Engineered from rugged alloy steel with precision CNC machining, these sights fit an extensive range of Glock models, including MOS variants. Featuring a highly visible Big Dot front sight paired with a V-notch rear, they enable fast target acquisition and reliable shot placement in high-stress, close-quarters scenarios. Proudly made in Texas, these combat-ready sights are chemically resistant and built to endure years of demanding use. ## Description Product description The Big Dot allows you to quickly find your ā€œiā€ sight without distractions in stressful situations, making it easier to acquire, align, and aim at targets in any lighting condition. It also helps the aim of those with aging eyes and deteriorating vision. Photoluminescent Glow Dot with the tritium center on the front sight and the tritium bar on the rear sight absorb ambient light, allowing for self-illumination 24/7 for up to 10 years, ensuring high contrast in bright environments and brightness in low light. All XS night sights are CNC machined from steel bar stock in Texas, ensuring they are protected from drops, racking off barricades, and will hold up for years. Our sights are chemically resistant to acetone-based cleaning solutions and ultrasonic cleaners. The Glow Dot is gun powder residue-resistant and can be easily wiped off with a cloth. Review: Great sights, but misunderstood. - I've installed and used 18 sets of these on various Glock pistols over time. Once you install and use them correctly they are great, the key word here is 'correctly'. Most of the reviews I read here and elsewhere with people exhibiting difficulties can be linked to not installing correctly or not using them correctly. First, these are not 'precision' sights. So if you are expecting to put all rounds in a 1 inch group at say 25 yards 100% of the time then these are not 'accurate' enough for you. These are in a class of sights known as 'combat sights' (close engagement) which are basically used to put rounds on target very quickly under stress (e.g. self defense) in a Minute Of Bad Guy (MOBG) scenario for shots that stop the threat from continuing, for up to about 15 yards and quick 'close quarters' engagement. So, for example, in the MOBG usage shots landing in a 6-8 inch area center mass area, or in the bad guy in the chest area, are 'accurate' for these sights even if its not a tight precise group of, say 1 inch another person might consider 'precision'. Second, that being said, the aiming method given by xs is the correct aiming method for these sights. No, the center dot in the big dot is not what is used to dot the 'I' the bottom of the big dot is used to dot the 'I' in all ranges used. Its only when greater than ~25 yards is the top of the big dot used as the aiming point instead of the center if the big dot. I routinely put rounds in 8 inch circles at 50 yards with these sights with all rounds in the circle as I intended even though these sights are really for close quarters engagement type of work, so if a distance like this is your thing then you can also do it with these sights. This is 'accurate' but for another person it may not be accurate in terms of precision if that person intended a 1 inch group for all rounds fired. Herein lies the ambiguity of the term 'accurate' for these sights. They are not intended to be 'precision' accurate but rather MOBG accurate as a combat sight (described above). If you want to try the sights out and not yet sure if you will like them...do not use the red locktite instead use blue locktite, try them out for a couple hundreds rounds. If you don't like them then they will be much easier to remove. However, if you do like them and plan to keep them on the gun then remove them and completely remove all blue locktite and go through the install procedure again but use the red locktite this time. Another thing, filing. If you absolutely do not need to file then don't. A small amount of resistance may be noticed on some Glock dovetails, this does not always mean you need to file so tapping it into position is correct. In short if the sight can be drifted or pushed into position do not file. Only if you encounter excessive resistance in getting the sight in position should you file and then only if the sight will absolutely not move into position no matter what you do without filing. DO NOT PUT LOCKTITE ON THE SET SCREWS. Its not necessary but if you do then use only the barest hint of blue locktite on the set screw threads only and not red locktite. The front sight, follow the xs sights instructions. They take about 15 minutes at the most to install, its not difficult. Follow the XS sights instructions, take your time. However, if you encounter difficulty on install contact XS. I have had to use these sights In actual life threatening deadly force defense... they are lifesavers when the stress and movement of that eyeblink moment in time arrives. Review: Great product, great site picture. - Easy install. Comes with all the items you need to successfully install it. Locktite, front sight tool. I was impressed. Now to the sights. Iā€™m over 40 and use glasses and even without them on I can see the large front dot. I love the sight picture. I really recommend it. The only criticism is that in total darkness the tritium is present but much harder to see. Still, Iā€™m talking about near pitch black. Great product. I will be buying them again. ## Features - Fits: Glock 17,19,19X,22,23,24,26,27,34,35,45,49 models. Tritium front & tritium rear set.
