The Trijicon SRO (Specialized Reflex Optic) is specifically designed for pistol use. Improve shooting accuracy and speed with the wide circular field of view and clean, crisp dot making it easy for users to find and track while shooting. Every SRO has 8 brightness settings with "Lock-In" and "Lock-Out" modes and a 3-year battery life. The SRO similar to the Trijicon RMR easily mounts to popular red-dot-ready pistols, is compatible with most RMR mounts, and does not require a sealing plate. There is no need to dismount the optic for battery changes with a quick-change top loading battery. The SRO is designed to survive the rigors of slide ride pistols and is engineered for hard use. This 5.0 MOA Adjustable LED red dot is best for applications in which speed and recovery of the dot is critical such as in competitive shooting

If mounting to Glock MOS the screws in kit AC32085 will be to long. Screw length in kit is .380. You will need screws that are .375 in length so you don't have to use the unnecessary sealing plate. .380 screws will work if sealing plate is attached. But why use sealing plate if SRO doesnt require one. You will have to call Trijicon tech support to get .375 length screws.

Great optic for shooting Carry Optics (CO) divisions in USPSA and IDPA. I've used a ton of different optics for CO. This combines the best features of all that I have tried while still being Trijicon durable. I have one on my Glock 34 with just over of 8,000 rounds so far and no issues. Just started rocking my second SRO on my Walther Q5 SF. Only 1,200 or so rounds on that optic but it is running strong and works so well. 5moa is THE answer if you are planning on using the SRO for practical pistol competitions.

Works baller on a Shadow 2 and the EGW mount. Ran it in a match and spanked A zones. If you're looking to buy skill, buy this.

I just put the SRO on a new PDP. I currently have 3 DP Pro's on other pistols. I wanted to see if the SRO would have any real benefits over the DP's. In short, the SRO can be set MUCH brighter and there's a little more vertical height to keep the dot in view for faster follow-up shots. The SRO has no perceivable parallax, but does have some "fish bowl" distortion around the circumference of the glass. This is only slightly annoying. Buttons must be pressed pretty firmly to activate, and no tactile feedback. Overall, I would buy this over the DP Pro for new pistols, and I think it's an excellent red dot. I do still love my DP Pro's and have no desire to replace them. Both are excellent quality. Thousands of rounds through the DP's without a single issue. Only 200 rounds through the SRO so far.

The Trijicon SRO is a great red dot. The window is big so the dot is easy to find. I have 4 of them on various pistols. Their durability is great and the one mechanical issue I had, Trijicon took care of immediately. They replaced the sight.

I bought the 5 MOA model to mount on my Staccato P and much prefer it to my 2.5 MOA model mounted on another pistol. Eurooptic had a great price and the SRO was at my doorstep in a few days. I will definitely shop here in the future.

Absolutely amazing!! Hands down one of my favorite red dots. I purchased this back at the beginning of 2022 and didn’t feel inclined to write a review from the day I received this product in the mail. I added this rdo to my beretta 92 and since then have put over 5k rounds with ZERO malfunction ZERO adjustments. This is a ridiculously amazing piece of equipment and can’t praise this enough. Only thing I haven’t done is purposely dropped it which I don’t this is necessary. I will definitely be buying another from euro optic because of the great pricing and great service

I have nothing bad to say about it. It's mounted on a Gen 4 Glock 21 with slide work by Jagerwerks. Credit to both JW and Trijicon, as it dropped right on and was already zeroed. Only around 150rds through the gun with it on so far, and some dry fire work. No issues. Would definitely buy again or recommend.

Purchased the Trijicon SRO from Euro Optic and couldn't be happier! Not only is the SRO top-notch for competitive shooting, thanks to its wide view and crisp dot, but Euro Optic's service was outstanding. The shipping was lightning-fast, and their customer service went above and beyond to ensure satisfaction. The ease of battery change without dismounting is a game-changer. Highly recommend both the SRO for its durability and Euro Optic for their excellent service!

Awesome shipping and service from Eurooptic so no complaints to them. Trijicon definitely needs to improve their quality in terms of mounting hardware. When I initially went to install with the supplied screws, one screw broke off at the slide and had to be drilled out. Screw wasn't crossthreaded or damaged when removed. Fast forward a week, and both screws sheared off at the slide while shooting, tossing the SRO downrange. I've since ordered aftermarket titanium screws for mounting because apparently for $500, Trijicon can't supply screws that last more than 500 rounds of competition shooting. The optic itself is great, but no optic works well when it can't stay mounted to the gun.

This is my third Trijicon SRO. It feels very robust. I feel like it can be dropped on concrete and still function with no problems. The buttons are more tactile than other red dots that I’ve had. The window is fairly large. The dot and window is clear. I shoot USPSA and was a LEO for 22 years. If my old department had red dots on their duty weapons back then, mine would certainly have an SRO. I only wished that the housing around the lens was a little thinner.

