This is my second SRO 2.5 in two weeks. Put it on a already made optic pistol from the factory. The optic was easy to dial in at 25 yards. Every thing went smooth until it began to sprinkle (outside range) and the glass on the optic lost it's dot. I wipe if off and the dot finally came back. Other than that It was great. Will this optic hold up in bad conditions? I served in the Vietnam war the late 60's in recon and I believe this optic would have failed during that war. However, most of the optics would have failed as well. However, this is not the swamps of Vietnam or the beaches of Normandy. I am a firm believer this optic would be good for EDC. I have two and love both of them

Probably the best pistol optic available. I have three of them now. The 2.5 MOA dot is ideal for handgun shooting. The large, more rounded window makes target acquisition easier. It costs more than an RMR, but the top-access battery compartment and not needing a sealing plate make it worth it. If there's a negative at all, it's that the design could cause the front of the optic to extend over the ejection port on smaller handguns. Not a problem with my G19, G17, or XDm.

This is my 3rd SRO in about three months. It was installed on a IWI Masada ready made for an optic. The gun was known as shooting low from all the reviews mainly because of the stock sights. SRO solved that problem as it was dial in about 25 yrds. My only concern with the gun was the SRO optic was sitting real close to where the rounds would come out. After several hundred rounds there was no issues. After owning three of these optics I still prefer the manual mode the best. So for I really like the open view it gives and it seems to hold zero on all three optics. I am near sighted and when wearing glasses the dot and target are very clear. Can't say that about iron sights. Iron sights will always been around and hard to beat. I do believe optics on hand guns are getting more popular all the time. My groups at 25 yrds are closer than iron sights and so for I am a fan of the SRO.

This is my first SRO and when i compare it to my Leupold delta point pro or even my eotech flex there is no competition. Trijicon takes the gold with this optic. Its like shooting your gun through a 20 inch screen tv to then changing over to a 70 inch. I will probably never go back to anything honestly. This optic is mint and i have zero complaints.

First let me thank Euro Optic for providing great products at very good prices & outstanding customer service. I have all three SRO’s. They’re great optics & each have a preferred use, but IMO the SRO2 2.5 MOA is a very happy medium for any use.

Running the SRO 2.5 on my Staccato XC definitely makes me seem like my skill levels are more than they really are LOL. Put about 1000 rounds through it and the dot is amazing especially for my astigmatism. The large window allows me to find the dot with both eyes open and stay on target even during rapid fire. Eurooptic is also my go to for ordering optics. Everything about the ordering process, shipping was smooth. Def will be buy another SRO 1.0 moa soon.

I have owned quite a few different optics but I have never owned anything like this SRO 2.5 MOA. I took it for a walk this morning at my indoor range, I zero'd it in and it stayed with me the entire morning. I adjusted the brightness just a touch and found the dot every time. I was a little hesitant on ordering the 2.5 vs the 5.0 but since the 5.0 was out of stock and I am not the most patient individual; the 2.5 is what I would recommend to anyone. Euro Optics customer service is the bomb! Just get yourself one of these optics and enjoy shooting again.

The SRO is pretty cool, no complaints, but I'm really leaving this review to explain how ridiculous these people are when it comes to shipping products. Order a product at a godforsaken hour and they've already shipped it before the purchase receipt has hit your inbox, it's insane. This is hyperbolic, but only slightly!

I was skeptical about it being too big for concealing, but man! It’s totally worth it, there’s less distortion than a normal RMR and a crisp dot. Definitely recommend buying the SRO tool for changing the battery but otherwise so far it’s been great!

The SRO is every it the quality optic you hear about. As I get more comfortable using an optic I'm thinking that a 5 MOA dot would also be very useful, but the 2.5 does the job and seems to be in the sweet spot. Price was excellent, shipping fast and service was great - I'll be shopping for other items in the near future!

This was the third Trijicon SRO I have purchased from Euro Optic. My first one was put on my Sig P220 Legion SAO in 10mm. It brought this gut from terribly accurate to an absolute beast and makes it almost impossible to shoot anything but perfect hits. My second SRO went on my Springfield TRP 6" 1911 in 10mm. And, again, the SRO brought out the best of this pistol. I purchased my third SRO for my Springfield 1911 DE Prodigy with a 5" barrel. Normally, I would have used an RMR instead of the SRO, but I am so glad I went with the SRO. The Prodigy shoots fast and the oval glass of the SRO makes picking out the target so much easier and faster. I went with the 2.5 moa dot rather the 1 moa dot as I carry all three pistols as an off-duty option and the 2.5 gives quick acquisition with plenty of accuracy. While I know there are many lower cost options, I want something I can bet my life on. And with the price Euro Optic sells them for, I will keep using SROs and RMRs on my carry pistols.

This is my first red dot sight and I'm very pleased with it. Easy to install, easy to operate and ridiculously accurate right out of the box. I liked it so much that I bought a second one. I know Trijicon has been around for years and has a great reputation for making high quality products and this sight does not disappoint. It also came with a free decal and nice storage case, that's always a bonus for me.

Absolutely fantastic optic! The large objective feels like a big safety blanket while shooting, plus the glass is super clear. All adjustments; whether brightness or dialing in zero, can be done easily without any fancy tools. The battery can be accessed through the top so you don't have to re-zero your optic everytime. I highly recommend this to anyone who wants the added security and sight picture when it counts most and the people at Euro Optic were superb in the shipping and handling! Super fast and efficient, thank you!

