Most of what’s being sold right now has more than “6 or 7” - which bears out what my local ranges/stores are telling me. The new high-capacity microcompacts are the current hotness far and away.
I live in a relatively homogeneous, low crime, Trump area and feel adequately armed to pump gas or go grocery shopping while carrying a J frame and a couple speed loaders.
Of course, I still carry other stuff in by backpack, readily at hand in the vehicle.
If I have to be in an iffy part of Pittsburgh, that's a different story.
