P320C versus the Glock 19 – Battle of the Compact Kings

It’s head-to-head Glock vs. Sig. Is there a winner?


The compact pistol market is absolutely massive. Compact pistols rule because they are the perfect size for a variety of applications. If you want one pistol for home defense, concealed carry, and all other handgun tasks, then the compact pistol is the way to go. On the current market, the Glock 19 has long been the king of compact firearms. However, a challenger has arrived, and it’s the P320C. Today we are going to do a little Glock 19 versus SIG P320C and see if there is a new king of compact handguns.

Ergonomics – A Subjective P320C versus Glock 19 Category

Ergonomics are largely a subjective experience. As long as nothing ergonomically creates a dangerous situation, then it’s largely subjective. As a big-handed goon, it’s easy for me to say the controls of both guns are largely the same. The magazine release is easy to reach, and my thumb pins down both the slide locks. Not much different.

I do prefer the straighter grip of the P320C, but the guns are largely identical when it comes to objective data.

Although this is subjective, I prefer the P320C ergonomically. The grip is more comfortable. However, because it’s my opinion, I won’t be awarding any points in this section of the Glock 19 versus P320C contest.


Here is where we see the P320C really pull ahead in this little Glock 19 versus SIG P320C showdown. The SIG benefits from having a smoother trigger pull and better sights as well. Glock clings to these crappy plastic sights, but SIG utilizes much better sights, and when combined with the better trigger, it’s seemingly more accurate.

At least in my hands. The Glock 19 is a very capable weapon and is very accurate. The P320C pulls ahead just slightly, and out of the box, I was able to hit gongs at 50 yards without issue with the P320C. With the Glock 19, I didn’t experience the same consistent accuracy.


Does modularity matter? In 2021 it matters enough that the Army named their handgun contest the Modular Handgun Contest. SIG won that contest, and it won this section of our Glock 19 versus P320C debate. The Glock 19 has a massive aftermarket, but the P320C offers a different degree of modularity.

That modularity includes being able to move the serialized Fire Control Unit to a variety of different frames. Some made by SIG, some made by others. You can change triggers, sights, and optics and even convert the gun to various calibers should you so choose. Heck, I’m surprised I don’t have a way to attach M-LOK accessories. The aftermarket doesn’t replace true modularity.


Here is where the Glock 19 shines through and scores its own point in this Glock 19 versus SIG P320C competition. It’s not that the P320C is unreliable by any means. The Glock 19 wins because it’s one of the most proven firearms on the market. It’s been carried, issued, and tested for decades now. It’s a proven platform, and it’s a crazy reliable platform.

The Glock 19 wins hands down in the reliability department.

Where The Glock 19 Shines

The Glock 19 comes out swinging with more triggers, holsters, sights, magazines, and more available for it than any other compact pistol on the market. It’s been such a flag bearer for so long that it dominates the market by sheer numbers alone. It’s a reliable pistol that’s proven, it’s accurate, capable, and certainly earned its place as the top dog.

Where the P320C Shines

SIG is hungry, and it shows. The P320C features a revolutionary design that opens it up to modularity. SIG has tossed their back into supporting the P320C and escalates it to the top of the pile. It comes with better sights, a better trigger and provides shooters with a multitude of options that Glock simply can’t touch.

Who Wins?

To me, the P320C is a better gun. It comes with more for the money, and the price point between the two pistols is nil. The Glock 19 is a great gun and always has been, and the downside is that Glock has grown complacent. They don’t seem interested in advancing their design or even giving their firearms half-decent sights. Are you under-armed with a Glock 19? Heck no, but if I was at the gun store, SIG is getting my money.
