If you’ve recently purchased or browsed for your next gun, you may have considered Sig vs. GLOCK. The two manufacturers are powerhouses in the industry, each boasting a rich history and unique design that many are drawn toward. So, what makes the two different? How good of a brand is Sig Sauer? Who made GLOCK? It is important, especially for gun enthusiasts and those looking to make their next big purchase, that you understand the difference between the two.

In this blog, we’ll dive into the histories of each brand and how they developed their styles, hopefully arming you with the knowledge to make an informed decision when selecting your next firearm.

A History of Sig vs. GLOCK

Let’s start by answering: Who made GLOCK? GLOCK Ges.m.b.H was founded in 1963 by Gaston Glock, an Austrian engineer and businessman. In 1986, the company committed to the American market by opening its U.S. headquarters in Smyrna, Georgia. Initially focusing on non-firearm products like machine gun casings and knives, GLOCK began producing semi-automatic pistols in the early 1980s as the needs of the Austrian military changed. 

GLOCK’s lightweight polymer frame and internal safety system revolutionized the industry, making the brand a favorite for law enforcement, military agencies, and civilians over time. Today, GLOCK’s reliability, durability, and ease of use keep consumers returning en masse.

Continuing in the Sig vs. GLOCK debate, the Sig Sauer we know today was created in the 1970s when the Swiss Schweizerische Industrie Gesellschaft (SIG) merged with German firearms manufacturer J.P. Sauer & Sohn. The brand, for good reason, is one of the most well-respected firearms companies in the world. Its history goes back to the 1800s when Friedrich Peyer im Hof, Heinrich Moser, and Conrad Neher set out to develop a state-of-the-art rifle that would be used by the Swiss Army. Today, the company employs over 1,200 and, like GLOCK, is a popular choice for law enforcement and military units. For decades, the Navy SEALs used the popular P226 as their sidearm of choice before switching to the G19 in 2016.

Sig Sauer vs. GLOCK: A Comparison

Now that we’ve discussed the history, let’s talk performance. While GLOCK and Sig guns are both designed for reliability and precision, there are many factors that differentiate the two, including weight and ergonomics.

Design

GLOCK guns are renowned for their simplicity and durability. In fact, models are made from an average of just 35 parts. The minimalistic design makes GLOCKs easier to maintain and may help reduce malfunctions. Sig, on the other hand, prioritizes craftsmanship and user experience. It’s why many say that Sig wins the looks battle every time. If you are a fan of aesthetics, Sig may be the best choice for you when analyzing Sig vs. GLOCK.

Aftermarket Customization

While the two brands are different in many ways, aftermarket customization options are an area where both give users an extensive selection. Glock and Sig pistols have sizeable aftermarket support, making it easier to find and install custom parts and accessories. This support allows their owners to personalize their firearms to better suit their preferences and needs.

Materials and Construction

For many users, construction plays a major factor in the Sig vs. GLOCK debate. Sig guns are often praised for their solid feel and durability. Fans of the metal feel tend to gravitate towards Sig firearms while those who prefer the lighter weight, polymer finish go for GLOCKs. Important to note: Although the Sig is technically heavier than the GLOCK, The National Interest says that the difference is too small for the average gun user to truly notice.

Trigger Systems

A major difference between Sigs vs. GLOCKs is their trigger system. GLOCK primarily uses a striker-fire system, which means that the trigger pull is consistent in weight and feel from shot to shot. This consistency is appreciated by many shooters, particularly in high-stress situations where predictability is essential.

Sig, on the other hand, makes models that rely on a hammer-fire system. Hammer-fired pistols tend to have a longer, heavier trigger pull in double-action mode, followed by a shorter, lighter pull in single-action mode. This can offer more versatility for shooters but may require additional training to master.

Safety Mechanisms

Safety is another major factor in the Sig Sauer vs. GLOCK comparison. One of GLOCK’s major selling points is its SAFE ACTION System, which is designed to give shooters the freedom to concentrate solely on their shooting performance. Including trigger, firing pin, and dropping safety, GLOCK’s goal is to prevent accidental discharges while still allowing for intuitive performance.

For Sig, pistols often come with external manual safeties or decocking levers, depending on the model. Some shooters prefer the added control and safety provided by these features. Overall, both brands continue to show a high commitment to safety.

FAQs

Is the SIG better than the Glock?

The Sig vs. GLOCK debate generally boils down to a user’s preference. With this in mind, there really isn’t an outright winner. Those who prefer craftsmanship and hammer-fire systems, for example, would potentially be better off with a Sig.

Do Navy SEALs use Glock or SIG?

For over 30 years, the Navy SEALs used Sig. In 2016, however, they switched over to the G19.
