LIKE THE GLOCK NEEDS ANY INTRODUCTION…

 

The Glock 19, a time-tested favorite in the firearms realm, is a compact, lightweight, semi-automatic pistol revered for its reliability and durability. The simplicity and ease of use inherent in the Glock 19 have made it a preferred choice among both law enforcement and civilian users.

Its compact stature makes it an ideal candidate for concealed carry, while its robust design assures reliable performance under varying conditions. Over the years, the Glock 19 has built a reputation based on consistent performance and the trust it has garnered from its users.

 

… BUT THE SIG SAUER P320 IS NO SLOUCH

 

In contrast, the Sig P320, a versatile player in the market, is a modular semi-automatic pistol offering a level of adaptability seldom found in other firearms. The P320 is an evolved version of the Sig Sauer P250, employing a striker-fired mechanism instead of a double-action-only hammer system.

One of the hallmark features of the P320 is its modularity, enabling users to effortlessly switch from one caliber to another. This feature, coupled with its modern ergonomics and reliable performance, has propelled the P320 to popularity among both civilian and professional users. The versatility and adaptability of the P320 have helped it carve a significant niche in the market.

You gotta admit that both the Glock 19 and the Sig P320 bring unique features to the table in the firearms industry. The Glock 19 is lauded for its reliability and simplicity, while the Sig P320 is admired for its versatility and modularity.

As you can see based on the main specs and size comparison, the Glock 19 appears to be a better choice when it comes to concealability. On the other hand, the SIG P320 is a slightly more affordable option and while slightly heavier, it can be a more versatile option. But more on that in a sec.

 

GLOCK 19: COMPACT FRAME FOR EFFORTLESS HANDLING

 

The Glock 19 is a compact, lightweight, semi-automatic pistol known for its easy handling. It boasts an overall length of 7.36 inches, a slide length of 6.85 inches, and a width of 1.26 inches. The barrel length of the Glock 19 is 4.02 inches, contributing to its compact nature and ease of use.

Regarding weight, the Glock 19 is quite light, weighing 21.16 oz without a magazine, 23.63 oz with an empty magazine, and 30.16 oz with a loaded magazine. This lightweight design renders the Glock 19 ideal for concealed carry and easy handling, even under high-pressure circumstances.

 

SIG P320: VERSATILITY IN A HEAVIER FRAME

 

On the other hand, the Sig P320, although slightly heavier, showcases a versatile design. It has an overall length of 8.0 inches, a height of 5.6 inches, and a width of 1.3 inches. The barrel length of the P320 is 5 inches, slightly longer than that of the Glock 19.

In terms of weight, the Sig P320 is heavier than the Glock 19, weighing 29.4 oz unloaded. Despite its weight, the P320 is revered for its versatility and adaptability, thanks to its modular design. This design enables users to easily convert from one caliber to another, making the P320 a versatile option for both civilian and professional users.

In a nutshell, the Glock 19 is more compact and lightweight, facilitating easy handling and concealed carry; the Sig P320, although heavier, offers a versatile and adaptable design, allowing for easy caliber conversion.

 

SIG P320 VS G19 ERGONOMICS

 

GLOCK 19: A COMFORTABLE GRIP FOR MANY

 

Let’s face it: the Glock 19 is famous for its comfortable feel and sound ergonomics. The grip angle of the Glock 19 is designed for shooting under stressful conditions, making it effective in defensive situations.

The Glock 19 Gen 5 offers the option to add extra backstraps to increase the grip size, providing a plethora of options for customizing the grip to fit your hand. Despite some criticisms about the aggressiveness of the slide serrations, the ergonomics of the Glock 19 are generally well-received.

The elimination of finger grooves in the Gen 5 model, along with the addition of an ambidextrous slide stop, has enhanced the fit and appeal of the Glock 19.

 

SIG P320: A DISTINCTIVE GRIP

 

The Sig P320, however, has what I would call a “distinctive grip.” Some users have expressed dissatisfaction with the original grip, favoring the X-Series and Wilson grips for their superior ergonomics.