If you are into competitive action shooting or are just new to red dots, the SRO is a worthy investment! The large field of view is really beneficial in finding that dot when torquing around obsticles to acquire a target, or just learning to present the pistol. I just put this one on a P320 Pro. Just make sure your Pro slide has the second set of threaded holes in the optic cut. Some of the earlier runs do not have them. A great product at a great price from EO!

I have 2 SRO 's. I used one to replace the Cmore on my STI DVC Steel. Lower bore axis, shorter mounting aera, outstanding optics and does not lose adjustment. I put the second SRO on a new VP9 Tactical . It made the gun much easier to shoot for me. Fast aquisition, clear sight picture and a huge advantage for older eyes with bifocal glasses. Very pleased with this product.

On 11/16/19 I got a Walther ppq q4 tac ready made for an optic. I took it to the range to make sure the gun was working after about 150-200 rounds and it was. Dial it in with iron sight at 25 yards. After much reviews on the SRO I wanted to see what all the hype was over the SRO. This would be my first optic on a hand gun. Three days after my order I put the SRO on my Walther. Just a little over 100 rounds the red dot disappeared. I shot it again without the dot and it came back on. This happen three time in a roll and I knew something was not right. I called Trijicon after waiting about 12 minutes on them and told them what was going on. He said make sure the battery cap was tight and if it wasn't it could cause this. I turn the cap about 1/4 of an inch and took it back to the range and the problem never happen again. Problem solved. I dial the optic in at 25 yards and it was shooting groups tighter than my iron sights. I was shooting at a piece of typing paper at 25 yards with iron sights and groups were really good. If I can put 8-10 rounds inside of a man hands with iron sights I am please with that with a full clip. However, with the optic I was putting all the rounds inside of a man hands at 25 yards. Are iron sights faster than the optic? It depends on how you present the optic and if your looking through the glass trying to find the dot instead of the target the iron is faster. However, if you present it right the SRO is just as fast if not faster especially with more precision shots. The more you practice with it (dry runs not pulling the trigger just learning to present it right) you will love it. Eye sights. I am over 70 yrs old and I wear contacts/ or glasses mostly contacts. With iron sights my front sight is a little fuzzy with glasses/contact but with SRO everything is supper clear. Rapidfire. This is what amazed me more than anything shooting at typing paper 25 yards I was able to hit the paper at lease 10 times out of a clip. As of now I am sold on this optic SRO 2.5 I kept it at its first setting the smallest dot. The second was good too. I preferred the manual mode over the lock out where it's suppose to adjust to the lighting dark/light etc. In the dark (I mean dark) barely could see the dot. Inside/outside it was OK but preferred the manual setting. Also I want to thank this company for their quick service and also I want to thank Trijicon for adding a scripture verse on the optic.

Great optic. I like it a lot better than my RMR. I was up in the air between the 5MOA and the 2.5.... as my rmrs are 2.5, I've heard good things on the 5. But I went with what I know and I'm very pleased. The shipping time with Euro Optic is unbeatable. I received my optic on the 2nd day. Great job, I will continue to get my optics and accessories from EuroOptic! Two thumbs up!

I have nine handguns and two shotguns with Trijicon RMR or RMRcc red dot sights and I thought the RMR's were the pinnacle of red dot performance. The Trijicon SRO I purchased from Euro Optics makes me wonder how I ever survived without it. The oval viewing field gives me more situational awareness and I feel I i come up instantly on the dot with no problems. I put this sight on my beloved Sig Legion P220 SAO in 10mm. It enhances the inherent accuracy of the platform and the round and makes me wish it were my duty gun. Great product from Trijicon and a great price from Euro Optics.

I had the RMR mounted on my HK VP9, then I shot my friend's gun with an SRO and I just KNEW that I needed to get the SRO for my VP9 and CZ Shadow 2 OR. The window is so big which makes the dot easy to find. The controls are easy to work and the instructions are easy to understand. With the battery compartment on the top of the RDS it makes it so much easier than the RMR and I don't need to re-zero my RDS if I don't want to. GREAT PRODUCT purchased from a GREAT company.

This is my first SRO but I have used many RDS' on multiple platforms. I DEFINITELY am pleased with the 2.5 MOA dot. The 1 MOA and 5 MOA are probably both great but I'm personally not a fan of a 1 MOA dot on a pistol and I'm using this on a XDm 5.25 so I can afford a little more precision than a 5 MOA dot, however if average home size engagements is what you're buying this for, the 5 MOA would be better in my opinion. For my needs the 2.5 MOA dot was perfect and I am very pleased with my choice. Excellent field of view, holds zero, light, profile difference compared to RMR is negligible. I don't personally notice any difference at all between the two. The controls and functions are intuitive, I read through the manual once and tested out the lock in, lock out, on, off, auto-adjust, and manual adjust function. Fantastic sight. Highly recommend! Best on the market and worth the additional cost. Thanks eurooptic for the fast turn around. Ordered on Tuesday, here on Thursday.

I am an LEO, and run this on a duty gun. I love the larger field of view, and the fact that the dot never leaves the screen under recoil. A larger window means more information, more info means I make a better shooting decision. I greatly prefer it over my RMR type two it replaced.

Almost like cheating. If you have a decent grip the dot never leaves the window during shooting. This is my second sro and after putting 7000+ rounds thru it on a Roland special Glock I’m sure this one will run with no problems

I can’t rate the product. On your site it says no optic plate required. When I received the SRO and went to mount it I realized you do need an optic plate. Walther sends you one for free but I’m still waiting. I wish you would have made that clear so I could have gotten the plate on the way sooner or got a plate from you.
