The Top Glock 21 Holsters

glock21sfmWhen you think of a .45 caliber handgun for personal defense, you’re probably going to think of a 1911-style model. It’s iconic, it’s a solid platform, and it’s only gotten better with time. It isn’t however, without its shortcomings; while it has been a dominant handgun for nearly a century, it’s slowly been losing ground to lighter 9 millimeter platforms.

Naturally, this has created serious debate in the concealed carry community; is it better to have an all-metal handgun with fewer rounds, or a polymer handgun with nearly double the magazine capacity?

Fortunately, there’s a compromise, and its name is the Glock 21. A polymer .45 caliber handgun with a double-stack 13 round capacity, this handgun gives you the best of both worlds; you get the polymer body and high round capability of a 9 millimeter, but you also get the stopping power of a .45 round. Whether you choose to carry it open or concealed, professionally or for personal protection, this powerful, robust handgun from Glock just proves that you don’t always have to have only one or the other.

*** For other Glock holster options (besides just the 21), here are some good choices for all Glock models

Choosing a Holster for Glock 21

Of course, like any good handgun, you’re going to need a good holster. Below, we’ve got some great examples to help you find the best Glock 21 holster for you.

BlackHawk Serpa SpoRusseter Belt Holster

With the BlackHawk! Serpa SpoRusseter Belt Holster, the word of the day is “adaptable”. Just starting with the basics, you’ve got an injection-molded polymer body designed to take abuse and, unlike leather holsters, to be impervious to moisture. Thanks to an adjustable passive retention screw and an active locking mechanism on holster body, not only will your handgun stay in the same place on your body, but your handgun will also stay in the same place in your holster.

Yet even with both locking mechanisms in place, drawing is still quick and natural; just reach down to your belt like a normal draw, but extend your index finger and press the release button. You can probably even make your draw quicker than normal by taking advantage of the speed-cut design; because the front of the SpoRusster is cut so low, you can already be placing your handgun on target even before your barrel is completely clear. With this holster for your Glock 21, your handgun stays secure and in place when it’s holstered, but the SpoRusseter releases it almost immediately when you need to draw.

But one of the best parts about the SpoRusseter is the fact that it’s on BlackHawk!’s Serpa system. Not only does this mean you can adjust the cant of your Glock 21 holster via the three screw system, but you can easily detach it from the included paddle platform and put it on a drop-leg setup, a shoulder harness, or even a MOLLE vest. For the Glock 21, which is robust enough to act as open carry or concealed carry, having the SpoRusseter holster means that you can really carry your handgun any way you see fit.

Safariland 6378 ALS Concealment Paddle Holster

Whether you’re a competitive IDPA shooter, a law enforcement professional, or someone who just likes to be active with a Glock 21 concealment holster, you’ve probably noticed that you need a lot more weapon retention capability in your holsters. Not only does this keep your handgun from simply falling out of your holster, but, especially in the case of law enforcement, a good retention holster makes it incredibly difficult for anyone to take your handgun from you.

To that end, you want to check out the Safariland 6378 Paddle Holster for your Glock 21. Like the SpoRusseter, this holster is made with solid, maintenance free injection-molded polymer to keep everything in place.

The Safariland 6378, however, is locked with a vertical button on the inside of your holster, rather than the Serpa’s horizontal button on the outside. Rather than your index finger, your thumb presses down to disengage the lock. While the two holsters are functionally similar Level II polymer holsters, the choice of draw really comes down to personal preference and which style of draw you prefer. Here are other Safariland holsters we like, including more information about the 6378 version.

Blackhawk! SERPA Concealment Holster

For shooters who like the Serpa system but are looking to upgrade the platform in a few ways, the Serpa CQC Concealment Holster absolutely has you covered. At first glance, it’s functionally identical to the SpoRusseter; same lock, same adjustability, same ability to cross platforms. However, like most things, the real devil is in the details. On the CQC, you’re going to be trading up your usual injection-molded polymer body for one that’s reinforced with carbon fiber, giving you a lot more strength and protecting your handgun from a bit more abuse.

On top of that, you’re getting a belt holster and a paddle holster attachment with the CQC, instead of just the paddle attachment you would get on the SpoRusseter.

If you feel like you want to get a little more durability out of your holster, either because you’ve been burned by cheap holsters before or you really just want to get the most out of the Serpa platform, it might be worth the extra money for the peace of mind.

Glock 21 IWB Holsters

Waistband holsters are a popular choice amongst carriers who are worried about printing, and IWB holsters are much easier to conceal than a paddle holster or belt holster. Let’s take a look at our favorite choice for the best Glock 21 IWB Holster.

Galco KT228B Kingtuk Inside the Waistband Gun Holster

Unlike the previous entries on this list, the model KT228 from Galco Gunleather is an inside-the-waistband (IWB) holster; rather than hanging outside your waistband like a traditional holster, this Glock 21 IWB holster is designed to press right up against your skin, giving you a lot more concealability. Naturally, comfort is going to be a much bigger concern, which is why Galco’s Napa leather front is a great option, much more comfortable than nylon or a rigid material.

Of course, the holster is made of a Kydex polymer and secured with either adjustable metal or nylon hooks, so not only do you have a secure fit, but you have a comfortable fit as well.

The Glock 21 actually works fairly well with the Kingtuk and other IWB holsters for concealed carry, due in most part to the size. While a larger shooter would have no problem wearing large clothes to conceal a traditional holster, smaller concealed carriers would be forced to either change their wardrobe and dress for their handgun (sticking out in public either way), or have to forgo the Glock 21 altogether in favor of a .380 or a single-stack 9 millimeter.

IWB holsters like the Kingtuk allow you to tuck your shirt in over your Glock 21 leather holster, giving you a way to naturally conceal without drawing attention. In addition, for the businessman, an IWB holster will look infinitely less suspicious; while tucking in a dress shirt would expose a traditional holster, an IWB holster is right at home, making you look professional and feel safe without sacrificing either.

Glock 21 Accessories

While they’re not necessary for using your Glock 21, we find that these accessories can make drawing, shooting, and maintaining your handgun much easier.

TALON Grips for Glock 20/21

Whatever holster you choose, it helps any draw to have a solid grip on your Glock 21. Fortunately, you don’t have to buy a custom set of handgun grips to get a better hold on your handgun; instead, you can use TALON Grips. They’re simply super-thin textured pieces of rubber that attach right to the grip of your Glock 21, and make handling, drawing, and firing infinitely easier.

If you shoot with sweaty palms, or you simply just don’t like the feel of your Glock 21 in your hands, stick on a set of TALON Grips and see if it makes handling this impressive handgun more to your liking.

Glock GT03374 Disassembly Takedown Tool Punch
