When choosing what gun to carry on a daily basis, one of the attributes that divides opinion is whether to carry a double stack or single stack pistol. It is worth thinking about, as that directly impacts the number of rounds that you have in your carry gun.
After all, you want to pick the right tools for everyday carry including the right gun, belt and .
Double Stack Offers More Capacity...But Do You Need It?
The reason why the double stack magazine was invented in the first place is fairly obvious: carrying capacity. In point of fact, the double stack magazine was invented by one Dieudonne Saive, a Belgian in the employ of Fabrique Nationale, now FNH. Saive was working on a new gun for the French, and they specified 10 or more rounds in capacity.
The guy who designed much of the rest of the gun was one John Moses Browning, and the pistol in question was the Browning Hi Power. Browning passed away before it was completed, and Saive finished the work. Plenty of people have carried one for service or protection purposes in a ever since, as it is an enduring pistol design.
Since the double-stack magazine staggers more rounds, it naturally offers more firepower to the person carrying it. But do you actually need it?
This is the sticky wicket. The average defensive shooting takes place at very close range, with very few shots fired into a single assailant and is over very quickly. You don't need 13 to 15 rounds for that; 5 or 6 is likely twice the number of rounds you need.
Unless you need more than that. There are accounts of people emptying an entire revolver into intruders/bad guys at near point blank range and barely slowing them down. Police officers have put entire magazines into suspects with almost no discernible effect.
How do you know what's going to happen if you get into a self-defense scenario? You don't. You can't. So it is literally the case that if you ever have to use your gun, chances are you won't have to fire more than a few shots...but you may have to fire a lot of them.
Single Stack Is Very Popular For Concealment
The single-stack subcompact auto is, without question, the concealed carry pistol of the modern era. The snubbie has given way to the plastic striker pistol (which some believe is a crying shame) with a 6- to 8-shot capacity.
Granted, there was the Commander and Officer frame before the first Baby Glock hit the scene as well as the Walther PPK and others, but one digresses.
Why are small single-stack guns so popular? Easy concealing. It's not that a double-stack pistol can't be concealed; they can. It's just that a single-stack gun, many of which come in at 1 inch or less in width, hug to the body closer than a gun that's 1.2 inches or wider does.
Granted, a person's body type comes into play. A person with a larger frame and broad shoulders and perhaps a few extra pounds will be able to conceal a double-stack compact with few issues. A person closer to average (the typical American male is around 5'9" and isn't too beefy) is going to have so much printing with a double-stack gun that he has to change his name to Gutenberg.
Weight is another factor; a few extra ounces doesn't seem like much but when you're carrying the gun around all day...it makes a difference.
Should I Get A Single-Stack or Double-Stack Magazine Pistol For CCW?
The truth is that there's no perfect CCW pistol, whether it uses a single-stack or double-stack magazine. There is however, a really good CCW gun for YOU out there.
It's up to you to decide for yourself what kind of gun you want to carry. Do you prefer a striker gun? Or would you rather have a DA/SA pistol? Do you want a dozen or more rounds of 9x19 Para or are you comfortable with 6 rounds of .45 ACP? Or, for that matter, 6 rounds of 9mm? Or are you good with 5 or 6 of .38 Special +P?
Also, consider...well, you, and how you want to carry. Are you short and stocky? Short and skinny? Tall and lanky? Tall and carrying a few extra pounds? Or are you so swole that you have to buy 4X T-shirts to fit your barrel chest, bowling ball delts and 24-inch pythons?
Point being that body shape is going to impact how easy some guns conceal. If you're a bit on the small side, a slimmer, shorter pistol (which would naturally be a single stack) will be a bit easier to conceal.
How you carry also comes into play. A big, bulky double-stack (Sig, we're looking at you!) is not the easiest to conceal inside the waistband, unless you're the size of an NFL offensive lineman. However, outside the waistband in a high-ride OWB under a jacket...a bit easier. A compact single-stack is easy and rather comfortable to carry in an IWB holster. Granted, plenty of compact double-stacks do as well.
So, which is better for concealed carry? They're both great, depending on what you need or want from a pistol and what sort of gun you are going to be able to conceal well, carry comfortably but also - and this is important - shoot well.
