My house is painted bright high gloss "pure white" inside, it's so bright the whole house can be lit with 7 watts, and light bulbs are almost too bright. I've had people come in from outside and complain it's to bright inside.
I show just about everyone entering my house how a light switch works and advise if they don't want the light to come on to keep fingers and objects away from the switch.

As long as your Gun is holstered trigger covered AND even WHEN NOT HOLSTERED, if you keep fingers and other objects away from the switch, no light should come out of the end of it. Holster carefully (pay attention to what you're doing) being sure no shirt tail , holster strap etc gets near the switch, don't put the finger (boogar hook off the bang switch) anywhere inside the trigger guard until "ON target-aimed at what you want to hit" and should be fine.

When cleaning the Glock, remember remove magazine, then unchamber round (removing mag doesn't unload a semiauto) triple check that chamber is unloaded before pulling trigger to remove slide. (Don't remove chambered round then magazine, because you'll have chambered a new round when removing the chambered round if mag is left in at that time... always remove mag then unchamber then triple check.

I've had Glocks since about 1990, none have "gone off by themselves" yet. I carry ready to fire, always in a holster, with finger discipline..
