We chose the SRO because it provides a large field of view for improved dot tracking performance. When mounted on the Beretta M9A4, the sight picture is super fast thanks to the 1911 style grip angle.

Not Lose The Dot -  The ability to keep the dot in sight even when drawing the pistol with a full arm extension, even if the dot is slightly off center.

Automatic Brightness - The ambient light mode automatically adjusts the reticle brightness to match the lighting conditions, whether it's sunny or cloudy.

Read Trijicon SRO Detailed Review

Trijicon RMR Type 2 is the best choice for Beretta M9A4 and other pistol variants because it is the original combat-proven red dot optic that other optics want to model. The RMR Type 2 model has a tighter battery compartment to keep the electrical contact tight and prevent the dot from turning off during recoil.

Super Rugged Frame Body - The indestructible 7075 T6 forged aluminum body of the Super Rugged Frame Body can survive drops, slams, shear and other field abuse.

Automatic Mode - Lock the reticle brightness for conceal carry without accidental adjustment under garment 

Night Vision Capable - Experience enhanced night vision capabilities with the two NV mode options when using NVG (Night Vision Goggles) with this device.

Long Battery Life - Replace the battery every year to ensure a long battery life of up to 4 years.

Various Dot Sizes - 6.5 MOA is highly recommended for pistol use

The DeltaPoint Pro is Leupold's top notch micro red dot sight, which has been on the market for a long time for pistol and rifle applications. It offers similar FOV size as the Trijicon SRO, but in a rectangular shape.

Larger Window Like SRO - With a larger window like SRO but with an rectangular FOV shape, the first handgun optic in the market offers faster target acquisition speed.

Extra Housing Protection - An extra housing protection in the form of lens hood is added to protect the main optic glass frame from direct impact and increase the durability

Easier Battery Access - Load/Replace battery right from the top like Vortex Venom and Trijicon SRO! 

6 MOA - Gun enthusiasts will appreciate the availability of a 6 MOA dot size for pistol applications. The 6 MOA dot size works better for shooters with astigmatism.

Swampfox Liberty - Unique FOV Design

No products found.

We chose the Swampfox Liberty for its upward funnel design of the FOV, which increases FOV while still maintaining the same RMR mounting base to fit on any RMR slide cuts and optic plates. It also has a similar upward funnel design as the trying to mimick the Trijicon SRO.

Track The Dot Better - That slightly wider 1X27mm FOV helps 3 MOA dot tracking within the window.

Skeletonized Body - Reduce weight with the Skeletonized Body and fit it into most optic-ready holsters, including the ALS series duty holsters.

Shake Awake - Activate the optic only when in motion with the Shake Awake feature, which uses the same motion sensor technology as the Holosun 507C (even with just a small tap)

Top Loading Battery - Same user friendly design as the Trijicon SRO