The removable fire control group of the P320 allows for an easy transformation from full-size to subcompact, adding to its versatility. However, some users have found the bottom of the Wilson grip backstrap to press uncomfortably into the bottom of their palm.

 

PERFORMANCE: ASSESSING ACCURACY, RECOIL, AND RELIABILITY

 

GLOCK 19: RELIABLE PERFORMANCE OVER TIME

 

The Glock 19 is reputed for its consistent performance. It is a solid performer across the board, easy to use, and stays on target. The Glock 19 Gen 5 has received praise for having the best out-of-the-box trigger from Glock.

In terms of accuracy, the Glock 19's new Marksman barrel, featuring a new rifling pattern, is designed to enhance accuracy and consistency. The Glock 19 is also known for its reliability, with one friend of mine telling me it might be the most reliable handgun they own, having run a dozen ammo types through it and over a thousand rounds between cleanings.

 

SIG P320: NOTABLE ACCURACY AND RELIABILITY

 

No shrinking violet, the Sig P320 is also recognized for its impressive accuracy and reliability. I’ve found it consistently hit targets from varying distances, from 5 yards to 25. Despite some issues with steel-cased ammo, the P320 has proven to me to be a reliable performer.

The construction, fit, and finish of the P320 are on par with other SIG models, and it has held up remarkably well under rigorous use. The trigger of the P320 is often touted as "the finest trigger ever put in a striker-fired handgun," making it a pleasure to shoot.

Despite a few malfunctions I had in 2,000 rounds, I consider the P320 reliable enough for carry.

 

GLOCK 19 VS SIG P320 AFTERMARKET SUPPORT

 

GLOCK 19: A PLETHORA OF AFTERMARKET CHOICES

 

This is an arena where the Glock 19 shines, rendering it a very popular choice among customization aficionados. Support for the Glock 19 in the aftermarket is one of its major advantages, offering a broad range of parts, upgrades, and accessories. From custom Glock slides, extended slide releases, Glock sights, and optics to triggers and mag wells, the options are vast.

 

G19: SLIDE INTO IT

 

For instance, upgrading the slide is one of the most significant enhancements you can make to improve aesthetics, with many aftermarket slides featuring lightning cuts and improved serration designs.

Home defense gun owners might incorporate lights or lasers to their handguns for improved accuracy, while competition shooters might modify their barrel or other components for enhanced shooting performance or reduced carry weight. Concealed carriers might alter their weapon for increased ease of concealment, extended clip capacity, or ease of racking the slide.

 

SIG P320: EMERGING SUPPORT IN THE MARKET

 

I have seen that the Sig Sauer P320 is gradually gaining a foothold in the aftermarket scene, with an increasing number of upgrades available. The P320 is one of the most modular firearms in the world, with the capability to swap calibers, frame sizes, and more.

This versatility, paired with its adoption by various police forces and the United States military, continues to drive a burgeoning aftermarket.

Some of the best upgrades for the Sig Sauer P320 include the Sig Sauer AXG & X Series Grip Modules, Mirzon Grip Module, Faxon Barrel, and Griffin Armament Micro Carry Comp. Other notable upgrades include high-visibility designs coupled with the low-light utility of tritium, Trijicon HD Night Sights, and the Zev Technologies Z320 XFull Octane Slide, which offers ergonomic and practical enhancements over factory components.

The bottom line: both the Glock 19 and the Sig P320 offer a wealth of aftermarket support, allowing users to tailor their firearms to their specific needs and preferences. Whether you're seeking improved performance, enhanced aesthetics, or increased versatility, both these firearms offer a range of options to choose from.

 

CONCLUSION: GLOCK 19 VS SIG P320

 

The Glock 19 is hailed for its reliability, simplicity, and extensive aftermarket support. Its compact, lightweight design makes it easy to handle, rendering it a popular choice for concealed carry. If a proven track record and a plethora of customization options appeal to you, the Glock 19 might be the right choice for you.

Conversely, the Sig P320 shines with its unique grip, impressive accuracy, and modular design. Though slightly heavier than the Glock 19, its versatility and growing aftermarket support position it as a strong contender. If you value adaptability and a smooth trigger pull, the Sig P320 might be your best bet.
