However, since the P365 is not an optic-ready gun, you should also find the right mounts to install the sight on the gun.

Best Sig P365 Red Dot Sights – [Editor’s Picks]

7. Sig Sauer SOR01300 Romeo Zero Reflex Sight

This ROMEOZero red dot reflex sight is specially designed to mount on the Sig Sauer P365 and P365XL models. To take your shooting experience to another level, Sig Sauer has manufactured the optic to fit onto different footprint slides like Shield RMSc footprint, J-Point footprint, and of course, ROMEOZero slide cuts.

The Spectra coat HD polymer lens works great to transfer maximum light through the glasses. In addition to that, the lens is made to be 10 times impact impact-resistant than the other slight lenses.

This optic comes with 8 different level illumination systems which allows you to use the sight in various light environments. You don’t have to manually turn on/off the illumination system.

Since the company has included a Motion Activated Illumination System in the sight, it automatically activates the illumination by sensing the motion of the gun and likewise switches it off when the gun remains idle.

Moreover, the CR1632 battery of the optic can support you for a long time. You will also like the way the stippling pattern on the housing of the optic matches with the P365 and P365XL grip patterns. This provides an integrated look to the gun. So, you can keep the sight in your option as it has direct compatibility with your P365.

Can you directly install the optic on the Sig P365?

If you have a Sig P365XL gun, you can directly install the optic. But in the case of P365, first, you will be required to mill the gun and then you can install the optic.

Does it only work with Sig P365 models?

The sight can be used to mount on any firearm that is milled for red dot optics. However, before installing the optic, ensure that your gun comes with one of the footprints as mentioned in the product description.

How much torque should you use on the screws?

You should not use more than 9Ibs to torque the screws. If you can use your hand to bolt down the screws. So, avoid over-tightening and also make sure it keeps the battery in the right place.

6. Swampfox Sentinel Micro Reflex Red Dot

What we like about the optic is how thoughtfully the quality has been ensured. To make the sight lens shockproof and durable, Swampfox has used polymer in the lens. They have also applied multi-coatings on the glasses to transfer the highest amount of light through them.

Additionally, the body is constructed with high-quality material like 7075-T6 aluminum to make sure it withstands all sorts of environmental and weather conditions. Another highlighted feature of this optic is the brightness setting. It comes with a dual brightness setting system such as Sentinel-M (manual) and Sentinel-A (automatic).

The Sentinel-M (manual) has 10 different brightness levels to manually control the brightness. It also includes Shake ‘N Wake technology to preserve the battery life when the sight motion is inactive. But as soon as it senses the motion of the optic, it resumes its previous brightness level.

On the other hand, with the help of a photosensitive sensor, the Sentinel-A (automatic) system adjusts the brightness level according to the light conditions. Since it is automatic and doesn’t include Shake ‘N Wake technology, it never sleeps and doesn’t even accidentally shut off.

However, as the Sig P365 doesn’t have an optic-ready slide, you need to find the right mount to install this sight on the gun. On the whole, if you’re looking for a durable sight that comes with a flexible brightness system, this optic is for you.

Where is the battery placed?

The battery is placed underneath the Sentinel-A setting. So, if you want to replace the battery, you have to detach the optic and then re-install the new battery.

Does it work in the night environment?

Since the optic comes with 10 levels of manual brightness settings, you can easily adjust the light intensity to work it in night environments. Besides, the auto brightness system also controls the brightness to give you a clear aim on the target.

Is it a duty-grade optic?

The optic is made with high-quality material so that it can withstand heavy impacts and rough situations. It also has a flexible brightness system to allow you to have better brightness control of the sight. Hence, you can call it a duty-grade optic as it performs equally well as these types of optics.
