I have a rough time carrying lights loose in pants pockets -- got too much cellphones, pocket computer, keys, etc. there already.
My current loadout (kinda heavy, since depending which shift they put me on I am either walking/cycling to work at 0dark30 in the morning or home the next morning) is:
- Modded fauxton on keys
- Microstream AAA pocket clipped in pocket
- hotrod 14670 minimag in a belt holster
- WF-008 recoil thrower in another holster
- Download's MC-E EDC (one of my current bike headlights) in pants pocket (Yeah, I said I don't like this. Still looking for a deep-carry clip for it, but light is nice enough I have to have it on me.)
And these, all in my leather jacket:
- x2000 (zooming aspheric) 3xAAA-on-18650 (other headlight)
- First Alert 10-color (RGB flood) 3xAAA-on-18650 (taillight, set to red blinking)
- Usually one to three other smallish (18650/3xAAA/2xAA) lights
- One big gun -- 2C to 3D size, Mag or Brinkmann, hotwire or LED
As for the coin pocket -- it's great for spare 14670s and 18650s. If I wasn't carrying bike lighting on my person, I probably wouldn't need so many spares, and that pocket would work great for flashlights, especially tiny stuff like your Mini123. But mine is pretty full, and most of my EDC lights are a little big for it.
For a while, I EDCed an EZ-AA with deep-carry clip, clipped into my shirt collar. But it got to be too much hassle putting it on every morning, and I already had the streamlight (for low-mode = up-close work) and minimag (high = everything else), so the EZ-AA was kinda redundant. After I lost my Akoray, it didn't share batteries with anything else, so rather than pack a spare 14500, it just wasn't worth packing.
So far, I've received a number of comments from coworkers about my flashlights from my using them, but no comments at all about the belt holsters, so I don't know how much to believe those who say they're especially dorky looking. (Did get a comment when I was rushing in one morning and forgot I had a 4D MagP7 swinging on my hip, but that's not EDC...)
