Why I Believe a Holster for Glock 21 with Light is a Necessity

As a gun owner, I take my responsibility of safe and responsible carrying very seriously. That’s why I firmly believe that having a holster specifically designed for my Glock 21 with a light attachment is an absolute necessity.

First and foremost, it provides crucial protection for both myself and those around me. The built-in trigger guard on the holster ensures that my firearm is securely held in place, minimizing the risk of accidental discharge. This is especially important when carrying a firearm with an attached light, as the added weight can sometimes cause a looser fit in traditional holsters.

Moreover, using a holster designed for my specific firearm and light combo allows for quick and easy access in case of an emergency. I don’t have to fumble around or readjust my grip to get to my gun, which could result in precious seconds lost during a critical situation.

In addition, using a holster made specifically for my Glock 21 with light also ensures proper retention and comfort. The fit is tailored to the exact dimensions of my gun and light, providing a snug yet comfortable fit against my body. This not only makes carrying more comfortable but also prevents any shifting or movement of the

My Buying Guide on ‘Holster For Glock 21 With Light’

I have been a proud owner of a Glock 21 with a light attachment for quite some time now. And let me tell you, finding the perfect holster that fits my firearm and light has been quite a challenge. After extensive research and personal experience, I have compiled this buying guide to help fellow gun enthusiasts in their search for the ideal holster for their Glock 21 with light.

Types of Holsters

The first step in finding the right holster is understanding the different types available in the market. The most common ones are:

  • Inside-the-waistband (IWB) holsters – These are worn inside the waistband and provide good concealment.
  • Outside-the-waistband (OWB) holsters – These are worn outside the waistband and offer easy access to the firearm.
  • Shoulder holsters – These are worn over the shoulder and provide good comfort for all-day wear.
  • Ankle holsters – These are worn around the ankle and offer excellent concealment.

For my Glock 21 with light, I prefer an OWB holster as it allows for quick access to my firearm and also provides good retention.

Fitting and Compatibility

When looking for a holster, it is crucial to ensure that it fits your gun perfectly. For Glock 21 with light, you need to make sure that the holster is compatible with both your firearm model and its attached light. Some holsters may not be designed to accommodate lights, so it’s essential to double-check before making a purchase.

I made this mistake once when I bought a generic OWB holster that claimed to fit any Glock model. But when I received it, I realized it did not have enough space for my light attachment, making it useless for me.

Retention

Retaining your firearm securely in your holster is crucial for safety reasons. You don’t want your gun falling out or getting easily snatched from its place. When purchasing a holster, make sure it has adjustable retention to fit your preferred level of security. Some holsters use retention screws while others use adjustable straps or locks. Find one that works best for you.

Comfort and Concealment

If you plan on carrying your Glock 21 with light daily, then comfort and concealment should be top priorities when choosing a holster. Look for features like padded backings or sweat guards that prevent discomfort while wearing the holster against your skin. Also, consider factors like weight distribution, cant angle, and how well it conceals under clothing.

Budget

Holsters come in various price ranges depending on their quality and features. It’s essential to set a budget before starting your search as you don’t want to overspend on something unnecessary or compromise on quality just because of a low budget. It’s always better to invest in a high-quality holster that will last longer rather than buying cheap ones frequently.

Brand Reputation

Last but not least, consider the brand reputation when purchasing a holster for your Glock 21 with light. It’s always safer to go with well-known brands that have positive reviews from other gun owners rather than risking buying from an unknown brand with no track record.

I hope this buying guide helps you find the perfect holster for your Glock 21 with light just like it did for me! Happy shopping!
