I'm casually looking for a flashlight that will mount easily on a Picatinny rail. Most lights I've seen are sold seperate from their mounts, so I can get almost any light given the right mount. Suggestions? I'd prefer the mount to keep the light high on the frame, and apart from that my main considerations are value (lumens/life to cost) and color (black mount and light). This'll be mounted on a stainless Ruger P95PR.
