Presentation

Red dot sights have become extremely popular, and I consider myself an enthusiast on the topic. You might have read my last comparison between theVortex Defender XL VS. the Holosun 507 Comp, two large windowed XL red dots. Today we are looking at two micro red dots in the same way. We are reviewing the Vortex Defender CCW VS. Holosun SCS Carry, both of these red dots are RMSc footprint compatible, and they both feature an enclosed emitter.

They are very comparable and I expect very popular candidates for folks looking to put a red dot on their CCW pistol. I’ve put quite a few rounds through both of them, and today I’ll give you my opinion on their comparison.

Specifications

On paper these two sights are pretty similar, the main difference in construction being that the Defender uses a dual power source. A removable CR2023 battery whereas the Holosun uses its solar panel as a source, keeping an internal battery (non-serviceable) battery charged.

Both of these are small and ideal for a CCW pistol, but because they are enclosed emitters that means they are slightly bigger than traditional open emitter red dots. The Vortex defender is a little bigger than the SCS Carry, though I’m not sure if thats because of the battery housing or because they wanted to make a bigger window.

Configurable reticles are becoming more the norm, and I like that. Both of these can be configured with a dot, circle, or circle-dot reticle.

On the Range

I’ve spent a lot of time shooting with both of these sights, but in fairness I have more time using the Holosun. I have run the SCS Carry on several different pistols, both 9mm and .22LR. The Defender CWW Solar Micro has lived on my Girsan 2311 since I got it. Realistically though, you can get to know a pistol sight well enough without having to go through a bunch of pistols. Though I did run both sighs on the same pistol for a while to get a solid comparison.

Mounting and Zeroing

The Holosun SCS Carry uses a K footprint, that can also be dropped onto an RMSc footprint. The Defender is an RMSc footprint, so either of these can fit in most of the same mounting situations. I had not issue mounting them on several different similar pistols.

holosun, scs, carry, red dot, holosun red dot, — unboxing the Holosun SCS Carry

When mounting red dots, I usually try and line them up as close to the iron sights as possible before torquing them down. This usually makes for minimal adjustments to zero the sight. The Vortex model has 110 MOA of adjustment available, while the Holosun is plus or minus 30 MOA. That might make the Vortex a little better for certain host weapons, but in general you probably don’t need that much.

The Vortex also gets extra points since it came with a plethora of mounting screws and accessories for mounting on different hosts.

Brightness

One very convenient thing about the SCS Carry is its auto-brightness correction. The solar panel uses ambient light to adjust the reticle brightness. I really like this feature though every so often I wouldn’t, let me explain. Typically in dark areas, I occasionally found that the SCS Carry was a touch dimmer than I would have liked in such a scenario. Outside in daylight I never had an issue.

The Vortex Defender has a manual brightness adjustment, which can be both good or bad. You can set it where you want it, and know what to expect everytime you present the pistol. But you also might have it set a little bright, or a little dim for any particular scenario. I am still unsure which way I prefer, but I kind of default to the manual setting, because I like control.

Sight Picture

Both of these optics are compact, though the Defender is a touch bigger as I mentioned. But the Defender also has a noticeably bigger window, and a little bit means a lot with sights this small. The bigger window definitely gives more room for target acquisition and aiming. Both of them gave precise aiming, but I think I have to give the Defender an edge here.

One thing worth mentioning here, the Holosun SCS Carry does incorporate a notch rear sight as part of its housing. Which is one thing I wish the Defender had, in case the electronics were to fail.

Parallax and Clarity

One thing I noticed with the SCS carry from the very first time I mounted it, was a touch of fuzz when focusing on it. I never worried too much about it as I would look past the sight at the target, and hold the reticle over it. Doing this I never had any issue sharply seeing the reticle.

On one of my test guns, I removed the SCS to install the Defender and immediately noticed the Vortex did not have that issue. Regardless of where I focus the Vortex Defender is sharp and clean, whereas the Holsun SCS Carry did have a little fuzziness depending on how you looked through it.

Accuracy and Zero

With 3 and 2 MOA dots, both of these optics give you a fine aim point. And with an accurate firearm I found them both to be very useful. When zeroing the optics I found they were smooth, and moved evenly. I can’t stand a sight that doesn’t show any change when you adjust it, and both of these were great in that aspect. The quality of these two sights also show in that neither of them needed to be re-zeroed at any point, they held zero nicely, and after hundreds of rounds they hadn’t moved.

