Best Red Dot For Sig P365

Last but not least, the Zero from Sig themselves. The Zero is part of the famous Romeo lineup that is known to be the best value red dot optics in the market. The Zero however is not as great as the Romeo 5.

It falls short in some aspects but still provides a banger value. It’s one of the cheapest red dots in the market and there are reasons for that. Sig went with a polymer structure and a polymer lens as well.

To make sure the lenses don’t get scratched, Sig coated them to make them more durable and vivid. In day to day usage, you might mistake it for a glass lens. Yes, it’s good. The textured exterior of the optic provides a visual value and it’s quite rugged as well.

How To Choose The Best Red Dot For Sig P365?

Now that you are aware of all the good red dot P365/P365XL can handle, how about you choose one already? How do you choose, you ask. Well, let me answer my thought process while choosing a brand new optic.

Durability

The first thing that comes to mind is durability. You already know 9mm is not a forgiving caliber. The recoil can hit pretty hard and break poorly made optics on the spot. That’s why, going for an optic that has a durable construction is a must. Even polymer housing can be durable if made right. The Sig Sauer Romeo Zero is a proof of a good polymer optic.

Lens Quality

You cannot skimp out on that. A coated lens will always outperform a non-coated one. And if the lens is made out of polymer, then it has to be coated. Otherwise, it won’t be as durable as glass lenses let alone have the same clarity. As long as the lens performs the way they intended to, you should be fine. But don’t go for optics that don’t disclose lens performance.

Reticle

The red dot reticles on these sights are available in different sizes. Some even have a ring around the red dot on the center. That’s why you need to think real hard before committing behind one. Whether you want a small reticle or a huge one or one with a ring, that’s up to you totally. No one should dictate your choice of reticle. You will look through it the whole time. So, choose one that you are comfortable with.

Budget

Last but not least, the budget. The budget always keeps our spending at the bay. If you want to spend more, then by all means go for more. But if you don’t want to, then make sure to make a budget that you want to work around with. If you know that, then your choices of optics will narrow down a lot. Thus, making the decision a bit easier.

Conclusion

Would you look at that, at the end already. Hopefully, you have found this guide useful and now know a bit more about the red dots that support Sig P365. And I tried my best to help you choose the right one as well.

Don’t be frightened to explore something different. Who knows you might find the best optic for you right here. So, go ahead and choose whichever ticks most of your needs. Happy shooting.

With that said, that’s all for now. I hope to see you again sometime soon. Till then, take care and stay safe.
