Things To Keep in Mind Before Buying

Choosing the right sight for your gun requires some experience. A lot of you guys lack that. Don’t worry, that’s where we reviewers step in. Keep a couple of things in mind and you will be golden.


We are going to pair these sights with a pistol. We can’t forget that. Pistol rail can only take so much. Don’t try to mount a full-fledged riflescope on top of it. Cause, this is not a video game. It won’t work.

Lens Quality

Most red dot sights only have one lens. If that lens is not good enough, I don’t think you should bother purchasing that optic.


Lightweight sights are kind of mandatory. Pistol is a lightweight weapon. On top of that, it’s already a bit back-heavy. If you take a heavy optic, then you will face a balancing issue. It’s better to take lightweight sight.