Girsan, witness 2311, 9mm, eaa, 2011, vortex, vortex optics, defender CCW, enclosed, red dot, zeroing, adjustment, — both dots were easily adjusted with tools provided

Value

I have no doubt that both of these optics are manufactured overseas, it’s hard to find a red dot that isn’t these days. To be honest I was a bit surprised that the Holosun tends to cost more at popular online retailers. At publishing, it seems the SCS Carry is usually around $400 like here at Primary Arms. While the Vortex Defender CCW Solar Micro is typically priced around $300 like here at Optics Planet. With prices like that, the Vortex seems to offer a significant advantage.

Report Card

You may have gathered, I like both of these sights. But it didn’t surprise me that the Vortex won me over, after a short while shooting it I could tell I was going to like it more than the Holosun SCS Carry. That is certainly not to say the SCS Carry is not a good option as well. Though I like them both I would have to pick the Defender CCW Solar Micro if I had to pick only one. Luckily I don’t, and I can have both of them for different purposes.

Cumulative Score	96%	92%

Last Words

Hopefully this has helped you decide which of the two options might best fit you. Both are certainly good choices for your concealed carry pistol, but it would be a good idea to look at them in person as well to help close the deal for you. Both of these dots will continue to be used in my collection, and I look forward to what’s new from both of these great companies.

Vortex Optics Defender CCW Enclosed Solar Micro red dot

March 18, 2026Optics, Product reviewccw, defender, micro, Red dot, rmsc, solar, Vortex, vortex opticswcoldboremiracle

Prologue

Enclosed red dot sights are becoming more and more popular, and I decided recently that I’d jump into them with eyes open. Today we are taking a look at the Vortex Optics Defender CCW enclosed solar micro red dot. Part of the larger Vortex Defender family, this model encloses the emitter and adds a solar power supply all in a micro red dot that drops onto the popular RMSc footprint. We’ll review this sight and give you some feedback on it and how it stands next to its competition.

the Defender CCW was a perfect fit for my Girsan 2311

The Vortex Defender CCW

I’ve had a couple other Vortex Defenders recently, and I quite liked them if I’m honest. So it was with some confidence that I decided to match this new Defender with my latest 2011 style pistol. My Girsan Witness 2311 has an RMSc footprint machined into it’s slide, so I wanted to put a good enclosed sight on the pistol, which led me to the Defender.

The Defender CCW Enclosed Solar Micro Red Dot (ESMRD) is a tough built dual-powered sight. It’s large window houses a configurable reticle inside its protected weatherproof housing. This dot is made to fit large weapons down to sub-compact handguns.

Like other Defender dots, this one came with an incredible selection of accessories. A great variety of mounting screws in various sizes, an one-degree angle shim, mounting and adjusting tools. As well as a picatinny mount, and a cute little rubber cover.

Mounting the Defender

After removing the sight from my pistol, I sat down to mount the Defender ESMRD. Using a set of screws that came with it, I did a few test fits to ensure it would be properly secured. I always like to put a touch of blue Loctite on the threads and under the screw-head. Nothing worse than your red dot coming loose while shooting, so I snugged it down nicely with the included tool. I love that Vortex red dots come with basically everything you need to mount them.

Powering up the Defender would require removing the battery cover to remove the battery isolation sticker. After which the reticle lit up and allowed me to give it a rough adjustment before heading to the range.

Range-time and Zeroing

Zeroing the Defender was easy, lining up the reticle with the sights as I torqued it down. After that, with a few shots I made some adjustments with the included tools. In no time the Witness 2311 was hitting my point of aim.

We would shoot quite a bit at an indoor range the first time. Getting a good feel for picking up the reticle and focusing on targets. Following the instructions I cycled through the three reticle configurations, this is done by pressing the + and – button together. You can select between a 3 MOA dot, a 32 MOA circle, or the two together. I am a bit of a circle dot kinda guy so that where it typically stayed.

You can also lock out the buttons to prevent unintended adjustments. Pushing the + button and holding down until the reticle blinks, and easily reversed by doing the same process till it blinks twice.

According to the manufacturer, the Defender Solar Micro will last approximately 35,000 hours on a battery, using the 3 MOA dot with no solar input. That might be the case, but I wasn’t going to find out. As I like the circle dot configuration, and there would certainly be some solar input since I usually shoot in the daylight. But furthermore I was going to engage the auto-shutdown feature that is a must for red dots these days. By holding both buttons down you can engage or disengage this feature.

Optical Performance

While I am not a huge fan of the “mailbox look” , this red dot is a bit larger than other options because it is an enclosed emitter. Its very comparable to other enclosed emitters of the same size, and has a large window. For a micro red dot It certainly felt like a big lens.

Girsan, witness 2311, 9mm, eaa, 2011, vortex, vortex optics, defender CCW, enclosed, red dot,

I did feel like the Defender CCW Solar Micro had less color change when looking through it. And I also really liked how sharp and clean the reticle looked. No parallax made it easy to focus on whatever I wanted to shoot.

