Dude, you've received more advice than I did when starting my LEO career in 1986. I got a gun, a badge, a set of car keys, and "Hey, Let's be careful out there . . . " Relax, learn how your pistol works, don't be afraid of it, and find a comfortable way to carry it. I hate when people start preaching "Oooohhhhh, you can't assert yourself or express your opinion, because now that you're carrying a pistol, you're gonna end the argument by taking a shot at them." Those arguments are akin to the blood in the street proclamations inherent in the passage of CCW legislation to begin with. If the only tool you have is a hammer, everything looks like a nail. I'm guessing at this stage in your life you've got a lot more tools. Trust yourself. Problem solved . . .
