TFB Review: Fiber Optic XS Sights for Glocks - Worth $60 to Upgrade?

Why a design that is over 40 years old has so deeply and indelibly penetrated the firearms market is a bit perplexing. Everywhere you turn at the gun range, it is Glocks as far as the eye can see. Gaston Glock obviously was onto something because here we are 42 years later deploying them for military, law enforcement, competition, self-defense, and general tomfoolery at the range purposes. One of the hallmark downsides to a factory Glock pistol though are their sights. They are plastic… a dull white color… and prone to breaking if you’re doing one of those YouTube brutality tests for some internet clout.

So, what are your options for upgrading the factory sights on your newly acquired Glock - whether it is brand new or previously owned? Well, the gamut runs from the expensive to the simplistic, and XS Sights offers the whole gamut. Today, we are going to take a gander at their modest yet mindfully-designed fiber optic sight sets for Glocks. Is the $60 upgrade to fiber optic worth it? Stay tuned, rapscallions, as we venture down the Glock rabbit hole.

The stark contrast of a semi-glowing, fiber optic front sight paired with an all-black rear is meant to catch your gaze quickly for fast target engagements. Similar to what red dots look to accomplish except this XS Sights offering requires no batteries, no 21st century tech, or the loss of multiple Benjamins from your wallet.

A Word from XS Sights on their Fiber Optic Sights for Glocks

While these sights are simplistic in their appearance, that does not mean they are low on features and attributes. XS Sights expands upon all of the secret sauce that they poured into the making of these sights in their press release statement below:

“Upgrade your competition or training pistol with Glock Fiber Optic Sights from XS Sights! Featuring a precision CNC machined, serrated rear sight and our steel front sight with a fiber optic insert, the XS Fiber Optic sights were designed for fast sight acquisition, precision sight alignment, and easy installation.

Our .215” tall, .125” wide front sight is big enough to be visible yet narrow enough for extreme precision. The .060” diameter fiber optic gather’s light and fluoresces for extreme visibility in the bright light conditions common to practicing at ranges and competition shooting events. 

The .145” wide notch and crisp, defined edges on the rear sight allows for good visibility around the front sight blade for fast acquisition and precision alignment. The serrated rear face prevents glare to increase the ease of front sight focus.”

Elevator Pitch - Why Upgrade?

So, where does the rubber meet the road with these sights? What is the value proposition, and why should you invest your hard-earned dollars into a simple upgrade like this? Well, glad you asked because XS Sights has an answer for that as well:

“Looking to customize your Glock? Sights are the perfect upgrade. Factory sights on Glock handguns have a few issues, and XS Sights has you covered! The first common problem with factory sights is the plastic construction, causing them to malfunction by breaking or moving after use. XS Sights are constructed from steel, ensuring they are durable and will hold up to the wear and tear of training. The second major issue with factory sights is the sight picture itself being difficult to see in different scenarios. Our fiber optic sights address this issue by including a vibrant front sight that is hard to miss in bright light settings. These are just a few of the many reasons to make your first Glock upgrade, an upgrade to XS sights!”

• Unscrew the current Plastic Front Sight
• Put a small dollop of Loctite on the Screw for your new XS Sights Front Sight

Additionally, if you are someone with vision impairments and see red better than green, or vice versa, XS Sights has you covered with multiple color selections.

Final Thoughts - XS Sights Fiber Optic Sights for Glocks

So, what are my final thoughts on the XS Sights Fiber Optic Sights for Glocks?... Is it worth the coin they’re asking?... I would say: yes.
