Why a Glock 21 Gen 5 Holster is Necessary
From my experience, having a dedicated holster for my Glock 21 Gen 5 is absolutely essential. First, it ensures that my firearm is securely held in place, preventing any accidental drops or shifts that could compromise safety. Without a proper holster, I’d constantly worry about the gun moving around or even falling out during daily activities.
Another reason I find a holster necessary is quick and reliable access. When I need to draw my Glock 21 Gen 5, having it properly positioned in a holster means I can do so smoothly and confidently. This is crucial, especially in situations where every second counts. Plus, a good holster protects the gun from dirt, sweat, and wear, preserving its condition over time.
Finally, comfort plays a big role. Carrying my Glock 21 Gen 5 in a holster designed specifically for it makes a huge difference in how it feels throughout the day.

My Buying Guides on Glock 21 Gen 5 Holster
When I decided to get a holster for my Glock 21 Gen 5, I quickly realized there are a lot of options out there. To help you find the best fit for your needs, I’m sharing what I learned through my experience. Here’s what you should consider before making a purchase.
1. Understanding Your Carry Style
The first thing I thought about was how I planned to carry my Glock 21 Gen 5. Are you going for concealed carry, open carry, or range use? I found that different holsters suit different carry styles:
- Inside-the-Waistband (IWB): Great for concealment but can be less comfortable for long wear.
- Outside-the-Waistband (OWB): Easier access and comfort, but less concealable.
- Shoulder Holsters: Useful if you want to alternate carry positions.
- Pocket or Ankle Holsters: Not usually ideal for the size of Glock 21, but worth noting.
Knowing my preferred carry style helped narrow down my options significantly.
2. Material Matters: Leather, Kydex, or Hybrid?
I had to choose between leather, Kydex, or a hybrid holster. Each material has pros and cons:
- Leather: Feels classic and molds to the gun over time. It’s comfortable but can wear out faster and is less resistant to moisture.
- Kydex: Durable, rigid, and holds shape perfectly. Offers excellent retention but can be noisy when drawing or holstering.
- Hybrid: Combines leather backing with a Kydex shell. Offers comfort and retention but can be bulkier.
I personally went with a Kydex holster because I wanted maximum retention and a quick draw.
3. Retention and Security Features
Retention is critical with a powerful handgun like the Glock 21 Gen 5. I looked for holsters that offer adjustable retention screws or locking mechanisms to ensure the gun doesn’t move around or fall out during activity. Some holsters also have thumb breaks or retention hoods for added security, which can be a good option if you want extra peace of mind.
4. Comfort and Fit
Comfort was a big factor for me since I planned to carry for extended periods. I checked user reviews on how the holster felt against the body and whether it caused any irritation. Also, I made sure the holster was specifically molded for the Glock 21 Gen 5 to ensure a perfect fit without wiggle room.
5. Ease of Draw and Re-holstering
I tested how smoothly I could draw and re-holster the Glock. A good holster should allow a quick, natural draw without fighting the retention system, but also make re-holstering safe and easy. If possible, try the holster before buying or watch detailed videos demonstrating the draw.
6. Concealability and Profile
Since the Glock 21 is a full-size handgun, concealability can be a challenge. I looked for holsters with a slim profile and options for adjustable cant (angle) to help tuck the gun closer to my body. Holsters with sweat guards also helped keep the gun from printing through clothing.
7. Price and Brand Reputation
Holsters can range from budget-friendly to premium prices. I balanced cost with quality and opted for brands known for durability and customer service. Investing a bit more upfront saved me from replacing holsters often.
8. Additional Features
Some holsters come with extra features like:
- Belt loops or clips: For different belt widths and carry positions.
- Modular designs: Allow switching between carry styles.
- Adjustable cant and ride height: For personalized comfort.
These extras can enhance your carry experience.
Conclusion
Buying a holster for my Glock 21 Gen 5 was about balancing comfort, security, and concealability. By considering my carry style, material preference, and holster features, I found one that fits my lifestyle perfectly. I recommend you do the same—think about how you’ll carry, what’s comfortable for you, and which features matter most. That way, you’ll enjoy carrying your Glock safely and confidently every day.
