Overview of the Glock 43X MOS and Sig Sauer P365 X Macro

The Glock 43X MOS and Sig Sauer P365 X Macro are both 9mm handguns designed for concealed carry. Each pistol offers features that appeal to different users, from magazine capacity to grip texture and size.

Brief History and Evolution

The Glock 43X MOS is part of the Glock 43 line, which was first launched in 2015 to meet demand for slim, single-stack carry pistols. The MOS version added a modular optics system, allowing users to mount red dot sights easily. This feature boosts both aiming speed and versatility.

Sig Sauer introduced the P365 in 2018, changing expectations for concealed carry pistols with its high-capacity, micro-compact frame. The X Macro builds on this platform, offering a longer grip and accessory rail. This evolution improved control and comfort for a wide range of shooters.

Both pistols have adapted to competitive market trends, focusing on reliability, ease of use, and adaptability. These updates continuously meet modern concealed carry needs.

Positioning in the Concealed Carry Market

The Glock 43X MOS is popular for its slim profile and user-friendly controls. It appeals to users who value simplicity, Glock’s reputation for reliability, and easy concealment even with optics installed. Its widespread availability makes parts, holsters, and accessories easy to find.

The Sig Sauer P365 X Macro targets users seeking higher capacity within a compact footprint. The pistol features an aggressive grip texture, modularity, and the ability to accept optics out of the box. Many appreciate the improved shootability offered by the longer grip and increased round count.

These handguns compete directly as leading options for concealed carry. Their market positioning shows a focus on blending comfort with capacity, while maintaining compact dimensions.

Key Specifications Comparison

The Glock 43X MOS is lighter and slightly slimmer, making it easier for many users to conceal. In contrast, the P365 X Macro provides a significantly higher magazine capacity and a more customizable grip, though it comes with added weight and grip texture.

Both pistols are compatible with popular concealed carry holsters and can be fitted with optics. Magazine options and aftermarket support are strong for both models, giving users plenty of ways to personalize each handgun.

Concealability and Ergonomics

Both the Glock 43X MOS and Sig Sauer P365 X Macro are built for concealed carry, but key differences in their size, weight, and ergonomics affect how they handle and feel day-to-day. Choosing the right model often comes down to these factors and how each fits the shooter's needs.

Size, Weight, and Concealment

The Glock 43X MOS is known for its slim design and low weight. With an unloaded weight of around 18.7 ounces and a 1.1-inch width, it slides into most holsters easily and avoids printing under clothing. The barrel length is 3.41 inches, helping with deep concealment.

The Sig Sauer P365 X Macro, while still slim, is slightly larger. The X Macro model weighs about 21.5 ounces unloaded and has a longer 3.7-inch barrel. Its width is 1.1 inches, keeping it close to the 43X MOS in terms of how easily it hides, but the grip length is a bit longer, which can sometimes make it less hidden for some body types.

The shorter grip of the Glock 43X MOS provides an edge for those who prioritize concealment. The longer grip of the P365 X Macro, however, allows for a higher magazine capacity, so there is a trade-off between concealment and firepower. The P365 X Macro is still considered very concealable, but people with smaller frames may notice the extra size.

Grip Comfort and Controls

Grip comfort is a big selling point for both pistols. The Glock 43X MOS offers a straightforward, textured grip with a modest beavertail, giving shooters reasonable control without being bulky. Many find the 43X MOS fits nicely in the hand, but it does have a shorter grip than the X Macro, which may affect comfort for those with larger hands.

On the other hand, the Sig P365 X Macro features a longer, slightly more contoured grip that accommodates most hand sizes. The beavertail is more pronounced, improving comfort and helping manage recoil. Shooters also benefit from the X Macro’s forward and rear slide serrations that make racking the slide simple.

Both pistols lack manual safety features and rely instead on passive safety features. The controls on both models—slide stop and magazine release—are easy to reach and use. The lightweight frames and well-placed controls enhance overall ergonomics, but those who prefer a manual safety will have to look elsewhere.

Both options deliver for shooters who value a comfortable, secure grip in a lightweight and concealable package. The X Macro stands out for larger hands and longer shooting sessions, while the 43X MOS’s slim grip is more suitable for smaller hands or tighter concealment needs.

Optics and Sighting Systems

Both the Glock 43X MOS and Sig Sauer P365 X Macro allow users to use red dot optics for faster aiming. Sighting options affect accuracy, personal preference, and how quickly a shooter can get on target.

Red Dot Compatibility

The Glock 43X MOS is cut at the factory for micro-sized red dot optics. It uses the Shield RMSc footprint, which is compatible with popular choices like the Holosun 507K and the Sig RomeoZero Elite. This makes it easy for owners to add a red dot without expensive custom work.

The Sig Sauer P365 X Macro is also optics-ready from the factory. It uses the same RMSc footprint found on many carry pistols. Users can install several types of red dot sights, including the Sig RomeoZero series and other similar optics. Both pistols allow a red dot to be mounted low enough to co-witness with iron sights in most cases, making them versatile for different needs.

Stock Sights Versus Aftermarket Options

The Glock 43X MOS comes standard with basic polymer sights. Many shooters upgrade to aftermarket sights, such as night sights or fiber optic models, for better visibility. Since Glock sights are widely available and easy to change out, there are plenty of options.

