XS Suppressor Height Sights – Glock 19 Follow Up

by Pete

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.

    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....

    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.

      @MrEllis 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.
