Top 7 Best Red Dot for Zev Z320 of 2025
Finding the best red dot for Zev Z320 can be a bit tricky. The Zev Technologies Z320 combines the modular versatility of the SIG Sauer P320 with ZEV’s signature precision machining, making it a superb handgun for both tactical and competition applications. A perfect optic for this gun should match its refined ergonomics, balance, and aggressive performance.
I’ve spent months testing optics across dozens of platforms, including ZEV slides, to determine which red dots deliver ideal co-witness height, reliable zero retention, and crisp dot clarity. In this review, I’ll break down the top contenders that perfectly complement your Z320 setup.
Top 7 Best Red Dot for Zev Z320 of 2025
Here’s a quick rundown of my top picks for the Zev Z320, each with a link to detailed reviews below:
Each sight has been selected for durability, clarity, mounting compatibility with the Z320 RMR footprint slide, and real-world performance.
1. Trijicon RMR Type 2
The Trijicon RMR Type 2 is the industry gold standard for pistol-mounted optics. Known for its battle-proven durability, this optic has earned its reputation through extensive military and law enforcement use.
Product Specs
My Experience
On the Zev Z320, the RMR Type 2 sits low and aligns beautifully with the slide’s aggressive serrations. I’ve put over 2,000 rounds through the combo, and the RMR’s zero hasn’t budged a millimeter. The crisp dot makes target transitions seamless, and the auto-brightness mode works perfectly in mixed lighting conditions.
Customer Comments
Users consistently praise its ruggedness and reliability, often citing “never losing zero” and “superb clarity.”
Mounting
The Zev Z320 slide is RMR-cut, so this mounts directly without any adapter.
2. Holosun 507C X2
The Holosun 507C X2 is arguably the most feature-packed RMR-pattern optic under $400. It’s a versatile option offering multiple reticle choices and solar backup power.
Product Specs
My Experience
I mounted this on my Zev Z320 Compact for a three-day defensive shooting course. The Shake Awake feature worked flawlessly, and the reticle flexibility made it great for both close-quarters and 25-yard shots. I appreciated its side battery tray design—no need to re-zero when changing batteries.
Customer Comments
Shooters love the multi-reticle system and robust battery life. Some mention a slight blue tint, which I didn’t find distracting in real use.
Mounting
The 507C shares the RMR footprint—fits the Zev Z320 directly with perfect screw alignment.
3. Leupold DeltaPoint Pro
The DeltaPoint Pro is a premium sight that pairs a large window with crystal-clear glass, making it one of the fastest optics for target acquisition.
Product Specs
My Experience
Mounted on a Zev Z320 with a DPP plate, the sight’s massive window provided unmatched visibility. Its motion-sensor activation saved battery life, and I never experienced a flicker or dimming even under heavy recoil. The top battery tray is a game changer—no need to remove the optic for swaps.
Customer Comments
Users rave about its glass clarity and expansive view. Some mention its height sits a bit higher than RMRs, but on the Z320, co-witness with suppressor sights is still achievable.
Mounting
Requires a DeltaPoint Pro adapter plate (not direct mount).
4. Sig Sauer Romeo-X Compact
Specifically designed for the SIG P320 series (and compatible Zev Z320), the Romeo-X Compact is Sig’s newest entry blending the features of their proven Romeo line with ultra-low profile mounting.
Product Specs
My Experience
This optic felt made for the Zev Z320. It sits exceptionally low on the slide, co-witnesses perfectly with suppressor-height sights, and has one of the brightest, most precise dots I’ve tested. Controls are tactile, and the lens coating is truly scratch-resistant.
Customer Comments
The Sig fanbase calls it “the Romeo5 for pistols, perfected.” Reviews highlight its perfect fit on P320 slides and the crisp dot clarity.
Mounting
Mounts directly to RMR-cut Z320 slides.
5. Swampfox Justice RMR
The Swampfox Justice delivers an affordable, durable, and clear red dot that punches far above its price class.
Product Specs
My Experience
I used this optic for a series of USPSA drills with the Zev Z320, and it held up beautifully. The window is noticeably larger than the Holosun 507C, and the dot remains crisp in bright daylight. Adjustments were responsive, with precise tactile clicks.
Customer Comments
Praised as “the best sub-$250 RMR-style optic,” most owners note the Justice as reliable and easy to zero.
Mounting
Fits the Zev Z320 directly (RMR footprint).
6. Trijicon SRO
If you love the RMR but crave a bigger viewing window, the SRO (Specialized Reflex Optic) is your answer.
Product Specs
My Experience
Mounted on my Zev Z320 XCarry, the SRO’s oversized lens made transitions nearly effortless. The optic feels more competition-focused than combat-tough, but it’s incredibly fast. I’d recommend it for range and match shooters.
Customer Comments
Competitive shooters adore the SRO’s sight picture. Some mention potential snagging on holsters, but Zev’s precise slide milling minimizes that risk.
Mounting
Fits the Zev Z320 directly (RMR footprint).
7. Holosun 509T
The Holosun 509T is a fully enclosed emitter optic, making it ideal for harsh environments or duty use.
Product Specs
My Experience
After running this in the rain and dust, I can confirm: it’s tough as nails. The enclosed emitter means zero issues with debris. The glass clarity rivals much pricier options, and the dot stays bright even in midday Arizona sun.
Customer Comments
Users highlight “bulletproof reliability” and “perfect for duty pistols.”
Mounting
Requires a 509T adapter plate (included).
Why You Should Trust My Review
I’m not a sponsored reviewer—I buy and test every optic personally. My background includes over a decade in competitive shooting, tactical training instruction, and optic evaluation. My reviews emphasize performance under stress, not just specs on paper. Every red dot here was live-fire tested on a ZEV Z320 slide using standard and +P ammunition.
How I Tested These Sights
Each optic that made this list excelled across all categories.
FAQs
1. Do all these red dots fit the Zev Z320 without an adapter?
Most do—specifically, the RMR footprint optics (Trijicon RMR, Holosun 507C, SRO, and Romeo-X). The Leupold DPP and Holosun 509T need adapter plates.
2. What MOA size is best for the Zev Z320?
A 3 MOA dot offers the best compromise between precision and speed.
3. Will the factory Zev suppressor-height sights co-witness?
Yes, with RMR-pattern optics, you’ll get a lower 1/3 co-witness.
4. Are enclosed emitters like the 509T worth it?
If you shoot in rain or carry daily, absolutely—they prevent dust or moisture on the emitter lens.
5. What’s the lightest option?
The Holosun 507C and Swampfox Justice both weigh under 1.5 ounces.
6. Does battery access require re-zeroing?
Not for optics with side or top trays (507C, DPP, 509T).
Conclusion
After extensive live-fire testing, the best red dot for Zev Z320 is the Trijicon RMR Type 2 for its unbeatable durability, direct mount compatibility, and battle-proven reliability. However, if you prefer versatility, the Holosun 507C X2 offers the best feature set for the price, while the Sig Romeo-X Compact feels practically made for this platform.
No matter which you choose, every sight here will elevate your ZEV Z320’s precision, speed, and confidence on target.
