Does Size Matter: Handgun Choices

Handgun Size

Schools of Thought

There are many schools of thought when it comes to which size gun, and which caliber of ammunition, is best for concealed carry purposes. 

Some say that larger calibers, such as .40 S&W or .45 ACP are best, because you can stop a potential attacker with a single shot, eliminating the threat quickly.  

Others take the opposite approach, opting for a smaller caliber like 9mm because they can carry a higher number of rounds on them, good in case you need to fend off a group attack.  

Still others subscribe to the notion that the best gun is the one you wear every day and larger, bulky guns tend to be left at home. For them, a smaller .38 Special or .380 is the most comfortable gun, and the one that gets carried everywhere.

In this article, we will examine the different sizes of concealed carry guns and ammunition, as well as different philosophies taken by gun owners.

Concealed Carry Handgun Sizes

Firearms manufacturers don’t standardize the terms they use when naming their guns.  There can be a significant size difference between “compact” handguns from one maker to the next.  In fact, even within a company, the word can seem to be applied randomly.  

Take Ruger, for example, the Ruger SR9C (C for compact) is a full size pistol with a double stacked 17+1 capacity that has had its barrel and height reduced slightly from the larger SR9.  Juxtapose that with the Ruger LCP (Light Compact Pistol), which is one of the smallest, lightest pocket pistols ever made.  Ruger seems to use the word compact liberally.

For the purposes of this article, we will classify carry guns into four size categories: Micro, Small, Medium, and Large.  Examples of each category are:

  • Micro: NAA Mini Revolver, Derringer, Phoenix Arms Raven
  • Small: Ruger LCP, S&W Bodyguard, S&W J Frame Revolver
  • Medium: S&W Shield, Sig Sauer P365, Glock 23
  • Large: 1911, Glock 17, Beretta 92F, Sig Sauer P229


The Micro category of firearms is mostly a novelty, so we won’t spend much time on them.  They consist of mostly .22LR, .25 or .32 caliber guns that fit into the palm of your hand.  

The Derringer is a two shot gun, the rounds being stored directly in the two barrels.

The North American Arms Mini Revolver is, you guessed it, a revolver.  It’s a shrunken down version of a full size revolver, with interchangeable .22LR and .22 Magnum cylinders.  It might be a neat little gun to show your friends, but that’s about all it’s good for.


Versatile, concealable, and extremely lightweight.  That describes handguns in the small category. 

They are small enough to be carried a number of different ways; waist holster, belly band, pocket or ankle holster.  Most of the guns in this category are small calibers, such as .380, .38 Special, or .357 Magnum.  

They generally have a smaller capacity because of their small size, usually around 6 to 8 rounds.  Because of the small size and small caliber, they are a favorite among new gun owners.  Smith & Wesson, in fact, caters to women shooters with its lightweight Ladysmith .38 Special revolver.  

Experienced gun enthusiasts, however, tend to stay away from this category.  There is a standard equation that most concealed carriers stick to that goes something like this:

Higher Caliber = Less Rounds

Lower Caliber = More Rounds

Explained, it simply means that shooters are willing to sacrifice capacity when they carry a larger caliber, or sacrifice large caliber when they can carry more rounds. 

This equation is mostly applied to our next category, Medium.  The reason most experienced carriers stay away from the Small category is they generally have lower calibers AND less rounds.  Most carriers are not willing to sacrifice both. (.357 Magnum is an exception. High velocity round in a small diameter.)

The area where Small really excels is concealability.  Because of their small size and light weight, these guns are easily concealed and comfortable to wear all day, every day.  

It’s often said that the best gun is the one you carry every day.  This means that all the research into calibers, capacity, holsters, etc., is for naught if you don’t actually carry the gun.  

Large, heavy guns can be hard to conceal and can be uncomfortable, especially when sitting.  That’s why large guns tend to be left at home, even by the most ardent carrier.


Medium is the group that gets the most love from concealed carry enthusiasts.  Many of the most popular carry guns fall into this category.  These guns offer a wide variety of calibers and capacities.  Many of the top selling handguns all come from this category.

The most common calibers for concealed carry are 9mm, .40 S&W, and .45 ACP.  These three, in fact, have been the subject of much debate.  With Medium carry guns, you have traditionally gotten either large caliber (9mm, .40, .45), or large capacity (12-15 rounds), but not both.

Recently, however, several new guns have been introduced that offer large capacity in large calibers.  

The P365 from Sig Sauer, for example, is a 9mm with a double stacked, 12 round magazine.  Sig has managed to design a double stack magazine while keeping the frame 1-inch thick for maximum concealability.  They did this by first designing the magazine, and then designing the gun around it.  The Glock 23 Gen 4 similarly holds 13 rounds of .40 S&W, with a thickness of just over 1-inch.


Everyone loves big guns.  Big calibers, large capacities.  However, these guns are significantly harder to conceal than their smaller brothers. 

Full size pistols give you the peace of mind of knowing that you are well armed to respond to any threat you might face.  The Glock 17, for example, offers 17+1 capacity of 9mm.  The 1911 boasts the largest caliber commonly concealed, the .45 ACP.

For die-hard carriers of large handguns, concealment is often an issue.  Many concealed carriers change their EDC (every day carry) gun as the seasons change.

In the fall and winter, when baggier clothes and jackets are common, they can carry larger guns.  In the spring and summer months, they transition to a smaller gun that conceals better in shorts and a tee shirt.

However there are some, that just love carrying the large handguns no matter the weather. If you can carry it comfortably, then why not. I always recommend the largest gun you can comfortably carry.


In the end, size DOES matter.  But that does not mean, the bigger the gun the better.  

What it does mean is you have to determine how much comfort you are willing to sacrifice to carry the the size gun you want and the amount of ammo you want.  

It is a balancing act that all concealed carriers face.  Some go the small route and are very happy, while others go the large route and are very happy.  The important thing is to choose the size that you are willing to carry every day.
