The Glock 19 has long been a benchmark in the handgun world. Its combination of reliability, versatility, and simplicity has made it a top choice for military, law enforcement, and civilians alike. However, the firearms market is constantly evolving, and in 2018, SIG Sauer shook things up with the launch of the P365—a compact pistol that promised to challenge the status quo. But could the P365 really dethrone the Glock 19?

The Legendary Glock 19
The Glock 19, introduced in 1988, has built a legacy as one of the most versatile firearms available. It’s large enough to serve as a duty weapon, yet compact enough to conceal. With its 15-round magazine capacity, minimalistic design, and reputation for reliability, it’s been the go-to for millions of users across the globe.
Glock’s simple design, with very few moving parts and the absence of external safeties, has made it the favorite of those who want a pistol that just works—no matter the conditions. It’s easy to maintain and has an extensive aftermarket of upgrades and accessories, from custom slides to enhanced triggers, giving shooters almost unlimited customization options.
The Glock 43 and 48: Prepping the Market
Before SIG Sauer introduced the P365 in 2018, Glock had already begun catering to the concealed carry market with the Glock 43 and Glock 48 in 2015.
The Glock 43, with its slim profile and 6-round magazine, was Glock’s answer to the growing demand for more concealable pistols. Its single-stack magazine made it slim enough for deep concealment, but some felt its capacity was too limited compared to other options on the market.
The Glock 48, with a 10-round capacity, provided a longer grip and slide while maintaining a slim profile. This model was designed to offer a balance between concealability and shootability, directly competing with compact pistols of the time.
At the time of their release, these models were well-received, but it wasn’t until SIG Sauer introduced the P365 that the concealed carry landscape truly shifted.
The Disruption: SIG Sauer P365
When SIG introduced the P365 in 2018, it was an industry game-changer. With a 10+1 round capacity in a package smaller than the Glock 43 and slimmer than the Glock 19, it made waves immediately. How did SIG manage it? By redesigning the magazine, allowing more rounds to fit without increasing the gun’s size significantly.
For those focused on concealed carry, the P365 offered the perfect balance between size and capacity. It was small enough to easily conceal, yet provided enough rounds to give shooters confidence. As SIG expanded the line with models like the P365 XL and P365X, they offered even more versatility with extended grips, optics-ready slides, and enhanced ergonomics.
The P365 SAS, with its anti-snag design, further emphasized SIG’s commitment to the concealed carry market, offering features that were optimized for deep concealment.
Is the Glock 19 Threatened by the P365?
While the P365 has undoubtedly carved out a niche, it’s unlikely to completely overshadow the Glock 19. The Glock 19 offers a level of versatility and reliability that few pistols can match. Its 15-round capacity, larger grip, and longer sight radius make it a better all-around pistol for duty use, home defense, and even competition shooting.
Moreover, Glock has not rested on its laurels. With the Glock 43X and Glock 48, which offer 10+1 capacity and compatibility with aftermarket 15-round magazines, Glock continues to compete in the slimline market. These models have helped Glock remain a major player in the concealed carry space, even with the growing popularity of the P365.
Conclusion: A Growing Landscape of Options
Rather than one pistol putting the other out of business, what we’re seeing is an evolution of options. The P365 excels as a compact, high-capacity carry pistol, while the Glock 19 remains a versatile workhorse for all types of use. Additionally, Glock’s own lineup of slimline pistols, like the 43 and 48, offers serious competition to the P365 in the micro-compact category.
Ultimately, the emergence of the P365 has pushed Glock to innovate further, which benefits everyone. Shooters now have a wider range of reliable, high-capacity pistols to choose from, depending on their specific needs.
The competition between Glock and SIG Sauer is far from over—and that’s great news for anyone looking for the perfect carry gun.
