The manufacturer only lists compatibility of the LaserMax Guide Rod Laser Sight for Glock 22 models as being compatible with Gen 1-3. Lasermax then has a specific model of the LaserMax Guide Rod Laser Sight for Glock 22 Gen 4 models but they do not have a compatible model for Gen5 Glock 22 models. I recommend contacting LaserMax in regards to compatibility of the LaserMax Guide Rod Laser Sight for Glocks with a Gen 5 Glock 22.
