Buying Guide of The Best Glock 21 Holster 

How to choose a Glock 21 holster? 

When choosing a holster, you need to consider a few questions: Can the holster keep the gun in place? Can you quickly draw the weapon from the holster? Does the holster make the angle of the weapon uncomfortable?

Retention

A holster is useless if it can't hold the gun properly. If you can turn the holster upside down and shake the gun without stopping, this is the holster you're looking for. But instead of endlessly shaking every holster you can find, you can prioritize choosing a holster that uses the Safariland ALS - an efficient locking system. However, you should note, a holster that uses a locking system will be easier to reveal than a regular holster.

Positive Grip

In emergencies, a one-second delay can be life-threatening. You don't want anything to delay your ability to draw a gun, even if it's a gun holster.

You should consider using a holster that you can pull out easily whether sitting, standing, or in any position. Besides, a holster that can fit both left-handed and right-handed people is also an option worth considering.

Protects Your Handgun

Sweaty hands are inevitable. Besides, depending on the position you wear, the holster, more or less, will run on not only your clothes but also your body. In the above cases, a waterproof and soft leather case will give you a great experience. 

Common Holster Material 

In addition to considering the protection and flexibility of the holster, you can't help but take the time to learn the material that makes the holster.

Because of its durability, impact resistance, and feeling when using the leather case, most of it comes from the type of material that the manufacturer uses.

Leather

The first leather cases were all made from leather. It can be said that leather is the most classic material but still the best for making holsters. Some of the advantages of leather holsters include ease of adjustment, durability, and luxury. However, leather is not usually a material that can be available long in humid environments or extreme heat.
Besides, products made from natural leather are often higher than products with the same features.

Kydex

You will easily see soldiers and police using holsters made from Kydex because Kydex material is made of polymers, famous for its sturdiness and durability. Therefore, you can be assured of the product's longevity and its outstanding water and scratch resistance.
Besides, Kydex is a great material to make IWB leather cases. Because of the material’s breathability, the disadvantage of easily accumulating sweat, the strange smell of the IWB holster is no longer a concern.

Nylon

Nylon may not be as durable as Kydex but does not hug you like leather. However, Nylon is a good material to make holsters that allow you to draw a gun quickly. If you don't use guns very often, a reasonably priced nylon holster is more than enough.

Injection Molded Plastic

Nylon is already a fairly easy material to find, making cheap gun holsters. Then mass-produced Injection Molded Plastic brings lower cost but higher quality. The manufacturer will put molten plastic into the mold, after cooling down, the gun holster for life. However, you need to pay attention to the type of gun that matches the holster if you choose Injection Molded Plastic.

Hybrids

If leather is too expensive, Nylon is damaged quickly, and Injection Molded Plastic is too hard, then Hybrids will be the best choice to help overcome all of the above disadvantages. Hybrids are a combination of two or more of the above materials. The Hybrid's holster can hold the gun well and is also the most comfortable to use.
The vast majority of IWB holsters are hybrid holsters because of the comfort and sturdiness that the material provides.

Conclusion

In addition to the five suggestions above, there are many other options available to you. However, you should be aware that sometimes the best Glock 21 holsters can also make you unhappy. Because each person's needs, work, and usage is different.

To choose the best glock 21 holster, you should carefully read our reviews in the article to make the choice that best suits your requirements. 

We hope that you will find the best holster soon.
