Better after this adjustment - LaserMax Guide Rod Laser Sight for Glocks

Laser was very easy to install in my 43x. Verified laser with bore laser and at 25’ it was dead on. Only problem out of the box was laser would turn itself off/on while shooting, thought it was my hand position but discovered it was the spring tension on the included slide lock bar used to turn on the laser. The weak spring tension allows the lock bar to “walk” back and forth, turning the laser off and on. The included spring has slightly more tension than the stock spring, but after a couple of minor pulls on the spring ends, the slide lock bar now stays in place with a more positive feel when turning the laser on/off. So stretch the spring and enjoy the best laser for a small concealed handgun you can buy!