The Dot functions as it should for a 500$ optic. Now when it first showed up, that wasn't the case... there was a straight red line being refracted from the ledge the laser sits under. Oh well every company has QC issues these days it seems. BUT EUROOPTIC had me a replacement shipped next day, after mine was delivered back. Total turnaround from purchase of faulty sight to delivery of perfect red dot was less than a full week. The sight is easy to zero, dot is crisper than other brands I have. Yes buttons are stiff on these.. I would buy again and definitely from EUROOPTIC.

I bought the SRO to use on a USPSA Carry Optics pistol. I was previously using an RMR. The SRO window is significantly larger than the RMR. I can't comment on reliability since I've only had it for a few weeks now. The dot brightness and quality are great.

Love the big window of the SRO and love the durability of the RMR. Hopefully some day these two will have a love child and give us the best of both. I run both sights on different guns and have to admit the SRO is more fun to shoot, but the RMR is the better carry option. But these are tools and it’s always best to use the right tool for the job and the SRO is definitely the right tool for a range gun.

I honestly was very hesitant like most things buying anything off the internet, especially on a site I recently came across but I’m extremely happy with euro optics and this 5 MOA red dot sight. As a first time buyer of a trijicon product and euro optic customer I’m very happy, my beretta m9 with a modified slide that houses an sro sight is unbelievable amazing. I’ve had this red dot for about 4 months now, I shoot at least twice a month and put about 1k rounds of 9mm through my beretta m9 with this sro and it holds zero 100% and doesn’t disappoint. It was really simple to zero in( did it while I saw watching a movie but later slightly adjusted it at the range). I’ll definitely be buying this again from euro optic again once a buy another gun, price is more than fair,actually the cheapest I’ve seen, other site average $530-700+ (ranging all MOA sro)

Have about 1,000 rounds through it so far and it's exactly what I wanted. Large window, crisp dot, and handles the Texas sun. Brightness adjustment buttons aren't tactile, so it can be difficult to know at first when you've pressed it but you'll figure it out quickly. Windage and elevation adjustments are very tactile and easy to use. Has some blue notch filter to aide in the long battery life but doesn't cause any issues when actually firing. Glad I upgraded.

Obviously this optic is bigger than an RMR so requires a little more effort if you wish to CCW with it but as far as shooting the dot it is awesome. Also a great option for people transitioning to the dot or range/competition and HD.

I was unsure of which Red Dot would be best for my gun so I chatted with Kyle who asked a few questions and recommended the Trijicon SRO. Thank you Kyle! It is perfect for my intended use. It's adjustable, easy to use and set up. 100% satisfied!!!

Light weight & small red dot for your pistol, rifle, or shotgun. I'm going to pick up a few more of these for multiple platforms. I prefer this over their RMR. It's Trijicon, so QC is always pretty good. And then there's EuroOptic, with their always fast shipping and great prices that continually get me in troube with my better half. Thanks!

I like the SRO optic, it's clear, and the controls are easy to use. You would think for what you have to pay for one of these they would at least include a cover. I think I'll stick with Vortex going forward. I can't see that this is worth the price difference.

I own 8 of these red dots. Big window, easy to find dot, and the low profile base allows for fast dot acquisition, fast target acquisition and co-witnessing with iron sights. Adjustments are easy to make because the notches allow you to use an empty brass as a screwdriver.

Trijicon needs to ramp up their quality control. First SRO I received had a huge silver blotch where the glass and frame came together. EO customer service did an amazing job and promptly replaced it. However the second SRO I received, the gasket above the battery was pinched/torn. I didn't bother returning the second SRO but Trijicon, get your act together!!! Make sure you double check everything on your SRO when you receive it.

Do you like finding your dot fast and 100% sex appeal on your handgun? Maybe you like flexing with your PCC or backup dot on your AR. If this describes you then the SRO is what you need. Don’t waste time and money on those other dots. Bigger is better and the SRO never fails to please. 1, 2.5, 5, they’re all great. Can’t make a bad choice when it comes to this sexy lil thang.

The buttons on my Trijicon SRO Sight Adjustable LED 5.0 MOA Red Dot SRO3-C-2500003 have no tactile responce ... its difficult to even push them push them once I've found the right spot on the rubber pad to push .. just not what I expected from a $500.00 site .... Its okay if you dont mind fiddling around with the controls trying to find the sweet spot to make it turn on and off... I spent a lot of time deciding which site I wanted to purchase and I was very pleased with the aesthetics of this one when I saw it ... just wish the functionality mached .

My first match as a C shooter 4 months into USPSA had me harrassing the GM guys with my SRO mounted Shadow 2. Was blazing like Nils with a $400 Canik. Then I woke up and realized the SRO still hasn't shipped. Hopefully the SRO performs like it does in my dreams.