Usability

Adjustments and controls of this Defender were easy to understand and remember. Its included tools made it easy to zero the reticle and the included directions explained everything nicely. I like the dual power source, and the battery is easy to change without removing the unit from the host. I also like that they used the CR2023 battery which is more common than the other options typically used in micro sized red dots.

Value

MSRP on this red dot from Vortex’s website shows $400, but as usual you can find this red dot on places like Optics Planet for much less. I have other similar red dots that retail for more that I don’t like as much as this Defender. Even if you broaden the search to other larger red dots of different footprints, I still think this one offers more for less.

Pros and Cons

First off, this thing is handsome. And we can’t pretend that doesn’t matter, it looks like a great quality fit for nice handguns. The controls are easy and comprehensive, external battery mounting and the plethora of included accessories and mounting options make it a slam dunk. Its big clear window makes for quick finding and engaging of targets, and the reticle selection is a big plus. All this for a reasonable price when compared to others.

If there was anything I would change about this red dot, it would probably be a bigger circle option. Nothing wrong with the 32MOA, but I wouldn’t mind like a 50 or 60 MOA circle option too. But of course these are subjective preferences. I also wouldn’t mind if they incorporated a notch on the base to double as a rear sight if needed.

Concluding Thoughts

Every time I get a new Vortex red dot, my inventory of fasteners and tools is enriched. Vortex packs some great added value with their red dots, and that’s a pretty big feather in the cap for this sight. My selection of Defenders continues to grow, and this one is probably my favorite so far. The simple controls and all the options are what seal the deal for me. I am uninterested in red dots moving forward that don’t have auto-shutdown, this and other features make the Defender CCW Solar Micro very adaptable to various applications. I look forward to the bright future and reticle with this combination.

Holosun SCS Carry Red Dot

October 17, 2024Optics, Product reviewholosun, Red dot, rmsc, scs, scs carrycoldboremiracle

Preface

I’ve jumped into the red dot world with both feet at this point, and fully embraced optics ready handguns. This has resulted in a wide variety of red dots making their way into my collection, and today I am bringing another one to you. Today’s subject is the new Holosun SCS Carry red dot.

The SCS Carry Red Dot is a compact RMS-C sized red dot that will fit onto compatible footprints. Like other Holosun K optics, this red dot is ideal for compact carry guns. But this little unit has some additional features you’re going to like, as did I.

The Holosun SCS Carry Red Dot

The SCS (Solar Charging Sight) uses solar energy to power itself for an indefinite period of time. Perhaps in the dystopian future, in the fight against the machines, someone will find one of my old pistols discovering a curious green glow.

The SCS Carry has an internal rechargeable battery good for over 20,000 hours. And since it is constantly recharged by the solar cell on top of the unit, you can count on it outlasting your ammo supply. In addition to the power cell, the SCS uses multi-directional light sensors to adjust reticle brightness depending on ambient light.

Holosun is very popular for their reticle options, and this one is no different. The SCS comes with a 2 MOA dot and a 32 MOA circle around it. I like this pattern and have used it extensively in my Holosun 507 Comp red dot on another gun. This model also features an enclosed emitter for reliability, as well as a notched base to stand-in as a rear sight.

Other traditional Holosun red dot features are also incorporated, things like the 1X magnification, lens coatings, unlimited eye relief, and parallax free viewing.

Assorted Models

Aside from the model shown here today, there are also other models of the SCS Carry. There is a non-enclosed emitter version that is less obtrusive and surely lighter. And there are also firearms specific models as well, with SCS Carry dots made to fit: Smith & Wesson, Walther, Sig Sauer, H&K, and CZ pistols respectively. These custom fitting sights likely reduce your need to use adaptor plates, and other mounting hardware. Both simplifying the install, as well as reducing the weight of your CCW handgun. The SCS family also incorporates Holosun’s Super LED technology, matching visual wavelengths of light best seen by most eyes.

Mounting the Holosun SCS Carry

Mounting the SCS Carry was easy using the provided tools and fasteners. I chose my Taurus TX 22 Toro as a host for the SCS, mainly because it was available and needed a red dot. In addition to that situation, the TX 22 is an incredibly fun gun to shoot, you can read more about it here.

I lined up the reticle as best I could while torqueing down the mounting screws. This would help reduce the adjustment needed to zero the optic, and with a few clicks it co-witnessed perfectly with the iron sights. I could adjust it a little more once on the range. I also appreciated that they kept the base thin enough to still be able to see my iron sights through the optic.

