Orange Front Sight : Sports & Outdoors Review: Long time user with no complaints. - Love this product. I’ve used them on several pistols now. They are made from quality material. Holding up to years of daily use. The bid dot up front acts like a red dot sight. Allowing for quick acquisition and target focus. Very helpful with follow on shots as well with the lower rear sight not obscuring the front sight or target. The tritium insert work amazing at night. They glow bright and are easily lined up under the darkest conditions. Installation is a breeze. With the supplied tools making it no hassle. desertcart delivered these and I had them mounted in under 30min. Fittment was perfect and aligned perfectly first try. The value compared to other sights is comparable. The appearance is what you would expect of this product. XS big dots are on the bigger side of sights but still fit within the standard sizes. Doesn’t really affect the appearance of your gun. Great product highly recommend for defensive shooting. 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. ## Features - Fits: Glock 17,19,19X,22,23,24,26,27,34,35,45,49 models.

Comes with all the items you need to successfully install it. Locktite, front sight tool. I was impressed. Now to the sights. I’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, I’m talking about near pitch black. Great product. I will be buying them again. ## Frequently Bought Together - XS Sights DXT2 Big Dot Tritium Night Sights. Tritium Front and Rear set.
