Glock 19

One of the benefits of the Glock 19 design is the different variations of that platform available from reputable manufacturers. One such example is the FX19 Patriot from Faxon Firearms.

The FX19 Patriot is essentially a Glock 19 with all the customizations included that one would normally add to a stock Glock 19.

The benefit here is that you get an already upgraded Glock 19 platform out of the box at roughly the same price if you were to buy a stock Glock 19 and all these upgrades separately.

Having all that done and tested by Faxon Firearms is worth the price point all day long.

Best Glock Upgrades

Often regarded as the best firearms right from the box, Glock handguns not only enjoy widespread acclaim but also offers an extensive range of accessories and aftermarket upgrades that surpass those of Barbie and GI Joe combined.

Let’s take a look at some of the best upgrades available for Gaston Glock’s revolutionary polymer creation.


Equipping a handgun with a suppressor can be likened to driving a muscle car with your foot to the floor, delivering a shooting experience that feels like it was always meant to be.

Unfortunately, stock sights often fall short in height, making it essential to choose a sight that stands taller for improved visibility.

While you’re at it, why not consider incorporating night sight capability?

Night Fision, a well-established Tritium license holder in the United States, possesses profound knowledge and experience in handling Tritium. Their Tritium night sights are renowned for their exceptional advancements within the handgun market. What distinguishes Night Fision Tritium night sights from their competitors?

Primarily, Night Fision employs a ballistic polymer cup, setting them apart from numerous other companies that solely utilize a painted ring or small cap. This ballistic polymer cup is crafted from the same resilient material found in bulletproof glass and is treated with a fluorescent pigment.

Within the confines of the cup resides a specifically tailored Tritium vial, exhibiting a gas pressure that surpasses any other night sight by 30%, thereby producing a more radiant luminescence.

Lastly, the combination of the ballistic polymer cup and the custom Tritium vial is seamlessly integrated into a 4140 metal body, which is subsequently coated with a black nitride finish.

One could even assume that these sights would withstand an apocalypse.


If you’re considering equipping your Glock with a suppressor or compensator, it’s time to acquire a threaded barrel. Faxon offers Titanium Nitride (TiN) PVD-coated stainless steel barrels, featuring traditional rifling and tighter tolerances than the OEM standard.

While discreet black options are available, there are moments when you may desire a touch of style, such as Faxon’s eye-catching chameleon barrel.

Whether you’re an avid participant in professional shooting competitions or simply aiming to improve your shot-to-shot split times during practice, a compensator can undeniably provide valuable assistance.

Faxon’s EXOS-513, with a name reminiscent of a game from the Halo series, exhibits an aesthetic appeal that perfectly matches its functionality. Constructed from black anodized 6061 aluminum, the EXOS-513 effectively redirects muzzle blast upward and outward, significantly diminishing muzzle rise.

The tremendous gains in target acquisition speed achievable with a high-quality compensator are truly remarkable and must be experienced firsthand. It’s no wonder that professional competition shooters who have the option to use a compensator opt for one due to the distinct advantages it offers.


The battle between the Glock 19 and the Glock 43X can be fierce at times, highlighting their respective strengths and differences.

However, it’s important to consider the Faxon FX19 Patriot as a worthy contender in this comparison. With its custom-cut slide, optimized grip, and enhanced sights, the Patriot offers a concealed-carry firearm option that demands attention. The inclusion of a match-grade barrel and compatibility with popular optics further solidify its appeal.

When making your decision, take into account the Faxon FX19 Patriot alongside the Glock 19 and the Glock 43X. Each firearm brings its own unique advantages, ensuring there is a reliable and capable option for every individual’s preferences and needs.
