The Walther light, and the LaserDevices light are the exact same thing, except the LD light isn't marked with the Walther banner, and costs $100 less.
I've looked into the LD light only, no laser, but i'm still waiting on first hand reports. http://www.laserdevices.com
I'm thinking the light only, without the add-on laser.
Anybody used one?
Unfortunately, that is the light only. the laser replaces the light head. Its an "either or" design.
When compared to an Insights M3, its huge, when compared to the Surefire weapons lights it's just very large.
But it's the only thing out there for P99's right now.
