I've never had the chance to use any CT lasers. Although they do look like they are really good devices.
I really need a good tac-light because I dont like using the flashlight when something goes bump in the night, I like to have one hand free if I have to.
I have a dependible red laser but ever since I used a green one I've never really wanted another red laser. I've heard rumor that CT is working on green lasers, now that's something I'd be interested in looking at.
