It was about a year ago I reviewed the then new F8 sights from XS, you can read that review by following this link.  For the record, those sights are still on that Glock 19 and have still not given any trouble. It was a couple of months ago the new XS DXT2 Big Dot night sights showed up. They were easily installed on my Glock 28 and we took some time to see what was what. I also thought it was a good idea to compare them to the F8 sights as well.

The Big Dot is 0.188″ with a photoluminescent orange dot adding contrast to the center night sight.

T The rear sight is a gentle U shape with a white line and tritium insert. This set up is a “dot the i” sight alignment. This makes for a quick flash sight picture that would work well for a defensive pistol.

The front sight is small enough to keep from snagging during the draw.

The rear sight is small to help stop snags but has enough of a ledge to use to rack the slide, if need be.

The XS DXT2 sights did not interfere with holstering in my Alien Gear holster.

The rear sight is drove in the Glock dovetail and secured by two set screws.


Comparing the F8 sights to the DXT2

The DXT2 sights are great for a quick sight picture on your defensive pistol using the “dot the i” sight picture but are precise enough to put accurate rounds downrange.

  • Tritium Powered Front & Rear Sight – Glows in low light to aid in sight alignment

I spent much of my youth involved with firearms and felt the call early on to the United States Marine Corps, following in my father's and his brother's footsteps. Just after high school I enlisted and felt most at home on the rifle range, where I qualified expert with several firearms and spent some time as a rifle coach to my fellow Marines. After being honorably discharged I continued teaching firearm safety, rifle and pistol marksmanship, and began teaching metallic cartridge reloading. In the late 1990s I became a life member to the National Rifle Association and worked with the Friends of the NRA. Around that time my father and I became involved with IDPA and competed together up until he passed away. I began reviewing firearms for publications in the mid 2000s and have been fortunate to make many friends in the industry. Continuing to improve my firearms skills and knowledge is a never ending journey in which we should all be committed. I am also credited as weapons master on a few independent films.

One thought on “XS DXT2 Big Dot night sights.”
  1. I bought some Ameriglo’s that are similar for 2 of my Glocks. (supposedly FBI spec) That orange ring is right out there. The U-notch in the sights you show is probably better for accuracy. Mine have the squared off Glock style rear. The orange is not visible at night unless you have a flashlight then it just POPS!

    Good article, thanks!
