Ensure the red dot sight is compatible with the SIG P320’s optics-ready slide. Some P320 models come with an integrated mounting system while others may need an adapter plate for mounting optics.

Footprint

The SIG P320 uses a unique footprint for optics, so make sure the red dot matches the slide’s footprint or comes with an adapter.

Size & Weight

The best red dot sight for Sig p320 is compact and lightweight.

A compact red dot sight will keep the overall profile of your P320 sleek, ensuring comfort and easy concealability if needed. Lighter optics are also generally more comfortable for carry and use.

Regarding construction materials, opt for a durable material, like aircraft-grade aluminum, which can withstand drops, bumps, and rough handling.

Long Battery Life

Many modern red dots offer long battery life, with some lasting thousands of hours on lower settings. Besides battery life, look for a sight with a battery that’s easily replaceable and can last a long time without needing a change. For easy battery change, get a model with either side or top loading battery compartment.

Price Range

The price of the best red dot sight for Sig P320 varies from one model to the other. Higher-end options tend to have better build quality, longer battery life, and more advanced features, but come at a higher price point.
