To me 5.11 pants tell me the guy is a shooter, a fed, a cop, or a wannabee poser.
All of which announce you probably have a gun. Which you may or may not want to announce.
For that reason, “photographer’s vests” etc are often called the “shoot me first vest” since you will appear to be the biggest threat to the shooter.
Avoiding the khaki, black and police-department blue versions helps. I've got one in blue jean denim with mostly internal pockets that's less a liability, but in Wyoming full-length sleeves are seen pretty near year-round. And flannel lined Levi/wrangler jackets are real common, even after the first snows fall. And so far, this year, the last ones haven't quite quit.
I'm more inclined to first drop the guy wearing a longer field jacket or parka, a raincoat or western duster out of season or local weather conditions. Think Doc Holliday with the sawed-off double barrel shotgun at the OK Corral at Tombstone, carried butt-in-the-armpit [*211 sling*] under a long coat.
