Reliable and holds zero after repeated use - ADE Advanced Optics Ultra Compact Pistol Green Laser Gun Sight

After mounting and zeroing this laser, I made a point to check it frequently during my first few sessions because I’ve had issues with others drifting, but this one stayed consistent the entire time, and that reliability makes a big difference because it gives you confidence that it will perform the same way each time you use it, and combined with the easy installation and compact design, it’s been a solid addition overall.