After mounting, I took a moment to go through the operating instructions. Its convenient to not worry about brightness settings, and I was amazed at the instant adjustment of the auto-brightness controls.

Shooting the Holosun SCS Carry red dot

Once in my shooting spot, I started loading magazines to pour a fresh layer of lead on my targets. The bright green reticle of the SCS was easy to see even in the bright mid-day sun. After a couple adjustments, it was dead on. We spent the afternoon burning through ammo, and drawing down on targets.

I also keep that pistol close during hunting season. Its always nice to have a suppressed 22 handy for quietly dispatching pests without scaring away the elk and deer. It also gave me something to do around camp, plugging mice in the dark with a Surefire X300 weapon light attached to the pistol.

Shootability

I like the big-windowed red dots, so it was a little bit more restrictive using the smaller window of the SCS. That is of course to be expected with a smaller optic, it also requires you to be a little bit more judicious when presenting the pistol, making sure it’s lined up. The SCS Carry is ideal for a carry sized pistol, its width is similar to many compact guns, and its edges aren’t snaggy.

The enclosed emitter is nice, as it keeps debris from getting between the lens and the LED. I did notice a tiny bit of blur when shooting, though I’m not sure if it was due to looking through two pieces of glass or something else. I know most of these optics are supposed to be parallax free, but occasionally it feels like maybe they aren’t. Or perhaps my eyes are starting to go…

Either way, the SCS Carry was great for shooting. Always ready, always on.

Reliability

Which brings us to our next point, in all my shooting the SCS was fixed in its place. Never did I have the need to re-zero or adjust anything. Nor did I have any issues with the controls. Its simple, which I have on good authority is good for stupid’s like me.

Being exposed to freezing temps, vibrating for miles and miles on ATV’s didn’t slow down the SCS Carry. The only maintenance needed was to clean the front lens occasionally due to suppressed shooting.

Accuracy

As I mentioned already, I never had to readjust the SCS Carry. It maintained zero throughout all this. While the recoil of the TX22 is not as significant as some of your spicy CCW 9mm pistols, it still endured lots of shooting. Maintaining zero is very important for all sights, but particularly for CCW sights.

Also I mentioned window size and my preferences. Training with what you are going to carry and shoot is probably more important than preferences. And shooting accurately with the Holosun SCS Carry was perfectly attainable with proper practice. The reticle details also gives you a few advantages as well.

The MRS from Holosun is a nice customizable feature, the Multiple Reticle System gives you options. You can select just the 2 MOA dot for more precise shooting, or you can use just the circle to bracket targets. Or a combination of the two if you choose.

Value

There are untold hordes of red dot sights on the market now, making it very competitive. I can appreciate that Holosun’s Optics have maintained a great position of authority in that market. They continually push the boundaries, innovating and bringing new features and options. Basically they seem to be the ones to beat. The Holosun SCS Carry line of red dots are not the most affordable red dots made by Holosun, but I wouldn’t expect a dedicated CCW sight to be so. Sure you can get cheaper red dots, even from Holosun. But the feature-rich and maintenance-free SCS Carry is well worth the extra cheddar in my opinion. If you’re looking for a good sight for your CCW pistol, the street price between $350 and $400 for these is a great choice. It’s no surprise they have a “best rated” tag on Optics Planet.

Pros and Cons

There was very little I could come up with that I didn’t like about the Holosun SCS Carry red dot. I’d mentioned earlier some possible blurriness, though I’m not sure if its me, dirty lenses, or something else. It was certainly not enough for me to worry about.

Everything else about the SCS Carry was great for me. I love the simple operation, never needing to worry if it’s on, or having to adjust the brightness when I go indoors or out. It fits a wide variety of guns, it’s emitter is enclosed for less cleaning and maintenance, and I like the bigger reticle. And it comes with most everything you need to mount and adjust it, adding to my collection of red dot mounting hardware and tools.

Conclusion

If you haven’t gathered by now, I think Holosun has hit the target with this little optic. It gives great performance with no complications. It adds just enough to your CCW pistol to be beneficial and give you the upper hand when aiming. While shopping for your next pistol sight, consider the Holosun SCS Carry as a solid option. I’m not sure if this one will stay on my 22, or if I’ll move it over to my CZ P-10S.

Pistol shooting, like most shooting disciplines has benefited greatly from technological advancements. Incredible improvements have made todays handguns lighter, faster, more accurate, and reliable. One of these many improvement is in the sight market, pistols have long relied on the simple task of lining up a front and rear sight as you press the trigger. But today we will discuss the hot and competitive red dot sight options that are frequently replacing traditional iron sights. We’ll also look at it from the perspective of home defense use.
