Buying Guide: Holster for Glock 20 with Light

Understanding the Glock 20 with Light

When I first decided to purchase a holster for my Glock 20 equipped with a tactical light, I quickly realized that this was not a straightforward task. The Glock 20 is a powerful handgun, and adding a light changes its profile and weight distribution. It’s essential to understand how these factors affect the type of holster that will work best for me.

Types of Holsters

As I explored my options, I found that holsters come in various styles, including OWB (Outside the Waistband), IWB (Inside the Waistband), and shoulder holsters. OWB holsters are great for open carry, while IWB holsters provide more concealment. Shoulder holsters are also an option, especially for those who prefer to carry in a more discreet manner. I had to consider my personal needs and how I intended to carry my Glock 20 with a light.

Material Considerations

The material of the holster plays a significant role in comfort and durability. I noticed that holsters are often made from leather, Kydex, or nylon. Leather offers a classic feel and comfort, while Kydex provides a secure fit and fast draw. Nylon is often lightweight and affordable, but may lack the rigidity I wanted. I had to weigh the pros and cons based on my lifestyle and preferences.

Retention Features

Retention is crucial for me when it comes to holsters. I wanted to ensure that my Glock 20 with light would stay securely in place while still allowing for a quick draw. I found holsters with passive retention features, such as friction fit, and active retention systems that use buttons or straps. Evaluating these features helped me determine which would best suit my needs for safety and accessibility.

Fit for Accessories

Since my Glock 20 has a tactical light, I needed to ensure that the holster I chose was designed specifically for this combination. I learned that not all holsters accommodate lights, and this was a critical factor in my search. I had to look for holsters specifically labeled as compatible with both the Glock 20 and the light I was using.

Comfort and Usability

Comfort is paramount, especially if I plan to carry for extended periods. I took the time to consider factors like holster weight, padding, and the overall design that would fit my body type. Additionally, I evaluated the ease of access and whether the holster allowed for a smooth draw. Trying on different holsters helped me find the right balance between comfort and functionality.

Price Range

Finally, I had to establish a budget for my holster purchase. Prices can vary widely based on material, brand, and features. I found it helpful to set a price range beforehand, allowing me to focus on options that met my needs without breaking the bank. I was careful to consider the value offered by each holster in relation to its price.

finding the right holster for my Glock 20 with a light required thorough research and consideration of multiple factors. By understanding the type of holster, material, retention features, compatibility with accessories, comfort, and price, I felt well-equipped to make an informed decision. I recommend taking the time to explore and test various options to find the perfect fit for your needs.
