Here’s What Every Glock Owner Needs to Know Before Buying

As many shooters know, Glocks tend to have a cult-like following. For instance, they have diehard followers that love the brand, and swear by it. They won’t recommend anything else – especially to a new shooter.

However, there are others that say the best advice to a new Glock buyer is to not buy the Glock at all. This group believes that there are many alternatives available. And that you should seek out all of them instead of settling for the Glock.

Well, no matter which side of the fence you fall on, one thing is clear. The brand has built up a reputation for itself for accuracy, durability, reliability, and simplicity. And they can do it all while maintaining some incredible value.

Now, to be fair, if a shooter is wanting a new handgun, they might head over to the Glock. After all, this popular brand has notoriety for being easy to use. However, it’s smart for them to prepare in advance so they can know what they’re getting into.

If a new handgun buyer is looking at Glocks, there’s some things they’re going to need to know before taking one of these home. After all, they’ll need to get the best bang for their buck across the board. And they deserve the chance to figure out what’s right for them.

To help educate new handgun shooters, The Truth About Guns has written a list of things to consider before buying a Glock. These include:

1. Choose a size

All GLOCKs look and function the same, but they come in various sizes and calibers. To determine which model — or models — is best for you, first decide how you want to use it.

Home defense – It’s easier to shoot a handgun with a longer slide accurately than a shorter gun; the longer distance between the front and rear sight helps you aim. It’s easier to shoot a larger gun generally; it’s more secure in your hand.

GLOCKs on parade

If you’re not going to rock your GLOCK outside the home, buy a full-size gun: either a longslide (G17L, G24, G40 MOS) or “standard” GLOCK (G17, G22, G20, G21, G37, G31).

Carry – Unless you’re open carrying, you’ll want a GLOCK you can hide on your person. Restrict your GLOCK selection to a compact (G19, G23, G38, G32) or subcompact (G30, G33, G36, G42, G43).

Home defense and carry – Compact GLOCKs are the way to go for a dual purpose pistol. Choose from the G19, G23, G38 and G32. That said, “crossover” GLOCKs (G19x) with their full-sized frames (for a secure grip) and shorter slides are also a good choice — provided you can hide that big honking handle.

Fun! – Longslide or “standard” GLOCKs (G17L, G24, G40 MOS, G17, G22, G20, G21, G37, G31) are the most fun to shoot — because they’re the easiest to shoot.

NOTE: Some, maybe even most GLOCKs are too big for small-handed shooters. Try before you buy! While holding a GLOCK properly, make sure your entire first finger pad can rest on the trigger without the rest of the finger touching the gun.

2. Choose a caliber

All GLOCK variations within a given size range represent variations in caliber: the size of the cartridge (which includes the bullet) that the GLOCK stores, chambers and fires.

GLOCK sells big guns that fire small bullets (G17), small guns that fire big bullets (G36), big guns that fire big bullets (G20) and small guns that fire small bullets (G42).

The key to choosing a caliber: your ability to control the gun during and immediately after recoil (the “kick” as the gun fires).

There’s one general rule that’ll help you narrow down your selection: larger calibers (e.g., .40, .45, 10mm) are easiest to control in larger guns. The big guns’ extra mass and greater grip surface area help you “soak up” and control recoil.

Smaller rounds (eg., 9mm, .380) are easiest to control period, making them particularly suitable for carry guns.


NOTE: Larger caliber rounds (.40, .45, 10mm) are more destructive than smaller rounds (9mm, .380.) BUT shot placement is more important for self-defense than bullet size (big bullets that miss the target are worthless). Unless you’re willing to take the time and money to master a larger caliber GLOCK’s more powerful recoil, stick with smaller calibers (9mm, .380).

3. New or used?

A GLOCK is built like brick sh!t house. So you can save yourself a hundred dollars or more by buying a pre-owned GLOCK, without worrying overmuch about its performance or ongoing longevity.

Yes, there’s a chance any given GLOCK was abused to the point where it could malfunction, requiring replacement parts and/or repair. There are two ways to avoid those issues:

Buy from a reputable gun dealer – It’ll cost you more than a private sale but you’ll be buying from someone who knows the difference between a well-loved, rarely-fired GLOCK and one that’s been neglected or abused. And it’s good to buy from someone who stands behind the sale.

Inspect the gun yourself – Watch this video . . .

[NOTE: ALWAYS SAFETY CHECK A FIREARM BEFORE HANDLING. If you don’t know how to make sure a GLOCK is unloaded, learn that skill before you start the buying process. And don’t be afraid to ask someone to help you take it apart and put it back together.]

GLOCK is America’s favorite handgun. While other brands offer guns that are superior in some or many ways to a GLOCK, buying a GLOCK is a safe choice. Just make sure you buy the right size GLOCK in the right caliber for the right job — at the right price. Have fun and shoot safely!
