I bought these because of the rave reviews by James Yeager (look for his YouTube channel) and the fact that I wanted night sights because to my thinking bad guys attack in the dark (be it home invasion at night or dark places in public) most of the time. Yeager runs force on force training classes and claims that students constantly report that they hate the XS sights until they have to use them while being shot at (with sim rounds) and then suddenly they make sense. My experience echos this.

Installation is a breeze. Just take your time and think about what you're doing before you go putting red loctite anywhere you shouldn't, and it can be done in 30 minutes with just the included tools. Easy.

The tritium inserts are barely visible in daylight but when it's dark they're extremely easy to pick up.

I HATE these sights for range shooting. I'd call myself a far above average pistol shooter when it comes to accuracy. If I'm taking my time and have finer sights (such as stock Glock sights), I can put rounds through the same hole all day long. The XS sights make this much much harder because the front sight is about 25MOA wide at arms length (so it covers a 25" circle at 100 yards or a 2.5" circle at 10 yards). There's no precision shooting when your sight covers that much target area.

While this is really annoying for target shooting and I can understand why foolish people give these negative reviews, you have to remember what they're for. These are fighting sights. They aren't meant for shooting tight groups slowly. They're meant for putting all your rounds in a torso quickly, should you ever need to defend yourself.

XS Big Dot sights are designed for fast, intuitive target acquisition in all light conditions. And that's what they do - very well. They are not designed for accurate target shooting. They are not designed for small targets. XS sights are designed to be used on a fighting pistol, one you will defend your life with, and at relatively close distances (50 feet or less).
Most of the negative reviews I've seen about these sights were by people who didn't do their research before buying and thought they'd be great for shooting 1" groups. I have not had problems getting all rounds on a 12 inch target at 30 feet with relatively rapid fire. That is what they are made for.
Again, these sights are for Concealed Carry handguns and duty weapons. They are excellent for that purpose, but if you are looking for cheap night sights or putting them on a gun for a different purpose, look elsewhere.

I've gone thru a 'wheelgun phase' for the past year or so....and mostly happy - love the .357 round for it's potency...figured I could live with the limited capacity in the trade. Recently I got the good fortune to attend another gun club's match as a visitor and compete in a great defensive simulator match that involved having to shoot 25 steel targets in 6 locations you moved between on the line. It was fantastic, but just looking at the course and watching...I knew I couldn't use my wheelgun.

I went to one of my Glocks (I chose the 26 I actually shoot it better, being able to put the pinky under the grip gives me a nice base) and I used the mags from my 19 as back up mags - so only 1 mag change was necessary.

I used the "stock sights" as that is all I had ever used....and I did OK...but I found the winner (and my friend that invited me to compete) used the XS Big Dot sights.

When it was over...I asked my friend to let me try his Glock with the XS sights and it was AMAZING to me the difference! Time to Target was easily cut in half - maybe more. That big white dot (or at night - both front and back XS sights glow in the dark) is SO easy to put on target quickly! It's just that simple - move the big dot to the target and squeeze - and my hit ratio to center of mass went WAY up too. Super easy to do - and while i am not interested in punching tiny holes in a 1" space at 50 yards...I did notice that I could easy ring more steel out to 50 yards with these sights as I was becoming more adapted to the 'big white dot' out front.

There is very little reason (that's practical) to me to worry about shooting a defensive pistol at great distances...it is fun, but that's about it...

These sights ( both front and rear contain tritium,and are made with steel ) come with virtually everything needed to mount them on the Glock of choice, with the correct installation taking less than 20 minutes! After the required drying time for the included locktite, the sights prove themselves and their value through lightning fast hits at combat distances with the greatest of ease. Once your vision picks up the HUGE front dot, simply place it on the target and squeeze. Yes, it is that simple - and accurate. Took 100 rounds of .40 S&W to the range to sight in my offduty Glock 27, but only had to use 40, as each round was true to point of aim and impact. Have also installed these on a Glock 30, but have not yet sighted in same, although a similar finding is expected and will not be surprised thereafter. Also, these are night sights of the dot and post variety, highly visible in reduced light and darkness. Hits are also easily made under these conditions, quickly and accurately.
XS sights are referred to as accessories, but the improvements they provide can be looked upon as necessities. Just my opinion, and I carry 24/7, and have been for over 27 years.
