Get a Surefire for a fighting tool.

Buy cheap, buy twice.

Or three times.

Surefires look pretty good on their website. I don't need anything with super high output, but I want something that is reliable, of good build quality, and will tolerate the recoil of a 12-gauge. Never been big on weapon-mounted lasers, but I like the idea of being able to positively ID a target in a dark apartment should I ever hear a bump in the night. Since I'm not stalking hidden snipers in the forest, I'm not worried about it giving away my position.
