I've got a mod.2 9mm sub compact and I really want to add a weapon light (preferably with a laser) to it. I was planning on getting a streamlight tlr4g but when I was reading the specs I noticed the length was 2.73in which would mean it would stick out wwaaayyy past the end of the barrel and I'd prefer something a little shorter. Does anyone have any recommendations for a light/laser combo that isn't quite so long?

Light and laser?  Get the Viridian C5L.  

I really like that, how stiff is the button?
