Sig P365 vs Glock 43x

SIG P365 vs. Glock 43X – Brandon’s Concealed Carry Showdown

At Gas & Brass Armory in Brandon, FL, one of the most frequent questions we hear is: “Which is better for everyday carry, the SIG P365 or the Glock 43X?”

It’s a fair question. Both pistols are highly respected, slim, and designed for concealed carry. Each has its own strengths, and the “better” choice really comes down to what matters most to you as a shooter. In this guide, we’ll break down the differences in size, capacity, ergonomics, features, and everyday carry comfort so you can decide which one fits your needs best.

Why These Two Pistols Get Compared So Often

The SIG P365 redefined what a micro-compact pistol could be. Before it, most slim carry pistols were limited in capacity—often 6+1 or 7+1 rounds. The P365 shook things up by offering double-digit capacity in a truly pocket-friendly size. That balance of small footprint and big firepower made it an instant hit.

The Glock 43X is Glock’s answer to the demand for a slim, easily concealable pistol that still feels like a “full grip” handgun. It blends Glock’s legendary reliability with a slightly longer grip than the original Glock 43, giving shooters more control while keeping the gun thin.

In short: the P365 wowed the market with innovation, while the 43X delivered Glock’s proven consistency in a modern slimline package.

Size and Concealability

If concealment is your number-one priority, the SIG P365 usually has the edge. It’s shorter in height, with a more compact profile that disappears easily under a T-shirt. Many customers at our Brandon gun shop choose the P365 because it’s the easiest pistol in this class to hide without printing.

The Glock 43X, while still very slim, has a taller grip. That extra length makes it slightly harder to conceal for some people, though others find the larger grip worth it for shooting comfort.

Local takeaway: In Florida’s hot weather, where light clothing is common, the smaller footprint of the P365 often feels like a smarter choice.

Magazine Capacity

Capacity is one of the biggest differences people notice.

• SIG P365: Ships with a 10-round mag, and you can easily upgrade to 12- or even 15-round factory magazines.
• Glock 43X: Comes with 10-round mags. Aftermarket companies make higher-capacity magazines, but many concealed carriers prefer sticking with OEM mags for peace of mind.

For a pistol this small, the P365’s capacity is a major selling point. If you value more rounds without more bulk, SIG wins this round.

Ergonomics and Comfort

A firearm has to feel right in your hand—and this is where personal preference matters most.

The SIG P365 is praised for its contoured grip, textured surface, and undercut trigger guard that allows a higher grip. Many shooters comment that the P365 “shoots like a bigger gun” despite its compact size.

The Glock 43X has the familiar Glock feel—straightforward, blocky to some, but comfortable and consistent to others. For shooters who already own other Glocks, the 43X often feels natural, making training and transitions easier.

Tip from our Brandon store team: Try dry-firing both side by side. The difference in grip angle and trigger pull will quickly tell you which one your hands prefer.

Features and Variants

The P365 line has exploded with options:

• P365 XL: slightly larger frame and barrel for better shootability.
• P365X: blends the XL grip with the standard slide.
• Optics-ready models: ready for micro red dots.
• Spectre Comp: integrated compensator for reduced muzzle flip.

Glock keeps things simpler. The 43X MOS is optics-ready, but otherwise Glock tends to stick with a “less is more” approach.

If you like having multiple versions and customization options, SIG gives you more ways to grow within the same platform.

Everyday Carry in Florida

Carrying in Florida means you want something lightweight, easy to conceal, and reliable in heat and humidity.

• P365: Many Floridians love the balance of small size and big capacity. It’s easy to carry in a waistband holster, and even pocket carry is possible with the right setup.
• 43X: The larger grip gives confidence when drawing quickly and shooting at the range, but it’s a little less forgiving under lighter clothing.

Both are excellent concealed carry choices—you just need to decide if you’d rather prioritize capacity or grip size.

Local Opinions: What Customers Say at Gas & Brass Armory

We’ve had countless customers in Brandon and Tampa put both pistols in their hands. Here’s what we often hear:

• P365 buyers say: “It disappears when I carry it,” and “I love that I can run a 15-round mag as backup.”
• 43X buyers say: “It feels more natural in my hand,” and “I’ve always trusted Glock.”

Neither group is wrong—it comes down to comfort, confidence, and what you value most.

Which One Should You Choose?

  • Maximum capacity in the smallest possible package.
