1. SIG Romeo Zero Elite – My Top Pick

I’ve had the pleasure of testing the SIG Romeo Zero Elite red dot sight on my SIG P322, and let me tell you, it has truly impressed me. 

This sight’s key features, including its compatibility with 22LR use, the TAP system, and the glass lens, are a shooter’s dream come true. The aspherical glass lens caught my eye, eliminating any edge distortion. 

It’s not just something on paper; using it in the field made my aim crystal clear. The sight’s super lightweight design, even with the metal shroud, meant that it never felt heavy. 

I’ve tried many red dot sights, but with its robust construction and multi-reticle options, the Romeo Zero Elite felt like it was designed just for me and my SIG P322. 

Its features enhance my shooting experience like no other sight has ever done.

Flaw but not a dealbreaker

  • The brightness and reticle selection buttons can be small and tricky to operate for some users, but it doesn’t take away from the sight’s overall excellence.

2. HOLOSUN HS507K X2 – Highly Recommended

My experience with the Holosun HS507K-X2 on my SIG P322 has been nothing short of extraordinary. Designed with durability in mind, its high-grade aluminum construction can withstand significant impacts, and that’s just the beginning. 

Fast target acquisition with the red dot is easy, whether I’m shooting at bowling pins or steel plates. 

The seamless integration with the SIG P322 and the convenience of changing the battery without sight removal only adds to its appeal. 

The Holosun HS507K-X2 is versatile and efficient, and its performance under different conditions has convinced me that it’s a top option for any serious shooter.

Flaw but not a dealbreaker

  • The sight’s battery side tray screw is relatively small and may be tricky to handle, but it’s a minor concern in an otherwise outstanding design.

3. Holosun 407K X2 – Best Seller

Let’s chat about the Holosun 407K X2, a sight that’s not just popular but holds a special place in my shooting gear. Testing this on my SIG P322 was an eye-opening experience. With its 6 MOA dot, this sight is a real game-changer. 

Even in rough outdoor conditions, it proved sturdy and robust, thanks to that 7075 T6 aluminum housing. The convenience of side battery replacement made it a breeze to maintain. Its 50,000-hour battery life ensured reliability. 

It’s compact, lightweight, and worked like magic with my pistol. If you’re a fan of red or green, the reticle doesn’t disappoint in offering both. It’s easy to see why it’s a bestseller.

Flaw but not a dealbreaker

  • The sight’s finish is not upto pro standards, but the ‘pro standards’ could be subjective

4. Holosun EPS – Exceptional Value

Alright, let’s talk about the Holosun EPS Sight. I had the chance to test this baby out on my SIG P322, and I must tell you, it was an adventure! Durability? Check. 

That reinforced aluminum alloy housing took a beating like a champion. The shock absorption system had me grinning, knowing that I could trust it in high-impact situations. 

Rain, humidity, a dip in a puddle? No problem! Now, that 2 MOA dot within a 32 MOA circle is like a little magic trick for your eyes – it got me those lightning-fast target acquisitions. 

And the brightness settings have twelve levels to choose from, and all those daylight and night vision settings meant I was never left squinting. 

Windage and elevations? Oh, they were spot on, helping me nail those shots regardless of conditions. All in all, the EPS Sight was a joy to use, especially that scratch-resistant lens.

Flaw but not a dealbreaker

  • Occasional parallax issue; although rare, it can throw you off momentarily. Not a biggie, but worth keeping in mind.

5. Swampfox Sentinel – Solid Options

So, let’s dive into the Swampfox Sentinel, shall we? This little guy became my trusty sidekick on the Sig P322. Built with that 7075 T6 aluminum, it’s slim yet rugged, making it a reliable choice. 

But here’s what really caught my eye: the low-profile lens hood. 

Now that’s impressive! The Ironsides Shield? It’s like armor for your sight, ready to take a hit and keep on going. And the brightness modes – oh boy, having options for manual and auto adjustments was like having a tailor-made suit fitting for any lighting condition. 

The 3 MOA red or green dot was bright and clear, and that battery life? Two years! No fuss, no muss.

Flaw but not a dealbreaker
