Buying Guide
Choosing the right holster depends on several factors, including your carry style, body type, and personal preferences. Here are a few things to consider:
- Carry Style: Do you prefer IWB, OWB, appendix, or shoulder carry? Each style has its own advantages and disadvantages. IWB is generally better for concealment, while OWB is often more comfortable for open carry.
- Material: Kydex is durable and offers excellent retention, but can be less comfortable than leather. Leather is comfortable and molds to your body over time, but it requires more maintenance. Hybrid holsters combine the best of both worlds.
- Retention: Passive retention relies on friction to hold the gun in place. Active retention uses a locking mechanism to secure the firearm. Active retention holsters are generally more secure.
- Adjustability: Look for holsters that offer adjustable cant and ride height. This will allow you to customize the holster to your body and carry style.
- Comfort: Consider how comfortable the holster will be for all-day wear. Look for features like padded backing, breathable materials, and smooth edges.
FAQs
Q: What is the best way to conceal a Glock 21?
A: IWB holsters are generally the best for concealing a Glock 21, especially those made from Kydex or hybrid materials. Appendix carry can also be a good option for some people.
Q: How do I adjust the retention on my Kydex holster?
A: Most Kydex holsters have an adjustable retention screw. Tightening the screw increases retention, while loosening it decreases retention. Make small adjustments and test the draw until you find the right balance.
Q: What is the difference between passive and active retention?
A: Passive retention relies on friction to hold the gun in place, while active retention uses a locking mechanism. Active retention holsters are generally more secure, but they require more practice to draw smoothly.
Q: Can I use the same holster for different guns?
A: Generally, no. Holsters are designed to fit specific firearms. Using the wrong holster can be unsafe and may damage your gun.
