I had a veridan reactor green laser on a khar cw9. Magnets in the holster deactivated the laser when holstered. The laser activated when drawn from the holster . If you practice regularly be prepared to buy a lot of batteries. If the gun sat inactive for a month the batteries would be weak or dead. After a year I gave up and moved on to a sig p365 with night sights. I’ve been happy with that set up ever since.
