If you want to buy a holster for your Glock 21 you need to know what how big the gun is and how you want to use it, so that you can determine what types of holster might be appropriate.
Weapon Size and Weight:
The Glock 21 Gen4 has the following measurements:
Length: 204 mm / 8.03 in.
Barrel Length: 32 mm / 1.26 in.
Width: 32.50 mm / 1.27 in
Height: 139 mm / 5.47 in.

It is clear that the Glock 21 can be classed as a larger sized handgun. Thus Outside the Waistband (OWB) holster will be more readily available for this weapon than concealed carry types of holsters. However, in our list below we do discuss one or two holster that are designed for concealed carry.
5 GLOCK 21 HOLSTER OPTIONS – A Detailed Look
We have taken a detailed look at 5 of the holsters that we have identified for the Glock 21. We investigate how comfortable each holster is on your body, how affordable it is and how well it fits the Glock 21.
Safariland Glock 20, 21 6378 ALS Concealment Paddle Holster (STX Black Finish)
If you are looking for a holster that is specifically designed to fit your Glock 21 and that also has a retention system to keep your weapon securely in place, then this holster from Safariland will be a very good Glock 21 holster option for you to consider. The fact that it is made from sturdy molded high-density plastics ensures that it is smooth and easy to holster your weapon again once you have drawn it (sometimes softer holsters tend to collapse in a little bit when the gun is out, making it a more cumbersome to holster your weapon).
The holster uses the Safariland ALS (Automatic Locking System) to lock the weapon in place while holstered. Once you deactivate the ALS, it is a straight draw. The ALS system allows you to move around with your weapon a lot more without having to worry about your gun popping out. The carry for this holster is also really comfortable due to the paddle and the fact that the holster rides really close to the body. The comfort of the holster combined with the secure ALS system makes this holster an ideal option for those folks who needs to carry their weapon in daily life for extended periods. You can also adjust the screw of the holster to ensure you get the perfect fit for your Glock 21.
Something that we really appreciate about this holster is the suede lining inside the holster. We hate it when your gun gets scratches from little hard pieces of metal inside the holster. The suede lining helps keep your gun from getting those ugly scratches!
Gould & Goodrich 803-G20 Gold Line Three Slot Pancake Holster
We really like good looking and well made leather holsters here at Smoking Barrel, and this holster from Gould & Goodrich certainly is a holster like that! The holster is made from thick genuine leather with double stitching, which means if you look after this holster it can last you for years. Over time the leather will also mold to your body, making it a very comfortable carry. Of course you can also decide on the cant you want thanks to the belt loop options that provide for a straight carry option or a slight forward cant carry option.
As with all leather holster, you will need to break the holster in before it will fit your Glock 21 smoothly.
This holster is a little more expensive than some of the other Glock 21 holster options we have on here, but for the money you pay you get a quality holster that will last you a long time if you look after it. The holster also provides decent concealability if you want to carry concealed.
BlackHawk Serpa SpoRusseter Belt Holster
If you are looking for a really safe holster, this holster from BlackHawk is a good option. It has the SERPA Auto Lock system which locks your weapon securely into place. What is nice about this system is that it makes a clear click sound when you holster your weapon so that you know it is locked and secure.
Drawing your weapon is also pretty straight-forward due to the quick release tab that makes sure you can get your G21 out nice and smoothly. The holster also makes for a close carry to your body, so your weapon does not flop around if you are moving around/runnning. Not only that, but you can also adjust the cant of the holster for a forward, vertical or rearward draw angle depending on your preference.
Like you would expect from high-density plastic holster, this holster is molded to fit the Glock 21. It also has a retention screw so that you can adjust the fit of the holster to your G21.
This holster is available in both left and right hand versions.
Galco KT228B Kingtuk Inside the Waistband Gun Holster
If you are in the market for a Inside Waistband (IWB) holster, than this holster from Galco will be a contender. The backing plat, which is made from leather, helps to make this a really comfortable holster that can be worn for extended periods. The holster itself is made from rigid Kydex, which ensures quick and easy draws. The fact that it is a rigid holster also makes it much easier to holster your weapon as the holster is less likely to collapse in.
Adjusting the way you want to carry the holster is pretty easy thanks to the removable belt metal clips that can be moved up or down in the corresponding holes in the leather, enabling the user to set the carry height and angle.
If you want a concealed carry holster that you can wear for extended periods of time, you should look close at this Glock 21 holster option.
Fobus Tactical Speed Holster Paddle
If you have tactical carry requirements, then this holster from Fobus will be a solid option for you to consider. It is designed to allow for additional tactical features such as lasers and lights mounted to your weapon. Besides that, it also comes with a lifetime warranty!
It does not have the fancy locking systems like the Safariland or the BlackHawk options, but it does have a muzzle stud and thumb break to keep the weapon secured in place. The holster was designed with the thumb break strap over the trigger guard in such a way as to present a straight and quick draw when needed. However a number of users complained that the draw of this holster feels unnatural and even a little difficult.
Another downside for this holster though, is that it is only available in right hand version. So if you are a lefty, this holster is not the Glock 21 holster for you. What we also do not like is that a lot of users mentioned their weapons getting marks on it due to metal buttons used in the holster. You can of course remedy this yourself if you wanted…but really we want a holster that has that sorted out already.
Picking The Right GLOCK 21 HOLSTER
Let’s do a quick recap of each holster to see how well they compare to each other, and which holster might be the ultimate choice for your Glock 21!
The Safariland holster is a solid option for folks that have to carry their weapon on a daily basis and want to be sure that the weapon will be securely kept in place. The holster is made from injected molded high-density plastics and has a retention screw that you can adjust, which makes for a holster that fits the Glock 21 like a glove. It is not the cheapest holster, but definitely not the most expensive holster either.
The Gould & Goodrich holster is a top quality leather holster that is a good option for folks that might want to carry their G21 concealed. Made from thick leather with double stitching, it will last you for years to come if looked after. Comfort for this holster is really good due to the canting options and the fact that the leather will mold to your body shape over time. Not a cheap holster, but you get what you pay for.
The BlackHawk holster allows for a tight carry close to the body while also allowing for adjustment to how you want your holster to cant. The SERPA Auto Lock system keeps your weapon securely in place and makes a clear click sound when you holster your weapon so that you know it is securely locked in. At the current retail price, this is a bargain holster to buy!
If you want to carry concealed for extended periods, the Galco KingTuk IWB holster is quite possibly the best Glock 21 holster option for you. The leather back plate ensures comfort, while the Kydex holster ensures quick and smooth holstering of your weapon. It is one of the more expensive holsters on our list of Glock 21 holster options though, so probably not a good choice if you just want a holster for occasional carry.
The Fobus paddle holster is a good choice if your are specifically looking for a holster that can take a tactical flashlight or laser mounted to your weapon. However the draw of this holster is not great and due to metal buttons in the holster it leaves marks on the slide. For that reason we would rather consider some of the other Glock 21 holster options if we do not have to get a holster that can take a mounted light or laser.
So which Glock 21 holster would we choose?
The holsters discussed above are excellent Glock 21 holster options, and ultimately your own requirements will determine which holster is the best Glock 21 holster option for you. For us, if we had to buy a holster for the Glock 21 right now, we would choose the Glaco KingTuk IWB holster. The fact that it is a super comfortable holster that you can carry for extended periods of time is what tipped the scales for us.
