MeprolightMepro FT Green Bullseye Rear Sight - Fiber-Optic Day/Night Sight, Tritium Powered Pistol Optic, No Battery Required, Fits Most Holsters

It fits PERFECTLY on my Glocks but for the record, this is a really awesome iron sight. I feel like we’re a lot of people go wrong is they try to think of it as a red dot and that’s simply not the case for what I found out. Maybe around 3 to 5 feet away then absolutely you can keep it centered like a red dot but once you start getting more closer to 10 feet and further that’s what you need to start aiming lower to get your shot right where you want it. From my experience, I need to get the small dot to touch the bottom of the big circle for my aim to be true and it works perfectly every time. Ofcourse it’s very unique and you need to get use to it and that’s where dry firing comes into play. Unfortunately, this sight is not for everyone, but I highly recommend this sight for those who are patient and don’t mind starting over.

What it is:- A night sight, it will glow in complete darkness. It's bright day or night, if it isn't then it's old or faulty.- A combat sight, it is not for accuracy as in target shooting. It is for quick defense shooting.It's an amazing sight that is easily picked up no matter the lighting conditions. Mine on a G26 hit where I put it, as long as I put in the work. Sure groupings aren't as tight as traditional sights from longer distances but a 10 inch plate is easily hit at 25 yards repeatedly.Think of it like a hybrid to using a red dot, as it kind of mimics that. The only thing is there is no real adjustment left or right and none up and down (one could shim a little I guess for elevation). It isn't a concern really though as the sight again is meant for torso sized targets not bullseye.What it does beat a red dot at is size and weight, it's small and sleek. It's not going to snag or gouge, it's not going to make a carry package larger. So for a defense weapon, especially like the G26 (and brethren) it's a perfect option for many.In the end sights are personal and everybody like different things, personally this is going to be my go to defensive night sight setup. It's not cheap at about $130 to $140 but that's close to many other higher end brands, so not a huge deal to me.

Sorry saw a one star review here from a guy claiming to be some kind of firearm instructor. :) Really good sight if you know how to use it and what it's limitations are. This isn't for long distance shooting. This IS for personal defense distances. Practice with it before you need it. It gets intuitive quickly with a little practice and is very accurate out to about 15 to 20 yards. I'm more accurate with it at 10 yards (33 feet) than with standard iron sites. I like how low profile it is and also is very bright in all conditions. Never needs to replace batteries. I might buy one or 2 more for some of my other pistols.

The red doesn’t hold illumination well, even after priming the sight with light. Daytime performance exactly like promo photos, night ehh but you can still see it, if you have a weapon light like I do the light from the weapon will illuminate the sight like daytime, so a little workaround if needed

As a firearms instructor/trainer I find this sight as an excellent alternative to a RDS. It simply replaces the rear iron sight and gives the shooter a similar sight picture. It covers both day light and low light situations. No need to replace the holster, no concerns about batteries. Minor adjustments to grip and sight alinement/sight picture.Just ran a instructor school and a third of the class jumped on their phone and place order for the sight after using my Glock with the sight.

After much excitement about this sight, I got it in and installed easily. Just took a little filing and slipped right in with the tool I bought to do this with. I took it to the range today anxious to use, It ended up dropping my shots where I wasn’t even hitting the paper! After fiddling around and wasting ammo finally was able to hit the targets by aiming at the top of the paper, not the target….. the paper! In all fairness I was hitting my mark consistently by aiming 18” to 20” high. But still that is too far off for me to forgive. I went home and removed it, went back to the range to confirm my original sights and was right on my mark again thank goodness. I rely on reviews to buy things and I figure I’m not the only one that does this. Great idea but epic expensive failure, too bad.

I've tried lots of sights from standard notch and post, TFO's, Big Dots and even have an RMR on a Glock 19. I'm not ready to throw everything else away after two range trips, but this very well could be game changing to the industry over the next few years.No batteries or electronics to worry about, no giant red dot screen interfering with concealed carry, and you get a brilliant easy to use sight picture. Bit of a learning curve to use after thousands of repetitions with standard sights, but basically you see a green dot, and when center a bright circle appears, put the dot on the target and press. Works in bright sunlight to dark just fine due to tritium in the tubes.I will say if you have need for MAJOR power reading glasses these will not help as much as a true red dot sight like an RMR will. I wear 1.25 reading glasses for more comfortable reading and computer work but can get by without if needed, and these sights work fine for me without correction or "Cheater" safety glasses.Very happy I bought this sight, a great compromise between $100 quality hi visibility notch and post sights, and full on $500+ with milling quality red dots that bring thier own issues.

I bought this in hopes of installing it on my SIG M17. Unfortunately it does not fit...Doesn't fit the p250, p365 or the M17. No adapter plates available either
