The SIG P365, developed by SIG Sauer Inc., is a micro-compact semi-auto pistol, considered by many the greatest modern concealed carry handgun. And there’s a couple of reasons for this. Not only is the gun very compact (just like its classification suggests), it also offers high capacity, impeccable accuracy and considerable firepower. If matched with a well-fitting SIG Sauer P365 holster, this pistol also becomes an ultimate choice for everyday concealed carry.

The GLOCK 43, introduced by Glock Ges.m.b.H., has been one of the most popular sub-compact handguns of the last decade, there’s no doubt about it. It’s pretty much a slimline version of the well-known Glock 26, offering similar operation, slightly lower capacity, but substantially more compactness. Just like the SIG, if the G43 is paired up with a custom-fitted Glock 43 holster, the pistol instantly becomes one of the best carry guns currently available on the market.

Size matters

source: Handgun Hero

The SIG P365 is one of the most compact pistols ever produced. The pistol is 5.8’’ long and mere 1’’ wide, featuring a 3.1’’ long barrel. While this comes at the cost of firepower when compared to the full-sized handguns, it definitely results in super easy concealment. After all, isn’t that what everyone is looking for these days?

The Glock 43 is very similar in its dimensions to the SIG, but it’s still one bit larger. The overall length of the pistol is 6.26’’, featuring a longer 3.41’’ barrel. The gun is a bit thicker than its competitor as it’s only 1.06’’ thick. This means the pistol is even more ideal for both outside and inside the waistband carry, although the difference is not SIGnificant at all.

On top of their compactness, both pistols are also ultra lightweight when not fully loaded. The SIG weighs 17.8oz, while the Glock weighs 17.95oz. This means that no matter which of the two you decide to go for, you won’t even notice you’re carrying them.

Result of the size battle? - TIE

The magazine and capacity

The SIG Sauer P365 was designed with one particular thing in mind - high capacity. And that’s exactly what SIG Sauer Inc. delivered. The SIG undoubtedly offers the highest capacity among sub-compact handguns (alright, the Hellcat beats it, but only by a bit). The SIG’s flush magazine comes with 10 rounds of ammo, which is 4 more than the Glock. Moreover, upon the pistol’s release, SIG introduced an extended 12 rounds magazine with a pinky extension. But SIG didn’t stop there as later on they amazed the world with another extension, this time a breath-taking 15 rounds magazine. And if you’re wondering how the heck it’s possible to stuff 10 rounds into such a small handgun, the answer is simple - a double stack magazine!

In comparison with the SIG, the Glock 43 only comes with a 6 rounds flush magazine. As the GLOCK is famous for a vast number of aftermarket upgrades, it’s obvious you can extend the basic capacity. However, as the Glock’s magazine is a single stack, the best you can get is a 10 round extended magazine.

The winner of this battle is clear… the SIG


Sig P365 vs Glock 43 Recoil

Navigating the terrain of handgun choice, the discussion on recoil between the Sig P365 and Glock 43 is pivotal for potential buyers. Among the firearm community, it's broadly reported that the Sig P365 exhibits a more manageable recoil. This characteristic often translates to enhanced shooting stability and control, permitting more precise follow-up shots, which is a significant advantage for both novice and experienced shooters alike.On the flip side, the Glock 43, although acknowledged for its reliability and widespread use, is noted to have a relatively higher recoil. This facet might pose a challenge for some shooters in maintaining accuracy during rapid-fire situations. While exact measurements in foot-pound force and joules are not standardized, the consensus leans towards the Sig P365 for those prioritizing lower recoil in their firearm selection.

The winner of this battle… the SIG

Glock 43 vs Sig P365 Accuracy

The P365 is a highly accurate pistol, mainly thanks to the SIG Sauer XRay3 Night Sights. The front sight boasts high day and night visibility. It’s pretty much a high visibility green ring around a tritium vial. The rear sight consists of two tritium vials and it is serrated in order to reduce glare, which is an ideal solution for brighter environments. And although there were some issues with the sights shortly after the pistol’s initial release, SIG Sauer were quick to fix these problems and the P365 can now compete even with full-sized handguns when it comes to accuracy and target acquisition.

The Glock 43 comes with the front and rear factory sights. In front, there’s a white dot and in the rear the pistol features a white square U shaped sight. As Glock is famous for its aftermarket products, you’ll see many shooters equipped with modified sights systems.

When it comes to how well the pistols perform in range during dynamic shooting, I’d say the Glock is one step further. Upon putting in a number of consecutive rounds, you’ll definitely notice the Glock’s hits are more predictable, while those of SIG are a bit more dispersed across the target. This, however, by no means says anything bad about the P365 and I wouldn’t pick the Glock 43 over its rival based solely on this factor.

A winner of this stand-off, although not by much, is … the GLOCK

Caliber and firing mechanism

It will be of no surprise to you that both pistols are chambered in the 9mm cartridge. The 9mm definitely is the most popular (and affordable) caliber when it comes to everyday carry guns. It might not boast such firepower as the .45 ACP, .40 S&W, or the 10mm, but it definitely does the trick. For personal-defense and a bit of plinking fun, this caliber is more than ideal.

The G43 and P365 are also identical in the firing mechanism, as both pistols are striker-fired. Now what does that mean? Simply put, a striker-fired pistol engages a round via a striker hitting the firing pin. The firing mechanism is built into the pistol and fully covered by the pistol’s slide. Such mechanism results in slightly lower firepower, especially when compared to hammer-fired pistols. However, it also means that both the SIG and Glock are composed of fewer parts, which SIGnificantly reduces the threat of any hardware malfunctions.

I’d say this battle ends in a … TIE