The Sig Sauer P365 X Macro often features XRAY3 day/night sights as standard, offering improved brightness out of the box. Still, some may prefer different styles or sight colors and can replace them with aftermarket sets made for the P365 line. Both pistols have strong aftermarket support, letting users customize their sight picture to fit their shooting style and environment.

Performance and Reliability

Both the Glock 43X MOS and Sig Sauer P365 X Macro are known for being dependable choices for concealed carry. Their performance in key areas can make a real difference in safety and confidence for those who carry every day.

Accuracy and Precision

The Glock 43X MOS is built with a 3.41-inch barrel and fixed sights. Its slightly longer sight radius can help shooters line up accurate shots at close to medium distances. It also fits a wide range of hands, which can support consistent aim.

The Sig Sauer P365 X Macro, on the other hand, features a 3.7-inch barrel and comes standard with XRAY3 Day/Night sights, which can make aiming easier in low light. The grip shape and undercut trigger guard help shooters get a stable hold, allowing for fast follow-up shots and tighter groups. In side-by-side tests, the P365 X Macro is often praised for its shootability.

Both pistols are designed to be precise with proper technique, but the P365 X Macro's features often give it a slight edge for users who value improved sights and small comfort details.

Reliability in Real-World Scenarios

Reliability is critical in a self-defense handgun. Both pistols use a striker-fired system, which is known for simple operation and few moving parts.

The Glock 43X MOS has a reputation for running smoothly even after hundreds of rounds. Shooters often report minimal malfunctions when using quality ammunition. Its durable build handles regular practice and everyday carry demands. Reports of jams or stoppages are rare, which is a core reason for Glock's trusted name in handguns.

The Sig Sauer P365 X Macro has shown strong reliability during extended range sessions. Owners value that the gun keeps going despite rapid fire and varied conditions. The P365 series' durability over years of testing is well documented, and the X Macro carries forward the positive reputation for dependable function under stress. For those placing reliability as their top priority, many compare the performance directly, with opinions split, but both models are praised for dependability, as noted in this discussion.

Trigger Characteristics

Both the Glock 43X MOS and the Sig Sauer P365 X Macro feature striker-fired triggers, which offer consistent pull from the first to the last shot.

The 43X MOS trigger is described as clean and predictable. Its pull weight is around 5.5 pounds, and its tactile, audible reset makes it easy to know when the pistol is ready to fire again. Many users find the trigger's characteristics familiar from other Glock models, aiding muscle memory.

The P365 X Macro has a slightly lighter trigger pull, at about 4.5-5 pounds. Its break is crisp, and the reset is short. Shooters often praise the smoothness and quick reset, which helps deliver accurate, fast shots. The comfortable trigger feel, paired with the grip ergonomics, can enhance user confidence during both practice and high-stress situations.

In direct comparisons, neither trigger is known for being the lightest or most competition-focused, but each is well-suited for everyday carry and quick, accurate shooting. For a detailed breakdown, see how both options stack up in real-world reviews such as this side-by-side test.

Capacity and Caliber Considerations

Both the Glock 43X MOS and Sig Sauer P365 X Macro use 9mm, but their approach to magazine capacity and ammo flexibility makes a difference for daily carry. Capacity and ammunition availability are key points for anyone wanting a reliable option for self-defense or range use.

Magazine Capacity

The Glock 43X MOS features a standard magazine holding 10 rounds. While slim and easy to conceal, this capacity can be limiting for users who want more shots before they have to reload.

The Sig Sauer P365 X Macro stands out with a 17+1-round magazine in a similar slim profile. This larger capacity gives a significant advantage to people who value having extra rounds on hand. It ranks among the highest standard capacities for concealed carry in 2025.

Because its grip is only slightly larger, Sig’s extra capacity doesn’t make the gun much more complicated to conceal than the Glock. Some shooters may also use aftermarket magazines in the 43X that can increase their capacity, but this isn’t standard from the factory.

Caliber and Ammunition Availability

Both pistols fire 9mm ammunition, a popular and widely available choice for self-defense. The 9mm’s balance of stopping power, manageable recoil, and affordable price makes it practical for most users.

Ammunition for 9mm is easy to find in stores and online, so keeping either handgun supplied won’t be a challenge. Neither gun is available in other calibers from the factory, so buyers looking for something other than 9mm should consider different models.

Choosing between them comes down to personal preference for gun feel and the importance of magazine capacity, since both handle the same round in similar-sized frames.

Features and Customization Options

Both the Glock 43X MOS and the Sig Sauer P365 X Macro stand out with slim designs and solid reputations. Their built-in features and wide range of upgrades make them top choices for concealed carry.

Factory Features

The Glock 43X MOS offers a factory-milled slide that makes mounting red dot optics simple. It uses a slim single-stack magazine with a 10-round capacity. The 43X MOS has basic Glock sights, a smooth trigger, and a short rail for small lights or lasers.

The Sig Sauer P365 X Macro comes standard with a higher 17-round magazine and a built-in compensator to help reduce muzzle flip. It also features a factory optic cut, upgraded sights, and a more aggressive grip texture.
