Why Are Glocks Popular in the Market?

Glock 9mm models have almost a 65% market share in the US, making the model a celebrity in the gun world. It is the preferred pistol for civilians and law enforcement, and the Glock is known for spending effort and time to work on how printable the pistol will be.

Pointability is the pistol's natural ability to be like an extension of the shooter's hand and eye coordination. Therefore, the user-friendliness, high pointability, and high accuracy in shooting the Glock have made the pistol much easier to aim than competitors.

In addition, Glock has been reinforced in public through the popular culture from the 1990s in movies and TV shows. For instance, in Die Hard 2, the actor Bruce Willis gives a long speech on the many Glock advantages and also the Glocks also feature in popular hip-hop music.

What to Consider Before Choosing a 9mm Glock Model

1. Concealed Carry vs. Open Carry

When choosing the best 9mm Glock models, one of the most important factors is whether you want to conceal or open carry your pistol. This decision on the best way to carry will be heavily influenced by why and how you will be using your firearm.

a). Open Carry

One of the major benefits of open carry is how easy it will be to access your firearm in an emergency. If you decide to use concealed carry, there are techniques you can practice to quicken your drawing time. However, an open carry holster will be generally faster to draw.

b). Concealed Carry

Most holsters for concealed carry place the gun directly against your skin which can get uncomfortable. Open carry will give a user a more comfortable fit as it moves the gun away from your body. The size and designs of some 9mm Glock models make them ideal for concealed carry, including:

  • Search for the slimmest, compact and lightweight models for concealed carry
  • If you want to carry a Glock openly, opt for a larger pistol with a large magazine capacity meaning it will new fewer reloads
  • The best-concealed carry models designed for this specific purpose are Glock 19, 26, 43, and 48.

Before deciding, check the legal restrictions in your state since some states have a constitutional carry, meaning you can legally carry a handgun with no permit or license. However, some states require restrictions or permits on who can carry a firearm and how it should be carried.

2. Calibers and Sizes

Glocks come in various calibers and sizes. To better make a choice, you will need to understand the different caliber options available to gun owners looking to buy a Glock

a). 22 LR – G44- The Glock 44 is a super-compact pistol option, and it's the first Glock to chamber a .22 caliber round, making it suitable for learning and training.

b). 9×19- This is the classic golden caliber where it features the Glock 17, 19, 26, 34, 43, 45, and 48. In addition, all the following variations and generations will also fall under this caliber.

c). .380 Auto – G42- This subcompact pistol is perfect for shooters looking for a small 6-round pistol.

d). .357- It includes the models 31, 32, and 33 and their subsequent generations and variations where the Glock 32 is compact and the Glock 33 is a subcompact.

e). .40- This caliber has models such as 22, 23, 24, 27, and 35 but also their subsequent generations and variations.

f). .45 Auto- This caliber has 21, 30, 36, and 41 models and subsequent generations.

g). .45 G.A.P.- This caliber includes the models 37, 38, and 39.

h). 10mm Auto- This caliber has 20, 29 and 40 models.

3. Action Type

All Glock 9mm pistols are either single or double-action, which means the number of actions a single trigger pull can perform.

Single action pistols only fire when you pull the trigger, and when the hammer is released, it starts a chain reaction causing the bullet to leave the barrel. These are the landscapes of striker-fired pistols, with lighter trigger pulls, meaning less weight on the trigger to squeeze a shot. Also, you will have to pull the hammer back manually between every bullet.

On the other hand, double-action pistols perform two actions where they pull the hammer back and release it to fire a bullet. They need more finger pull, but they may allow you to release rapid-fire since you don't have to pull the hammer back yourself each time. These Glock pistols are suitable for home defense or concealed carry.

4. Grip Quality

Many Glock 9mm models come with excellent grips, ergonomic shapes, or textured surfaces. The textured surfaces are beneficial because they make holding the pistol easier even with a sweaty palm.

Also, ergonomic shapes are more comfortable, preventing your hand from cramping. This is especially useful if you have to hold your 9mm Glock for long sessions at a gun range.

Lastly, some models have removable, replaceable grips to achieve a customizable shooting experience, and they can improve the hand control, feel and comfort.

5. Optics Support

Check if your Glock pistol has any iron sights straight from the box because sights allow you to hit your target better even at a distance. Also, check if the front and rear sights are adjustable, which will allow you to compensate for different variables. Finally, the fixed day and night sights help increase lighting situations where your pistol sights remain useful.

6. Rail Space

Check whether you need a 9mm pistol with a mounting rail where some pistols allow you to have new attachments such as red dot sights and other optics beneath the barrel or on top of the pistol. However, other Glock models lack this functionality but have affordability.


Glocks are well-known for their durability, dependability, accuracy and consistency, so it's no surprise that 9mms are popular in gun stores. However, with so many Glock 9mm models, there is something for every purpose and need for users looking for a quality new gun that will last a lifetime. Whatever the reason you are shopping for a Glock model, this article will help you narrow down your prospective choices.
