Sig Sauer P365

Sig Sauer P365

The award-winning Sig Sauer P365 micro-compact pistol is hands-down one of the most commonly used firearms for concealed carry and with good reason.

This striker-fired gun is built with a lightweight stainless steel frame and a carbon steel barrel coated with a durable Nitron finish. The Sig is chambered in 9mm Luger and is rated for +P ammunition. It comes standard with two 10-round flush magazines, though an optional 12- or 15-round extended magazine is available for those who want a greater capacity.

The popular handgun is built with Sig’s XRAY3 day and night sights, a 3-dot tritium system designed to work well in both high- and low-light conditions.

Lightweight and easy to conceal, the Sig Sauer P365 is highly-rated and an excellent choice for everyday carry, home defense, or whatever you need it for.

Glock 43X

Glock 43x

Carrying the reputation for excellence associated with the Glock brand, the 43X does not disappoint.

The striker-fired pistol is designed for comfort and concealability, complete with a built-in beaver tail and a subcompact-slim slide for a versatile grip.

The Glock 43X’s compact Slimline frame is finished with a scratch- and corrosion-resistant nDLC coating, designed to protect the pistol from both the elements and normal wear and tear.

This popular handgun is also built with a short trigger distance, a reversible magazine catch, and a match-grade Glock Marksman Barrel with enhanced rifling to improve accuracy.

Chambered in 9x19mm, the Glock 43X’s lightweight, slim design and high-tech features make it a great, versatile option for concealed carry.

Size and Capacity

The Glock 43X and the Sig P365 are roughly the same size, with a few key differences. The 43X is built slightly larger than its Sig Sauer counterpart, measuring just around an inch longer and taller than the P365 with an ever so slightly longer barrel and wider frame. The Sig is a bit heavier than the Glock, however, weighing just under an ounce and a half more.

The 43X stands 5.04” tall, 6.5” long, and 1.10” wide. It has a barrel length of 3.41” and weighs 16.4 oz, while the P365 is a bit heavier at 17.8 oz. with a barrel length of only 3.1”. The Sig also has a smaller frame than the Glock, measuring 4.3” tall, 5.8” long, and 1.06” wide.

Both the Sig micro-compact and the Glock sub-compact pistols are designed with concealed carry in mind and come standard with a nice 10+1 capacity. Sig does offer the option to increase its capacity with either a 12- or 15-round extended magazine, making it a great choice for those who want to carry more rounds. While Glock does not manufacture an extended magazine for the 43X, higher-capacity magazines can be purchased through third-party sellers for this model if desired.

Which one wins in terms of size depends on whether you’re looking for a smaller frame or a lighter pistol, though the Sig Sauer is a better choice if you want the option of an increased capacity.

The Sig P365 is built with a micro-compact black stainless steel frame and finish and a polymer grip. While the Sig’s frame works perfectly well as-is, it can be replaced with the longer Sig P365 XL frame if you need a little extra grip length.

The Glock 43X is built with a compact polymer Slimline frame. It features a built-in beavertail and a compact, comfortable grip that fits a variety of users.

Slide and Barrel

When it comes to the slide and barrel, the Glock takes the cake. It’s black, subcompact-slim slide is built with a durable nDLC finish designed to protect the gun from scratches and corrosion. It also comes equipped with the Glock Marksman Barrel, which is designed with enhanced barrel rifling for better accuracy.

The P365, on the other hand, has a stainless steel slide with a protective Nitron finish and a carbon steel barrel. Both pistols feature front and rear slide serrations.

It’s no contest: the Sig P365 comes out on top when it comes to sights.

The P365 comes standard with Sig’s X-RAY3 day and night sights, a 3-dot tritium system designed for a natural target acquisition in any lighting condition. The X-RAY3 has a 4.9” sight radius and is crafted with an oversized chemical resistant fluorescent polymer front dot. The tritium sights are surrounded by steel to protect them from recoil, cleaning solvents, and the elements.

The 43X comes equipped with Glock’s standard plastic sights, which have just over 5” line of sight.

Though the Glock doesn’t come with the same quality of sights out of the box as the Sig does, both pistols are designed so they can easily be upgraded with sights of your choice.


Though neither base-model pistol comes optics ready, the Glock 43X has an edge over the Sig P365 as it does come in an optics-ready variation.

The Glock 43X MOS (modular optic system) is, for all intents and purposes, the exact same as the Glock 43X base model. The difference is that it comes with a mounting rail for accessories and features slide cuts compatible with certain micro-optics.

So, if you’re interested in utilizing optics or accessories, the 43X will provide you with more options than the Sig Sauer P365.


Concealed Carry Glock 43x


When it comes to safety, the Sig may come out ahead.

While neither gun comes standard with a manual safety, the P365 is now available in a version that does offer a manual safety option. The Glock’s only safety feature is it’s Safe Action Trigger System, which is comprised of three independent mechanical safeties that disengage as the trigger is pulled and reengage as it is released.

The Safe Action System does provide protection if the pistol is dropped, though it doesn’t offer the same protection as the Sig’s manual safety.


The Glock 43X is designed with a 2.64” trigger distance and a 5.39 lb trigger pull, while the Sig P365’s curved trigger has a clean, striker fired trigger pull weight of around 6 lbs.

Which is Right for Me?

The right gun for you all comes down to your personal preferences. If you’re looking for a pistol with a higher round capacity, the Sig Sauer P365 may be the best choice for you. If you want the option to add optics or accessories, the Glock 43X is a better pick.

So, think about what you need out of a concealed carry gun. Now that you have a better understanding about the differences, strengths, and weaknesses of the two firearms, you can make the choice that’s right for you.
