I have a Surefire 9p with a Q5 BOG dropin using Surefire primaries and am pretty happy with it. What combination of batteries and dropin would give me the most light output though? I am looking for more flood than throw. I have a WF 139 charger and have been using LiIon for a few months now. Can I even fit LiIons in my 9p? Thanks for the help guys. Mods feel free to move this if I have posted it in the wrong forum.
