We’ve spent the past few weeks running the HOLOSUN 407/507COMP Series 6 MOA or 2 MOA Dot & 8/20/32 Circle Reflex Sight through drills, match prepand a few “what if” range days to see if it really moves the needle for competitive pistol shooting. Built around a generous 1.1 x 0.87 inch viewing window, this open-emitter optic immediately changes the sight picture-targets feel easier to catch on the draw and transitions flow with less hunting for the dot.
What sets the 507COMP apart in practice is holosun’s Competition Reticle System: a crisp 2 MOA center dot with selectable 8, 20and 32 MOA circles that we could run solo or in combination depending on the stage and lighting. The 407COMP takes a simpler, bolder route with a 6 MOA dot that pops fast and tracks cleanly.both share a familiar RMR footprint, durable 7075-T6 aluminum housing, IP67 weather sealingand the quality-of-life features we expect at this level: manual brightness with Memory Mode, Lock Mode to prevent accidental changes, Shake Awake for instant-onand a side-loading CR1632 tray. Holosun’s Super LED promises up to 50,000 hours on setting 6, which we didn’t come close to denting, but the battery setup made top-offs painless.
In this review, we’ll break down how these optics handle speed, precision, durabilityand day-to-day usability-and whether the reticle options, big windowand power management add up to a true competitive edge.
our Hands On Overview Of The Holosun Comp Series Reflex Sight
After mounting the Comp series on a full-size slide, we immediately appreciated the large competition window (1.1″ x 0.87″)-it keeps the dot visible through recoil and during hard transitions. The Super LED is crisp and daylight-capable, while manual brightness with Memory Mode preserves our preferred setting between strings. build quality is excellent: the 7075‑T6 aluminum housing feels rock-solid without extra weight, the IP67 rating shrugs off weather, and the RMR footprint made setup straightforward on both full-size and compact pistols.
- Shake Awake brings the optic to life on the draw; it powers down when idle.
- Side-loading CR1632 battery enables swaps without disturbing zero.
- up to 50,000 hours of runtime (setting 6) for match-season staying power.
- lock Mode prevents accidental clicks; controls are competition-friendly.
- Wide FOV supports faster target acquisition and steadier dot tracking.
| Model | Reticle Style | Dot size | Circle Options | Best Fit |
|---|---|---|---|---|
| 407COMP | Single, bold | 6 MOA | – | Pure speed, low visual clutter |
| 507COMP | CRS multi-reticle | 2 MOA center | 8/20/32 MOA | Stage-tunable sight picture |
On the clock, the 6 MOA dot of the 407 variant pops instantly for fast plates and close-to-mid arrays, while the 507’s Competition reticle System (CRS) lets us tailor the sight picture-from a sharp 2 MOA center to larger 8/20/32 MOA circles that frame partials and movers. Between the side tray, battery longevityand confidence-inspiring housing, this optic feels purpose-built for dynamic shooting.

Reticle choices drive usability. The 507’s Competition Reticle System (CRS) lets us run a precise 2 MOA dot, an 8/20/32 MOA circleor combinations to tune speed versus precision. For a more streamlined feel,the 407 model uses a bold 6 MOA dot that’s fast to pick up and easy to track through recoil. The generous window helps whichever pattern we choose, making it simple to pair a fine aiming point with a big, confidence‑building reference ring when a stage demands both.
| Pattern | Best Use | Benefit |
|---|---|---|
| 6 MOA Dot | Close targets | Fast pick‑up |
| 2 MOA Dot | Precise shots | Refined hold |
| 8 MOA Circle | Tracking | Subtle guide |
| 20 MOA Circle | Mixed stages | Balance |
| 32 MOA Circle | Speed drills | Bold index |
| Dot + 32 | Speed + precision | Dual cue |

