Sig Sauer P365 vs. Glock 43

Given a choice between the Sig Sauer P365 vs. Glock 43, which of the two weapons is best for concealed carry? Even though they aren’t target pistols, both enjoy a considerable amount of popularity with firearm enthusiasts, so if you’re thinking about picking up one of them, this article should help with that decision. Let’s get into it!

Sig Sauer P365 vs. Glock 43 – Side by Side Comparison

At a glance, the Sig P365 and the Glock 43 weigh about the same when empty, though the Glock 43 is the longest gun. However, the P365 offers more capacity, as it comes with a double-stack magazine compared to the 43’s single-stack mag.

Moreover, Sig Sauer’s firearm offers better sights for low-light conditions and comes with safety. However, the Glock 43’s trigger comes with a safety lever, and I prefer its slide action to the P365’s.

Dimensions and Weight

Sig Sauer P365

Both the Sig Sauer P365 and the Glock 43 weigh 16.5 oz when carried without a magazine. Additionally, these concealed carry pistols share identical grip widths of 1.02 inches. However, you’ll find differences in the two guns’ overall length, height, barrel length, and thickness.

The Sig P365 is the shorter of the two guns length-wise, being 5.8-inches long compared to the Glock 43’s 6.2-inch length. Meanwhile, the Glock 43 is slightly shorter than the Sig P365, standing 4.5-inches high vs. the P365’s 4.3-inch height.

Finally, the Sig P365’s barrel is narrower and shorter than the Glock 43’s, being 3.1-inches long and an inch wide compared to the 43’s 3.39-inch length and 1.02-inch barrel width.

Both firearms feature textured grips. However, with the Sig P365, it’s easier to position your fingers, thumb, and index finger to get a solid grip on the handgun. We have the undercut and recess grooves on the back and sides of the gun’s grip to thank for that.

Moreover, even though the Sig P365’s grip is completely texturized, it isn’t so aggressive as to make daily carry (i.e., when worn as an everyday carry gun with a holster against bare skin) uncomfortable.

Meanwhile, you can swap the P365’s magazine release for an aftermarket one, which is fortunate as it isn’t ambidextrous. The P365’s slide lock and slide release work as expected, with the slide release providing excellent traction.

As for the Glock 43, its grip doesn’t have the undercut and recesses you’ll find on the P365’s grip. I think that contributes to it being less comfortable to hold, and if your hands get sweaty easily, you may need to use pistol grips or grip tape to keep the gun from slipping out.


The Sig P365 comes with two double-stack magazines, one of which includes a finger extension. Meanwhile, Glock’s single-stack magazine firearm comes with a pair of polymer magazines (one with a pinky extension).

Regarding mag capacity, the Sig Sauer P365 offers more, featuring a ten-round capacity compared to the Glock 43’s six. Of course, magazine extensions are possible with both guns, but Sig Sauer has Glock beat in that department too.

Since the Sig P365 is a double-stack magazine pocket carry pistol, you can extend its mag capacity to a whopping 15 rounds (when you purchase the +2 extended mag). In comparison, aftermarket upgrades for Glock magazines only extend the 43’s capacity to 10 rounds (the same capacity as the P365 without aftermarket extensions).


Sig Sauer’s pistol features steel tritium front and rear sights that offer decent shooting accuracy when used in low-light conditions. The rear sight consists of two tritium vials, while the front features a green ring. So even though the P365’s front sight isn’t the brightest during the day, I think the gun’s night sights are decent.

In comparison, Glock’s plastic sights leave a lot to be desired. They aren’t useful at night, meaning you’ll have to add higher-quality ones that the P365 saves you money buying. Some Glock pistols feature decent sights, but unfortunately, the 43 isn’t one of them.


Even though the P365’s trigger doesn’t have a safety lever, the omission doesn’t make the trigger feel uncomfortable when pulled. On the contrary, some people argue that the P365’s trigger feels smoother, going as far as to say they’re better than the factory triggers on Glocks (which might have to be replaced with aftermarket triggers).

On the other hand, similar to hammer-fired pistols, the Glock 43’s trigger does have a safety lever. However, you might need to hold off on celebrating if you have long fingers, as the safety lever doesn’t go fully into the trigger face. Besides that, Glock’s pistol’s trigger pull is robust and audible compared to the P365’s.


Both guns feature serrations on their slides to make racking them easier. However, the serrations on the P365 are more aggressive than those on the Glock 43, while the serrations on the 43 are higher than the ones on the Sig P365.

If I could pick which slide was easier to operate, I’d go with Glock 43. Mind you, that’s a personal preference, as the slides on both firearms are so easy to operate that there’s no clear winner in this category.


You can order an ambidextrous thumb safety with your Sig P365, which you can place at the gun’s rear. This is an excellent option, as it lowers the chances of an accidental discharge.

As for the Glock 43, it doesn’t have external safety, meaning you’ll have to be very careful when carrying and handling this gun.


The price difference between the two guns isn’t too big, though, at face value, Sig Sauer’s firearm is slightly more expensive than Glock’s. However, as mentioned above, when you consider that you’re going to have to upgrade the sights on Glock’s gun, you save more money going with the P365.

Sig Sauer P365 vs. Glock 43 – What’ll It Be?

It’s up to you to decide which of these two pistols suits your needs, and if you’re looking for a compact gun that’s easy to conceal, you can’t go wrong with either one. Also, their size will make shooters with small hands feel right at home handling these guns.
