Although it's feasible to install the optic on a handgun without the assistance of a gunsmith, we highly recommend seeking the expertise of a professional for the installation process. It's essential to note that unprofessional installations, such as improper torque application, can lead to issues like loose screws, an inability to hold zero, damage to the firearm or optic, and even pose a risk of personal injury.
If you're not seeing a perfect round dot but instead observe a splashed dot, half-moon shape, multi-dot, or starburst, there's a high probability (99%) that you might have astigmatism without being aware of it. What you perceive is likely a small reflection of the LED light on the lens. A quick and simple way to confirm this is by using your cellphone to take a photo of the dot. If the photo shows a circular dot, you've essentially diagnosed yourself with astigmatism.
