So from the title I have just that. I upgraded my 6p Led body from the regular standard R2 that comes with it. The replacement is about 6 times brighter than the R2. My question is, are there any other drop ins more powerful? Also, I am trying to find another surefire type flashlight that will fit my "V70" hard Poly-fiber holster. I wouldn't mind a larger body, but I need something that I can buy a holster for and use on duty. Please help. Thanks
