Choose a red dot sight with a long battery life, especially if it’s meant for everyday carry (EDC). Some models offer battery life measured in thousands of hours, which means less frequent battery changes.
Dot Size and Reticle Options
Red dots typically come in sizes ranging from 1 MOA to 8 MOA. A 6 MOA dot is a good balance for rapid target acquisition without being too large for accuracy. For concealed carry, you may prefer a smaller dot size of 2 MOA or 3 MOA for precision at longer distances.
With reticle options, some sights offer different reticle styles like simple dots, circle-dot combinations, or even different color options. Choose one that feels intuitive and easy to acquire.

Ease of Adjustment
Ensure the sight allows for easy and precise windage and elevation adjustments without tools, so you can quickly zero it in and make adjustments on the fly.
Brightness Control
Next, consider brightness control. The best red dot for Sig P365X features intuitive brightness control, whether through buttons or automatic sensors for quick adaptation in different lighting conditions.
Price Range
Red dot sights vary widely in price. While premium options can offer better performance, the price may not always justify the features for a carry pistol. For the Sig P365X, mid-range models are often the best choice, balancing quality, reliability, and cost.
Final Words
Hopefully, this buying guide has been insightful and of immense help to you. When making a selection, consider your specific needs, such as concealability, intended use, and budget, to choose right. Whatever you have in mind, there is a red dot sight out there waiting for you.
