Lasermax lasers are made here in my hometown area. They work very well. They are extensively tested before they are sold, so you know you can depend on them. I have two installed in two of my non S&W pistols. I am very pleased with them. The best part is that since the internal laser actually replaces the guide rod, there is no adjustments to worry about. You will hit where the laser is on your target as long as you stay steady. Their service after the sale is excellent. I would not hesitate to buy one. Hope that helps.
