What is a Single Stack Pistol? Why is it often preferred?

A single stack pistol is one that uses a single stack magazine. As the name suggests, cartridges are only stacked one on top of each other, rather than side-by-side in an alternating fashion.

Single Stack vs Double Stack Magazine

The most obvious benefit of pistols designed to be used with single stack magazines is their width. Naturally, single stacks are thinner than double stacks. For instance, when comparing the Glock 26 (double stack) to the Glock 43 (single stack), the overall width of the Glock 43 is 0.2 inches thinner (1.26 in vs 1.06 in). This may not sound like a lot, but the near 16% decrease in width goes a long way in being able to comfortably concealed carry the Glock 43.

The decrease in overall width and slide width, combined with single stack pistols carrying less ammunition, also makes them a fair bit lighter than double stack pistols. Again comparing the Glock 26 (25.75 oz with loaded magazine) to the Glock 43 (20.64 oz with loaded magazine), the single stack pistol is 5.11 oz lighter (~20% lighter).

As just mentioned when comparing weights of single stack vs double stack pistols, single stack pistols have a lower magazine capacity. This is obviously a pretty big negative. With that said, the decreased width and weight can make it far more comfortable to carry. It's better to have a comfortable firearm you'll actually carry, then one with a larger capacity that will stay at your house.

Why 9mm?

9mm is the most popular caliber for concealed carry. It's difficult to get exact figures of how popular it is, but a poll on the USA Carry forum had 40.01% of members choose 9mm as their favorite concealed weapon caliber.

USA Carry Forum Most Popular Caliber for Concealed Carry

As discussed in our comparison of pistol calibers, the FBI, U.S. Military, and the majority police forces have transitioned to 9mm from larger calibers in recent years, largely because 9mm offers similar levels of stopping power, while having less recoil. This effect is even more pronounced when talking about ultra small and lightweight subcompact pistols.

When choosing the best pistols of any category, it's important to note that there are a ton of great options available today. Modern technology, combined with a competitive market, means that there is no shortage of incredible manufacturers making excellent guns. Taking that into account, we've tried to outline the pros and cons of the different available options that we personally own or have used a great deal.

SIG Sauer P365

Okay, I lied. I'm starting the list off with a double stack pistol, the SIG Sauer P365. "Why?" you ask?

The P365 is somehow as thin as the single stack pistols on this list, while having a magazine capacity of 10 rounds (flush magazine) or 12 rounds (extended mag).

The major drawback of the P365 is its price, but if you think about what you're getting for the money, the price seems a lot more reasonable. First of all, in terms of magazine capacity and thinness, this pistol is a unicorn. Aside from that, it comes stock with tritium 3-dot night sights and an above average trigger. Additionally, it has slide serrations on both the front and rear of the slide.

This saves you from having to spend additional money on the most common upgrades of other pistols on this list.

*depending on magazine

While the P365 is one of the smallest single stack pistols on our list, it still fits comfortably in my average sized hands with the extended 12 round magazine. As is the case with all SIGs, the grip angle is fantastic.

Not everything is perfect about the P365, however. Early versions of the pistol were plagued by major issues, most notably broken firing pins. Catastrophic failures like this are not what you want out of a self-defense firearm.

SIG Sauer has fixed all of the issues over time and I'm confident enough in my newer P365 to use it for concealed carry. They went to extreme lengths to resolve the issues, including redesigning the striker and reevaluating their manufacturing supplier. P365 owners less confident that myself have chosen to upgrade to aftermarket firing pins, like this stainless steel firing pin by Lightning Strike.

For what it's worth, I've shot at least 3,000 rounds with all factory parts and had no issue.

Those of you who feel the P365 is too risky to use for concealed carry or any other serious use should keep reading because our next couple of picks are from the most trusted and reliable manufacturer.

Glock G43

Glock G43

Generally speaking, Glocks are the go to recommendation for striker fired pistols in nearly any category. The Glock 43 brings the reputation and reliability of Glock to an ultra compact package. This pistol is incredibly popular among concealed carriers.

Now I must first admit I'm not the biggest fan of Glocks generally. With that said, I really don't think there's anything too amazing about the G43. At around the same price as the SIG Sauer P365, it's somehow both wider and carries 4 less rounds in its magazine. While Glocks are known to be incredibly reliable, any of the pistols on this list are at the least very close in reliability.

If you are, however, one of the many diehard Glock fans, you may wan to check out this Glock 43 with night sights... or move on to our next Glock!

