For starters, I wear Carhartt Work Dungarees literally ALL the time. They have a deep, narrow tool pocket on the side of each thigh. The gear I carry is always the same and it's always in the same places:
XD45 Compact w/Lasermax internal laser & 10+1 HST+P
Comp-Tac Minotaur IWB w/full forward cant @ 4:00
Carhartt 1-1/2" heavy leather belt
13 round mag with HST+P in LH thigh pocket
serrated Spyderco Civilian clipped to rear of RF pocket (vertical)
SOG Twitch 2 clipped to top of LF pocket (nearly horizontal)
Xenon flashlight in RH thigh pocket
car keys clipped to RF belt loop and tucked into "5th" pocket
wallet in LR pocket
cell phone w/camera in LF pocket
(RR pocket is useless due to canted IWB)
I think some may not have considered how important clipping your car keys to a belt loop could be. If you end up rolling around on the ground with an attacker(s) it's pretty easy to end up with whatever was in your pockets scattered all over the place. I want retention of my .45 1st, car keys 2nd, and cell phone 3rd. They can have the rest!
