I carried it for a while before I swapped it for my EDC 2AA.
I did not carry it on duty, however, but know a coworker who does, he clips it inside his non-pistol side pocket using the clip provided.
This is great timing! I have had a Streamlight Polytac for quite a while and while it's OK for general use, it's relatively low lumens and the 123 battery thing has me looking hard at the rechargeable Pro-Tac. vdm, what's your take on that one?