With only a 6 round stock capacity, you may want to consider getting a magazine extender, like this one from TangoDown or buying some larger Glock magazines. If you buy a Glock with factory sights that aren't night sights, you may want to check out the best Glock sights.

Glock 43X

If you want to go with Glock reliability, then the 43X is likely the best single stack pistol for you. Unlike the regularly G43, I can actually get behind the G43X.

Its slightly larger size brings with it a 10 round magazine capacity, 4 more than the original G43. This seems to be Glock's best attempt at an answer to the P365 which was eating into their market share of subcompact pistols.

You probably notice one major difference of this handgun compared to other Glocks, the silver slide. It's coated with the same compound as the G19X that underwent military trials. It also has front serrations.

If you want to be as confident as possible in your CCW, but don't want to fully sacrifice magazine capacity, go with the G43X. If you click the button to the left, you'll be taken to one with night sights, or you can click here to see one without them.

Walther PPS M2

I'm a huge fan of Walther Pistols and my thoughts on the PPS M2 are no different.

Like all Walther pistols, the PPS M2 has fantastic ergonomics and a great trigger, with short travel time and a fairly light trigger pull. Another common feature of Walther pistols, including the PPS, is relatively deep front and rear slide serrations which make it easy to rack the slide.

The PPS M2 comes with two magazines, a 6 round flush magazine and a 7 round extended magazine (pictured left). There's also an 8 round magazine available, which can be found here. Keep in mind, the extended magazines mean a taller overall pistol.

The rear of the PPS also has a red cocking indicator to help indicate whether there's a round in the chamber.

All in all, I love the PPS for a single stack pistol and feel that it shoots flat for such a small, lightweight firearm. It is, however, a bit larger than most of the pistols on this list, despite its limited capacity.

Recommended Upgrades and AccessoriesTrijicon Ngiht Sights for Walther PPS

While the PPQ (and all the other pistols on this list) are great, there's a few potential aftermarket accessories I always recommend for pistols you plan on concealed carrying. If not running a red dot sight, tritium filled night sights are a must in my opinion. They glow in the dark, making it possible to see your sights day or night. I'm also a fan of laser sights for concealed carry.

Unlike the PPQ, the PPS comes standard with metal sights, which is nice. Despite this, I prefer to have tritium night sights, for which I'd recommend this Trijicon set (see on Amazon or Brownells). I'd strongly recommend this set up instead of getting the PPS M2 LE Edition, which has phosphoric night sights. To avoid straying too far from the focus of this article, I'll just say "tritium > phosphoric acid for night sights."

Lasers are also always a great idea for help with target acquisition and you can't go wrong with Crimson Trace's laser sight for the PPS M2. I'd strongly consider opting for this bundle which includes a Blade Tech holster that is meant to fit the PPS M2 with a mounted laser.

Springfield XD-S

Springfield XDS Mod-2

The entire Springfield XD line of pistols is fantastic. I've personally found them all to feel incredibly comfortable and easy to shoot.

Like Glocks, Springfield pistols are very frequently recommended for concealed carry.

The most notable feature of the XD series is the grip safety. While not everyone is a fan, it adds an additional level of safety for those that feel the need for it. It is, however, removable if you end up not liking it.

The XD-S is one of the largest pistols on our list in terms of length and height, but also one of the thinnest. For those who are fine with concealing the size, you'll find that it's a lot more comfortable to shoot than many others on the list. It comes with both a 7 round flush magazine and a 9 round extended grip magazine.

M&P9 2.0 Shield

M&P9 Shield M2.0 W/ Night Sights

The Smith & Wesson M&P9 Sheild is another wildly popular concealed carry pistol that I'm not the biggest fan of in its stock set up. I do have friends that own them and love them, but I also know a couple people who have sold theirs and chosen to carry something else. Personally, my biggest complaint is the weird trigger, though that of course could be swapped out.

What I do love about the Shield M2.0s is their aggressive grip texture. I wish more manufactures would take note of this.

To the left, we've listed the M&P9 Shield with night sights, but you can also find them in a lot of other set ups at Brownells, including: With or w/o night sights, with or w/o thumb safeties, with or w/o lasers, etc. Along with Glocks, M&Ps have the largest variety of aftermarket parts.

Final Thoughts

If you're in the market for a single stack 9mm pocket pistol, we'd actually recommend opting for the SIG Sauer P365 double stack pistol, which is as thin as most of the single stack options and has a greater magazine capacity.

If you want to go with the most trusted brand in striker fired pistols, we like the Glock 43X best.
