Thanks Norm...should've done that in the first place.
I have one of Dave's SST drop-ins....I didn't realize he was doing something that would fit the M3...I'll give him a shout.
If a fellow had a stock SF M3 combat light and wanted it modded to produce 1000 lumens, what would it take and who could do it if it's even possible? I know I could go with a T40CS or Cat V3 or M3x, but I like the M3 form factor.
