When you search for a Glock on the internet, the first question that will arise in your mind is how many bullets does a Glock hold? And why is Glock so popular? Is it just a plastic weapon that feels like a toy or is it an actual worth-it weapon?

Well the questions are many, where are the answers you ask? Here they are. Just stick around and you will find all the needed answers about Glock in no time. Without further ado, let’s start.

How Many Bullets Does A Glock Hold?

Well, when we speak of Glock, we define models of the gun as well. As there are several different kinds of Glock on the market that house different calibers, the total number may vary as well.

Some of them can hold around 15, some 17 and with extended clips, some can hold even 30, 33, and 50 bullets.

Why Does Capacity Matter?

As Glock extended magazines are readily available for all Glock models, no one really thinks about the capacity much. Before you begin to question why capacity matters, you will need to question what is the purpose of your Glock.

Most people purchase Glock for recreational shooting, self-defense, and concealed/open carry. Some even carry glocks as a secondary weapon in hunting. As the gun is capable of doing some close range shooting, it can come in handy when you are in a pinch and can’t bring out the big guns.

If you are using a Glock for recreational shooting, the larger the merrier. If you have more than 30 bullets in your mag, you can shoot for a while without worrying about anything at all. And as for self-defense, 17 rounds are perfectly fine but it doesn’t hurt to have room for more.

Glock Magazine Capacities

Semi-automatic pistols are usually fed from a removable magazine. Thus making the reload time simpler and easier. The difference between a magazine and a clip is distinct. A magazine typically holds cartridges in one or two different layouts.

Single Stack

Single-stack magazines are the most common among pistols. As the name suggests, the magazine stacks one bullet on top of another in a stack. When the pistol chambers a bullet from the stack, the magazine has a mechanism that pushes the bottom bullet upwards and makes the top bullet ready to be chambered next.

Double Stack

Double stack magazines have cartridges in a stack or dual feeding column. They lower the reload time and increase the total capacity of the magazine at the same time as well.

While you can debate for years about the number of bullets a pistol caliber should hold, it’s not always necessary for everyone to have the same opinion on one thing. The standard Glock holds 17 rounds of 9mm bullets.

Should I Buy Glock Magazine Extensions?

If your state allows you to use more ammo with your Glock, then I don’t see why you shouldn’t extend your magazines. In fact, if your state has no bans on drum magazines, I urge you to try out drum magazines for Glock at least once. Trust me, your experience will be elevated to the next level.

How Many Rounds Do You Need?

Well, it’s impossible for me to say how many rounds you should carry with you. Realistically, you can carry a crate along with you in your backpack. But it’s not something you should do tho. You should carry the amount that you can predict that you need and one or two extra mag worth as a safety measure.


As you can see, the capacity varies from model to model and it varies even more when it comes to magazine extension kits. Depending on the state you are living in and the legal rules you will need to follow, magazine extension kits will vary as well.
