What To Consider When Buying Best Glock 21 Accessories?

All gun owners seem to be on a never-ending search for Glock 21 Accessories.  There are so many great Glock accessories out there in the world, it seems impossible to go wrong. Here are the best Glock 21 accessories that you’ll want to check out right away.

Holster

This is probably the most important accessory because it is what holds your weapon and protects it from sweat and the elements. A good holster should be designed for an easy draw and reholstering should hold your pistol securely without letting it get loose. A good holster should have a safe belt loop or clip, should protect the trigger guard from being accessed, and it should be made of durable materials that are comfortable and effective.

Magazine Pouch

A magazine will fit into a Glock 21, but having a separate accessory that attaches to the belt and holds the spare mag is much more convenient as it allows you to quickly access it and change it if necessary.

Laser Sight

This is probably one of the best accessories because it will help you aim and fire more accurately in low light or dark conditions, such as when you’re in a fight.

Grips

The grip on a Glock 21 is pretty big and it may feel uncomfortable for some people because the frame doesn’t have any sort of grip attached to it as most pistols do. You can get rubber grips that easily snap onto the frame and cover it. They make your hand feel like it’s gripping something, but they also give you more control over where the handle is avoiding slide bites.

Extended Magazine Release

The button for releasing a Glock 21 magazine can be pretty small and difficult to press down whereas an extended version gives you more leverage for easily releasing the magazine.

Ammunition Holder

You can get a magazine pouch that holds your extra magazines or you can get one that has pockets for holding different types of ammunition so you don’t have to carry around boxes of bullets. It’s just a small, separate accessory that is used for carrying ammo instead of magazines.

Ammunition

This is something that you should probably get in bulk. The more ammo you have, the better because it means that if you ever run out and need to reload, then at least there’s enough extra ammunition for you to keep fighting without having to pause and find more bullets in your pockets or in a pouch which could be too late.

Glock 21 Muzzle Brake

Although not entirely necessary, it’s a good accessory to get because it keeps the gun stable so you can fire it without shaking around or wobbling. It also gives your fingers more room for holding onto the gun instead of having the front sight pressed against your hand.

Lubricant

You should always clean and lubricate your weapon because it prevents rust, ensures smooth operation, and maintains the life of the gun.

Sight Attachment

Some pistols come with removable front sights while others require you to buy them separately, but this is an accessory that will make it easier to aim.

Grip Attachment

A pistol’s grip may feel uncomfortable or slippery, and to make it easier to hold onto and grip with your fingers, you can attach a rubberized pad for more control over where the gun is.

Tactical Light

Some Glocks come equipped with removable lights whereas others require you to buy them separately. This is another accessory that will help identify threats when there’s not enough light to see, but you don’t have a flashlight or any other sort of illumination device.

FAQs

Slide bite occurs when you fire your weapon and the slide comes back to rest against your hand, irritating the skin, or cuts. It can be prevented by using a muzzle brake to give more space between where the gun rests in your hand and where you place your hands when firing.

Cleaning and lubricating your weapon maintains its life and ensures smooth operation so you don’t have to worry about your gun jamming or breaking.

There are many reasons why you might need one, but a tactical light comes in handy if you don’t have a flashlight that allows you to see your surroundings if it’s dark, or identify a threat that you can’t see. It also could be used as an intimidation tactic because it makes the gun easier to see from a distance.

Having a larger button on the grip of your gun which you can press with your thumb will make it easier for you to release a magazine when necessary so you don’t have to go digging around in your pockets or pull out a pouch.

 A muzzle brake reduces the amount of recoil you feel when firing your weapon by venting gases to the side. These small ports redirect the gas so it acts as a sort of counterforce against the recoil, allowing for faster recovery time between shots. Another advantage is that they reduce muzzle climb, but the main purpose is to reduce recoil.

Conclusion

The Glock 21 is a versatile weapon, but you need to make sure that it’s well-equipped for the task at hand. Think about what your needs are and how they might change during different situations or environments. If you’re looking for extra ammo storage, consider an ammunition pouch as well as a holster to keep your gun safe from theft while carrying around less weight in utility pouches on belt loops.
