These days few men wear suits or sports jackets on a regular basis and that is why Pocket Carry has become so popular. The old Photographers vest, fanny pack, phone case on steroids, etc. is a sure give-a-way to people in the know and I would feel like a Dufuss anyway.
I do not buy into the "dress around the gun" theory! Anyone astute enough and who observes can pick the "dress around the gun guys" right out. I will not carry a gun that I need to dress different than normal or different than the weather requires. Wearing a Photographers vest in the Mall in July might not look normal - ya think?
I do pocket carry at least half the time and belt carry the other times when my attire or surroundings dictate I can without standing out like a sore thumb. When I am in the Woods or on private property where legal, concealment becomes a non-issue.
A M60 (or similar) , Colt Dick Spl. or reliable pocket pistol would seem to fit the bill for most if us. Bear Country = .357 or .44 Magnums but concealing is not an issue.
