  1. Size and weight

Size plays an important role when it comes to choosing a red dot sight. While all red dot sights essentially perform similar tasks, the size of your firearm will greatly determine which optic sight is right for you. A smaller pistol will greatly benefit from a smaller red dot sight.

Also, look for a lightweight optic that’s easy to handle and easy to transport as well.

2. Battery life

Another important factor to consider is the battery in regard to the battery life and ease of access. It’s important that you choose an optic whose batteries are easily available for replacement. Moreover, you’ll need an optic with a long-lasting battery. The battery should meet the needs of how long you intend to train or utilize the firearm for real action.
