Glock 21

Glock 21 holster

If you want to buy a Glock 21 holster you need to know what how big the gun is and how you want to use it, so that you can determine what types 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.
  • Weight: 1085 g / 38.30 oz. (loaded)

It is clear that the Glock 21 can be classed as a larger sized handgun. Thus Outside the Waistband (OWB) will be more readily available for this weapon than concealed carry types. However, in our list below we do discuss one or two that are designed for concealed carry.

5 GLOCK 21 HOLSTER OPTIONS - A Detailed Look

We have taken a detailed look at 5 options that we have identified for the Glock 21. We investigate how comfortable each one is on your body, how affordable it is and how well it fits the Glock 21.

Safariland Glock 20, 21 6378 ALS Concealment Paddle  (STX Black Finish)

If you are looking for a product 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 option from Safariland will be a very good choice 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 products tend to collapse in a little bit when the gun is out, making it a more cumbersome to contain your weapon).

It 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 is also really comfortable due to the paddle and the fact that it rides really close to the body. The comfort combined with the secure ALS system makes this selection an ideal option for those folks who needs to carry their weapon in daily life for extended periods. You can also adjust the screw to ensure you get the perfect fit for your Glock 21.

Something that we really appreciate about this choice is the suede lining inside it. We hate it when your gun gets scratches from little hard pieces of metal inside. The suede lining helps keep your gun from getting those ugly scratches!

Gould & Goodrich 803-G20 Gold Line Three Slot Pancake

We really like good looking and well made leather types here at Smoking Barrel, and this holster from Gould & Goodrich certainly is like that! It is made from thick genuine leather with double stitching, which means if you look after this 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 types, you will need to break it in before it will fit your Glock 21 smoothly.

This 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 product that will last you a long time if you look after it. It also provides decent concealability if you want to carry concealed.

BlackHawk Serpa Sporster Belt Holster

If you are looking for a really safe option, this one from BlackHawk is a good choice. 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 contain 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. It 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 for a forward, vertical or rearward draw angle depending on your preference.

Like you would expect from high-density plastic type, this product is molded to fit the Glock 21. It also has a retention screw so that you can adjust the fit to your G21.

This option is available in both left and right hand versions.

Galco KT228B Kingtuk Inside the Waistband Gun

If you are in the market for a Inside Waistband (IWB) type, then this choice from Galco will be a contender. The backing plat, which is made from leather, helps to make this a really comfortable selection that can be worn for extended periods. The product itself is made from rigid Kydex, which ensures quick and easy draws. The fact that it is a rigid product also makes it much easier to contain your weapon as it is less likely to collapse in.

Adjusting the way you want to carry it 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 option that you can wear for extended periods of time, you should look close at this Glock 21 holster option.

Fobus Tactical Speed Paddle

If you have tactical carry requirements, then this option 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. It 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 feels unnatural and even a little difficult.

Another downside though, is that it is only available in right hand version. So if you are a lefty, this 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 it. You can of course remedy this yourself if you wanted...but really we want an option that has that sorted out already.

Picking The Right GLOCK 21 HOLSTER

Let's do a quick recap of each one product to see how well they compare to each other, and which one might be the ultimate choice for your Glock 21!

The Safariland product 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. It is made from injected molded high-density plastics and has a retention screw that you can adjust, which makes for a carry option that fits the Glock 21 like a glove. It is not the cheapest one, but definitely not the most expensive option either.

The Gould & Goodrich is a top quality leather product 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 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 selection, but you get what you pay for.

The BlackHawk allows for a tight carry close to the body while also allowing for adjustment to how you want your product to cant. The SERPA Auto Lock system keeps your weapon securely in place and makes a clear click sound when you case your weapon so that you know it is securely locked in. At the current retail price, this is a bargain option to buy!

If you want to carry concealed for extended periods, the Galco KingTuk IWB is quite possibly the best Glock 21 holster option for you. The leather back plate ensures comfort, while the Kydex ensures quick and smooth holstering of your weapon. It is one of the more expensive selections on our list of Glock 21 holster options though, so probably not a good choice if you just want something for occasional carry.

The Fobus paddle is a good choice if your are specifically looking for a product that can take a tactical flashlight or laser mounted to your weapon. However its draw is not great and due to metal buttons 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 one product that can take a mounted light or laser.

Which Glock 21 holster would we choose?

The selections discussed above are excellent Glock 21 holster options, and ultimately your own requirements will determine which one is the best Glock 21 holster option for you. For us, if we had to buy Glock 21 holster right now, we would choose the Glaco KingTuk IWB holster. The fact that it is super comfortable and you can carry for extended periods of time is what tipped the scales for us.
