Hi,
I use a 6P, in an uncle mike's nylon carrier on duty, and a kydex horizontal carrier bought from Armor of NH(Ayoob's company) off duty. On duty I also have a Streamlight SL20 in a flashlight ring on my belt.
TxShooter, I had the rechargeable setup, the 6R, and do not recommend it. It lowers the output of the light. A sililar size would be the 8X, which is much better, IMO.