All of this doesn't matter if you can't hit the broadside of a barn with your gun. If you're trying to nail down a carry gun, get out there and shoot some. Find a concealable pistol you can shoot decently, and then worry about the rest. If it happens to be a small single-stack, awesome. If it's a compact double-stack, that's great too. If it's a 1911, even better that's good too.
FAQs
What is the difference between single-stack and double-stack magazines?
A single-stack magazine holds cartridges in one straight column, resulting in a slimmer grip and lower capacity; a double-stack staggers rounds in two columns for higher capacity with a wider grip profile. This affects concealability, shootability, and reload frequency for everyday carry.
Which is better for concealed carry: single stack or double stack?
Single stack prioritizes concealment with a thinner, lighter profile that reduces printing under fitted clothing, while double stack prioritizes capacity and often improved shootability due to fuller grips and weight. The best choice depends on body type, wardrobe, carry position, and tolerance for capacity vs concealment trade-offs.
How does grip width impact concealment and control?
Slim single-stack grips reduce printing and can fit smaller hands better, improving reach to the trigger and controls. Wider double-stack grips fill the hand, often improving recoil control and shot-to-shot speed, but can print more under light garments.
What capacity differences matter for EDC?
Single-stack 9mm micro-compacts commonly hold 6–8 rounds (flush), while double-stack compacts often hold 12–15 rounds with comparable barrel lengths. Higher on-board capacity reduces reloads in defensive incidents but increases grip circumference and weight.
Do modern “micro double-stacks” change the trade-off?
Modern designs (often called double-stack micros) bridge the gap by offering near double-stack capacity in a slim footprint comparable to legacy single-stacks. These designs can maintain concealment while meaningfully increasing capacity, reshaping EDC choices for many carriers.
How does printing differ between single and double stack setups?
Single-stack pistols reduce side-to-side bulk, lowering the chance of the grip outline showing through clothes. Double-stack frames increase grip width and heel bulk, making holster selection, belt stiffness, and wedge/claw tuning more critical to minimize printing.
Which is easier to shoot well under stress?
Double-stacks often feel more controllable due to fuller grips and added mass that soaks recoil, aiding rapid, accurate follow-up shots. Single-stacks can be snappier and require stronger fundamentals on grip and recoil management to match performance.
What about reload speed and spare magazines?
Lower-capacity single-stacks often drive carriers to stage spare magazines and train emergency/tactical reloads. Double-stacks may reduce reload frequency, but carriers should still stage spares for malfunctions and contingencies.
How do clothing and carry position influence the choice?
If you wear fitted shirts or minimal cover garments, a single-stack (or micro double-stack) at appendix IWB often conceals better. If jackets or looser garments are common, a compact double-stack at strong-side IWB or OWB with concealment aids can disappear effectively.
What holster features help mitigate double-stack bulk?
Use a rigid IWB holster with a concealment claw, foam wedge, and proper belt line height to tuck the grip in. A quality gun belt stabilizes the load, while adjustable ride height and cant tailor concealment and draw stroke for wider frames.
Are single-stack pistols more reliable than double-stack?
Both can be highly reliable; quality and maintenance matter more than column count. Single-stacks may avoid rare stagger-feed binding, while double-stacks from reputable makers are proven when magazines are maintained and springs replaced on schedule.
How does hand size affect the decision?
Smaller hands often benefit from the reduced circumference of single-stacks for consistent trigger press and control. Larger hands usually gain leverage and comfort from double-stacks, improving recoil control and speed.
What training considerations differ between formats?
Single-stacks demand dedicated recoil management and reload practice to offset capacity limits. Double-stacks benefit from drill volume on concealment mechanics to control printing and from strong-hand grip work to exploit the fuller frame.
Does weight meaningfully change carry comfort?
Single-stacks reduce loaded weight, improving comfort during long wear and active movement. Double-stacks add ounces that can aid recoil control but require better belt/holster support to maintain comfort and concealment.
Which has better aftermarket and support?
Double-stack formats (especially popular models) typically enjoy broader magazine, holster, and accessory ecosystems. Many legacy single-stacks still have excellent support; verify availability of holsters, spare mags, and night sights before deciding.
What are good use cases for each format?
Choose single-stack when maximum discretion, light dress, or minimal bulk is paramount. Choose double-stack when higher capacity, faster follow-up control, and glove-friendly handling are priorities and concealment conditions allow a wider grip.
