TrijiconRM01 RMR 3.25 MOA LED Red Dot Sight

In January I got the 6.5 MOA version for a Glock 26 with a Brownells RMR cut slide and loved it. Recently I got this 3.25 MOA version to put on a new Glock 19 Gen 5 MOS. Once again I love it. Don't sweat the dot size. I like each about the same and got the smaller dot this time because it was cheaper on the day I bought. On a pistol you can't keep your hand steady enough for the differences in these two dot sizes to make any difference.These things greatly increase the fun of target shooting, especially for folks with bifocals. Gone are the days of tilting your head back to use the bottom of your glasses to focus on the front sight. And gone are the days of closing one eye to shoot (I tried shooting with both eyes open on iron sights and could never make it work for me). Now I can focus on the target with my head in any position I want with both eyes open and shoot.Besides the added comfort, the red dot just blows iron sights out of the water for accuracy. My little Glock 26 with the RMR is significantly more accurate than my full size Glock 17 with iron sights, and if you want to fast fire you can get the red dot back on target a whole lot faster than you can get iron sights back on target.The only negative with these sights, and one I have not had to experience yet, is that you have to remove the sight to change the battery. This apparently only needs to be done once a year at worst, but I don't look forward to doing it. Getting the sight back to zero doesn't worry me - that is quick and easy. I worry that the Loctite (blue) on the screws will make it a real chore to get them out and worry about stripping the screw head. I have good tools so hopefully I am needlessly concerned. I would strongly advise against using the little wrench that comes with sight - get a Wiha, or other good brand, screwdriver. I was sure glad I had one when I took the cover plate off the Glock 19 MOS. Those screws had a Loctite type substance on them and took a good bit of force to get out.I now have well over a thousand rounds through my Glock 26 with the RMR and a couple of hundred through the Glock 19 with this RMR and have never had the slightest glitch with the RMRs. I trust the RMR enough that the Glock 26 is now my carry gun - though with suppressor height iron sights, just in case.

I put this on my Glock 41 MOS (will fit any Glock MOS model) and it is like cheating when you shoot! It makes target acquisition so fast and easy that others I shoot with want to use my pistol. If you are looking for a good red dot this is one of the best. And mine is used several times a week as I run 3 gun ranges at a police academy and it is worn and carried daily. The thing that I like about this sight over some others is its always on. That means carrying this as a concealed or open carry firearm you do not have to worry about turning it on and off. It's always on. And my sights are not OEM, they are high rise Trijicon night sights also and they match the red dot when all are lined up. Great in case the red dot battery should die and I do not notice it. Also if you are an instructor teaching, having the red dot line up with the sights is very helpful when explaining sight alignment and sight picture. It is a great teaching tool also.Rounded corners so nothing to cut or snag you on. As you can see in the second photo I use it at work also.PROS:Battery Life is VERY longRounded Corners so no snaggingEasy to line up and acquire the red dotAble to use high rise co-witness sights with it so never without a sighting system, even if it goes out for some reasonTrijicon Customer Service is great!Not to big to prevent it from being on a CCW firearm.Great field of viewCONS:None that I have found yet.Trijicon RM01 RMR 3.25 MOA LED Red Dot Sight

Two years and still going strong. When I think rugged, I think Trijicon.

Extremely satisfied. Here's some context on other reviews and their associated concerns:Yes, it's always on. In my opinion that's a better option as it's also always ready! Other models night illuminate with tritium. Eventually it wears out but you can always replace batteries. Store in a dark spot (safe is perfect for many reasons) and you'll get long battery life.The battery is exposed on the bottom. I paired this with a ZEV Tech Gen 4 slide. Zev supplies a stainless steel gasket that mates on the underside of the RMR and top side of the slide mounting surface. I also placed a small piece of electrical tape for another safeguard. No issues with the red dot dimming and I'm confident that the seal is water tight.I pared this RMR with Trijicon Suppressor sights lined the dot up very slightly above the front sight and it shot a 1" group dead on bullseye at 20 yards with factory Winchester whitebox ammo. I used a little blue loctite on the mounting screws when installing and absolutely no issues with POI shift or the sight coming loose. I find the 3.25 MOA option provides quick target acquisition, provides adequate sight picture for steel targets or standard paper targets for precision aiming, and it matches very closely with the size of the rear and front sight aiming dots so it feels familiar and natural.Yes, the price stings s little but this thing is ruggle, reliable, and will adapt to just about any weapon system. Also trijicon's warranty should put you at ease.
