Anyone rocking either of these products? I've read some less than endearing stuff on the Streamlight TL Racker, but it still seems pretty decent for a C- note. Also looking at a GG&G light mount for my 930 - any feedback on those? Also thought about putting the rail section on the right side of the Nordic mag clamp, but I don't really want a tape switch light. Other thoughts for adding a light to the 930?
