XS Suppressor Height Sights – Glock 19 Follow Up

Put me solidly in the “shoot through the can” group of suppressed pistol shooters. A group that swears they are just as accurate with standard-height sights even with an obscured sight picture. And it’s true, it’s perfectly doable – lining up your sights is 90% of the battle when placing shots on target. But it doesn’t have to be the only way to shoot suppressed.

So, searching for a better way, I literally jumped at the chance to do a follow-up review to Phil’s XS Suppressor Height Sight 1911 installation and review a few weeks ago. And as my first set of dedicated tall sights, I am very impressed.

Since Phil covered proper installation and setup of the XS system, let’s skip all the way to the good stuff: Shooting. It’s almost turkey season, so I picked out a 12″ steel turkey target at 15 yards for testing.


Before we get to the suppressor-specific discussions, while I consider this an unbiased review, I have to admit that I have been a longtime fan of the XS Big Dot lineup. Between the large and bright front sight and the “Dot-The-I” sight picture, the whole system is one of my favorites. After easily nailing that turkey from 15 yards, I moved out to the 50 and hit that target nine out of ten times. And while I’d like to credit my sharp-shooter, world-class, super-precision shooting techniques (that’s sarcasm folks) the XS Big Dot makes those shots seem pretty easy.

After following the instructions on the XS web page and YouTube videos (love the mustache) and the details in Phil’s article, installation of my set was a breeze. My Glock 19 is a third generation with a pressed-in front sight so I was a little nervous that I was going to mess something up during the removal process. But a couple of generous taps with a brass punch and the front sight popped without issue. Using the included polymer punch and little penetrating oil, my rear sight slid out with only a few taps.

The XS rear sight slid into place without the need for any modification or force – a fact I was thankful for since i was worried my layer of Cerakote would require light sanding or filing to the sight base dovetail.

How much higher are the XS sights from stock? In an unscientific measurement, the rear sights were slightly less than 0.2″ higher than the OEM.

And in a nod to consistency, the front XS sight is also just lightly less than 0.2″ taller than the original post.

I used two suppressors two test the sight picture of the XS system: a SilencerCo Octane 45 HD with an outer diameter (OD) of 1.37″ and a “Form 1” suppressor I built myself with an OD of 1.5″.

With the Octane, the sight picture is perfect and unobscured. Both the rear XS sight and the front XS Big Dot rise above the the suppressor body to give a clean view of the target.

Even using my Form 1 can with the larger OD, the mount/booster assembly (made by Liberty Suppressors for their Mystic 9mm silencer) barely blocks any of the XS sight picture. Getting quick, well placed shots was much smoother than the standard factory option. I intentionally built a shorter but wider can, so I was surprised that the taller XS sights cleared my setup at all.

The only downsides I can see to taller sights are that holster choices may be somewhat limited and the taller sights may be more prone to snags on clothing or gear. Although my test Glock 19 isn’t a carry gun, it did fit snugly into my Raven Concealment holster.

XS Sight Systems is an excellent company that stands behind their products. Even if you were like me and saw no need for taller sights when shooting suppressed, it’s well worth your time to give the XS Suppressor Height Sight system a shot. Pun intended.

    G19 3rd Gen have pressed in sights? When in the world did that happen? I’ve got a G19 3rd Gen sitting in front of me disassembled, and it’s got a screw-type sight from the factory. Perhaps I just got lucky?

    In any case, I’ve been looking around at different models of high sights, and finally finding that these have both the right height and tritium, I’m certainly going in the right direction. The rest I came across seemed to be either higher or tritium, and these appear to be lacking the three dot tritium I like the best.

    Still, perhaps I’ll give it a try, the rear bar “dot” seems like it might work as well, and it is available in tritium at least.

    Also, that mustache is wearing glasses.

    • I especially like these because unlike most these have smooth edges and don’t stand so darn high. I like stacking the dot over the bar. It’s fast and easy to see.

      • PK

        Well, perhaps I’ll have to give it a try. You never know, maybe it’ll end up being my new favorite style. I don’t think I’ve ever really used anything but the three dot setup.

    • Pete M

      It’s weird. Some 3rd gens are pressed in.

      I really like the big dot.

      • PK

        Two recommendations for the big dot sight. Alright, I’ll give them a try. Worst case, someone gets a lightly used set of sights as a gift!

  • Drunk Possum

    On these sights, is it a standard “6 o’clock” hold for hitting your target? I’m not too familiar with the “Dot the I” style sights.

    • Pete M

      From XS:

      “A better Point of Aim (POA) / Point of Impact (POI) system. When your eye is making that shift in focus it will lock onto the brightest thing first. The brightest part of the dot is the center. Placing that over the desired point of impact is a natural reaction. **From 15 yards on in our POA/POI is center of the dot.** As the range increases and you have more time for a refined sight picture we take advantage of your pistols ballistics. Bullets start out below line of sight and the barrel angle is such that they rise to line of sight. **By having the under 15 yards POA/POI at the center of our dot then as the range increases to 25 yards the bullets flight will take it to near the top edge of the front sight.** Now you have the best of both worlds. A stress sight picture that is quick and easy to find and index on the target and a more precise POA/POI when you need it at longer ranges.”

        Thanks, very informative. Go figure, right from the company’s website. Way to use the Internet, Possum.

        • Pete M

          In your defense, ‘drunk possum’ 😉

            Nothing more productive than drunken Internet surfing right??

    I agree with the author on many points in this piece. First, many look through a red dot sight as you would a scope. I look at the target and then bring the RDS into my field of view as one would have done the original ACOG. I believe Pete is talking about doing the same thing with a can mounted and standard height sights.

    Second, XS sights are a top product. They are different and many just can’t get used to them but they do work. My experience is with the standard height but otherwise same sights. Offhand I can hit a paper plate with a G19 at 100 yards. I hold the sites in such a way that you have a white dot, then your front dot sitting directly below that and touching and then the “I” directly below the front sight but not touching since the tritium vial “breaks” the line or prevents it from making contact when sighting the pistol.

    A complaint you often hear is that they are too big. Hold the front dot under the target at ranges past about 15 yards. How do you think long range shooters can accurately shoot a group when they are shooting past the range at which their front sight or reticle obscures the target?

    Another complaint you hear is that they are inaccurate. See my comment above about the paper plate.

    • Pete M

      All good points and I agree.

      It takes a bit to get used to the feeling of a 2x front sight.

      But after a mag or two, you have that “moment of clarity”.

  • Michael Lubrecht

    One small hint on installin sights (or other accessories, for that matter). Always file or sand the cheapest part! If the sights don’t fit the dovetail, just carefully file or sand the base of the dovetail until they fit. You may need to look at the sides as well, to make sure you’re not removing too much metal from any one place. But, don’t file on the slide….

  • MrEllis

    That stippling, I’m having flashbacks to the post with abused guns. Oh, crap, idea, yeah, feel it coming. Popcorn!

    I’ll take care of them if you can’t.

    • Pete M

      Hahahah + 10 internet points for you.

      I actually was going to include my own gun in that piece just as a “beauty is in the eye of the beholder” message.

      Anyway. Flame on. Free punches. Etc.

        Hey, if it works, it ain’t stupid!

    • sliversimpson

      A company called “Day 2 Friearms” is doing grip enhancements for polymer guns, in which they cover the grip with some sort of resin that is shaped to make the pistol more comfortable to shoot. I held one and like it pretty well. The Glock still felt substantial. It’s hard to say without practical use, but it seemed like it might hold up.
