in to learning how to use that gun.
"And I might be a bit uneasy sitting in a bar if the guy next to me slapping down beers was carrying."
By the way, most states prohibit carrying in a place that sells alcohol for consumption on the premises. And, in PA, CCW means concealed. You do not want to be "flashing" that gun... good way to lose your permit.
BTW, I don't strap on a Glock when operating the tractor, but I do have my .38 in my pocket with 3 rounds of snake shot and 2 rounds of hardball.
