Top Red Dot Sights for Pistols

Red dot sights are quickly becoming more prevalent on handguns — especially for self-defense. Many popular handguns are now offered with optic-cut slides and even factory-mounted optics. 

Red dot optics provide a number of benefits over traditional iron sights. Shooters do not need to take the time to align front and rear sights to acquire an accurate sight picture. Simply present the pistol and put the dot on the target. Of course, there is a training curve when transitioning to a red dot. Once you get it down however, it becomes natural. This allows you to focus more on the threat. 

Particularly with electronics, it’s important to go with something high-quality. The shock and abuse from firing a gun can cause a lot of wear and tear if the red dot is not built properly. There are many great red dot optics on the market today, however, the choices on this list are exceptional. 

Trijicon RMR Type 2
The Trijicon RMR is one of the most popular red dot sights.

Trijicon RMR Type 2

This may just be a bit of personal bias seeping in, but when I think of quality red dot sights, my mind immediately turns to the Trijicon RMR. The “Ruggedized Miniature Reflex” has an extensive history of rugged durability in both civilian and institutional use. The Type 2 features redesigned and updated electronics which are more reliable. It is available with either a 1-, 3.25-, or 6.5 MOA dot. Many shooters prefer the 3.25 MOA dot because it’s large enough for the eye to pick up quickly and small enough for precision.

The 1X magnification optic features different brightness settings to adapt to various lighting conditions. Adjustment buttons with audible clicks allow shooters to quickly change windage and elevation settings on the fly with 1 MOA adjustments. The optic is powered by a reliable CR2032 3V Lithium battery and constructed in a rugged forged aluminum housing so you can be sure it will work when you need it.

Trijicon SRO

The Trijicon SRO (Specialized Reflex Optic), is the bigger brother to the RMR. However, instead of being optimized for hard use, it’s set up for accuracy. The wide field of view and clean, crisp dot make it easy for users to find and track the dot in both target and competitive shooting applications, helping to improve shooting accuracy and speed. With 1-, 2.5-, or 5 MOA dot options, shooters can choose the version with their preferred dot sight for their specific shooting applications. 

Like the RMR, the 1X optic is incredibly durable and built on a 7075-T6 forged aluminum housing. It’s powered by a CR2032 battery and features over 3 years of continuous use.