Real World Performance Tracking And Ease Of Adjustment
On the clock, tracking felt instinctive thanks to the expansive 1.1 × 0.87 in window and crisp Super LED. The 507 variant’s Competition Reticle System (CRS) let us tailor the sight picture to the stage: a fine 2 MOA dot for partialsor concentric 8/20/32 MOA circles to build a bold visual funnel that stays visible through recoil. When speed was the priority,the 407’s 6 MOA dot gave us a confident flash sight picture and quick confirmation on transitions. Across drills, the generous field of view made it easier to catch the dot after slide movementand we appreciated how the large window reduced hunting at awkward angles.
| Reticle Mode | Visual Cue | Best Use |
|---|---|---|
| 6 MOA Dot | Bold center | Blazing splits |
| 2 MOA Dot | Fine point | Precision hits |
| 8 MOA Circle | Tight ring | Close confirmation |
| 20 MOA Circle | Mid ring | Transitions |
| 32 MOA Circle | Large funnel | Tracking under recoil |
| Dot + circle | Dual cue | Mixed targets |
Adjustment in the wild was refreshingly simple. Manual brightness with Memory Mode kept our chosen level consistent from stage to stageand Lock Mode prevented accidental bumps when holstering or clearing barricades. The Shake Awake feature brought the dot up the moment we moved, while the side-loading CR1632 tray meant battery swaps without pulling the optic off the gun. Long runtimes (up to 50,000 hours at setting 6), a rugged 7075‑T6 housingand IP67 sealing supported confidence in all weatherand the RMR footprint made mounting straightforward across full-size and compact pistols.
- Memory Mode: Comes back on exactly how we left it.
- lock Mode: No more surprise clicks mid-stage.
- Side-loading CR1632: Quick changes; no unmounting.
- Shake awake: Instant-on when we move.
- RMR Footprint: Broad, hassle-free compatibility.
Who Will Love It And How We Recommend Setting It Up
Who will love it? Competitive pistol shooters who value speed, a generous 1.1 x 0.87 in viewing windowand flexible reticle options will feel right at home. The CRS multi-reticle shines for stage-specific tailoring-run a crisp 2 MOA center dot alone for tight groups or add 8/20/32 MOA circles to burn down transitions. If you prefer a bold, uncluttered aiming point, the 6 MOA dot option keeps things simple and fast. We also see range instructors and high-volume shooters appreciating the practical touches: up to 50,000 hours on super LED (setting 6), a CR1632 side-loading tray, Shake Awake for instant-on, Lock Mode to avoid accidental bumpsand a rugged 7075‑T6 aluminum build with IP67 waterproofing. The RMR footprint means broad compatibility across full-size and compact pistols, making it an easy upgrade path for most setups.
| Scenario | Reticle Choice | Zero | Quick Tip |
|---|---|---|---|
| Fast, up-close arrays | 6 MOA dot or 2 MOA + 32 MOA | 15 yd | Favor speed over precision |
| Mixed distance stages | 2 MOA + 8/20 MOA | 25 yd | Use circle to “drive” the dot |
| Precision plates | 2 MOA dot only | 25 yd | Dim brightness slightly for finer aim |
How we recommend setting it up starts with the mount: verify your RMR-cut slide or plate, apply blue threadlockerand follow the manufacturer’s torque spec. Zero at 15 yards for speed-focused matches or 25 yards for a balanced do-it-all setup, than confirm at intermediate distances. Dial brightness manually for conditions, enable Memory Mode so your setting returns automaticallyand use Lock Mode before the beep to keep controls locked during movement. The large window rewards a true target focus-let the dot float while the circle (if enabled) guides your transitions. keep a fresh CR1632 handyand take advantage of Shake Awake to preserve that marathon battery life.
- Choose your reticle: 6 MOA for simple speed; 2 MOA for precision; add 8/20/32 MOA circles when you want faster indexing.
- Brightness baseline: start near setting 6 in daylight (great for longevity), bump as needed under harsh sun.
- Iron co-witness: suppressor-height sights are a smart backup on competition slides.
- Stage-proof the setup: lock controls, witness-mark screwsand recheck zero after major round counts or plate changes.

Q&A
Q: What’s the big idea behind the 407/507COMP series?
A: Speed you can see. Both models center on a large 1.1 x 0.87 inch window that lets us track the dot and the target at the same time, which helps with faster transitions and confident sight confirmation under pressure.
Q: How do the 407COMP and 507COMP differ?
A: The 407COMP is the simpler, go-fast option with a bold 6 MOA dot. The 507COMP adds Holosun’s Competition Reticle System (CRS), giving us a 2 MOA center dot plus 8, 20and 32 MOA circle options we can run solo or in combination.
Q: who should choose the 6 MOA dot versus the CRS multi-reticle?
A: We’d pick the 6 MOA on the 407COMP if we want fast, prominent indexing and minimal decision-making. We’d choose the 507COMP’s CRS when a match or training block benefits from tailoring the reticle-small dot for precision, big circle(s) for rapid acquisition and tracking.
Q: Do the CRS reticles share the same zero?
A: they’re designed to be used interchangeably. As with any optic, we re-confirm zero after major changes to be safe.
Q: Does the larger window actually make us faster?
A: In practical terms, the big window makes dot re-acquisition more forgiving and keeps more of the stage visible around the reticle. That visual freedom is where the speed lives.
Q: How’s battery life and replacement?
A: Up to 50,000 hours on setting 6 from a CR1632and the side-loading tray means we don’t remove the optic to swap batteries.
Q: What do Shake Awake and Lock Mode do for us?
A: Shake Awake turns the sight on with motion and conserves power when idle.lock Mode prevents accidental brightness or reticle changes once we’ve dialed our settings, which is great for match day.
Q: Are the brightness controls competition-friendly?
A: Yes. Manual brightness with Memory Mode keeps our last-used setting,so we don’t get surprises between stages or after a power save.Q: Is it durable enough for hard use and bad weather?
A: The 7075-T6 aluminum housing and IP67 rating give us confidence in rough conditions. It’s built to be light, rigidand sealed.
Q: Will it fit our pistol?
A: It uses the RMR footprint,which covers a wide range of full-size and compact pistols. Fit still depends on slide milling or adapter plates, so we verify compatibility before mounting.
Q: Any notes on co-witnessing with irons?
A: It depends on our slide cut and sight heights. With the RMR footprint, co-witness is often achievable using the right plate or suppressor-height irons.
Q: Is the 507COMP better for shooters with astigmatism?
A: Results vary by eye. some of us find larger circles easier to perceive cleanly at moderate brightness, while others prefer the 6 MOA dot. We keep brightness as low as practical for the crispest view.
Q: Is this optic strictly for competition?
A: It’s optimized for competition-big window, fast controls-but it can pull range or duty double-duty. For concealed carry, we weigh the larger window against our concealment needs.
Q: Does switching reticles or brightness risk bumping settings mid-stage?
A: That’s exactly what Lock Mode is meant to prevent. We set it, lock itand run.
Q: Any drawbacks we noticed?
A: The trade for that expansive window is a larger on-slide profile than micro-sized dots. if maximum concealment or ultra-minimal mass is the goal, that’s worth considering.
Q: Bottom line-who wins with the 407/507COMP?
A: Shooters chasing speed with clarity. We reach for the 407COMP when we want a bold, uncomplicated 6 MOA dot, and the 507COMP when stage demands or personal preference call for a customizable sight picture.Safety note: Always follow firearm safety rules and manufacturer instructions. If we’re unsure about mounting or zeroing, we consult a qualified armorer or gunsmith.
