I am now using the Fenix T1 when I walk the dog. It pairs nicely with my Glock.
However...and please forgive me for this heresy...as we said in the Army, "darkness is my friend". I am a low profile guy; so I use the Fenix rarely...this is the city so there is a LOT of ambient light.
(Now checking throw, spill and "usefulness" of different lights is a different matter.
)
I have used it for finding the dog when he (rarely) slips the leash and sometimes for picking up his poop. The T1 really gives too much light for this last duty.
I do see other dog walkers wearing headlights, carrying generic Evereadys, Dorcys, etc. and occasionally Surefires; they sure can be seen from a long way away.
Even walking the dog during the day, I find myself sometimes judging distances and spaces and saying "Yep, Fenix T1 would be great for that area but my E2E would be more than adequate, but the L0D-CE would not provide enough light"....just the usual musings of a flashaholic in the daytime.
