The Ultimate Guide to Choosing an IWB Holster for Your Sig P365

The Sig P365 is a popular choice for concealed carry. Because of its small size, it fits perfectly inside the waistband (IWB). However, you need the right holster to stay comfortable and safe. This guide helps you pick the best gear for your firearm.

Key Features to Look For

First, prioritize retention. A good holster holds your gun securely so it does not fall out. Look for an adjustable retention screw. This allows you to tighten or loosen the fit to your liking.

Second, check the trigger guard coverage. A safe holster must completely cover the trigger. This prevents accidental discharges while the gun sits in your waistband.

Third, look for a claw or wing attachment. This simple piece of plastic pushes against your belt. It rotates the grip of the gun toward your body. This reduces “printing,” which is when the outline of the gun shows through your shirt.

Important Materials

Most IWB holsters use one of two materials: Kydex or leather.

  • Kydex: This is a hard, molded plastic. It keeps its shape perfectly. Kydex holsters offer a fast draw and a loud “click” when the gun is secure. They are very durable and easy to clean.
  • Leather: Leather is soft and conforms to your body over time. Many people find leather more comfortable for long days. However, leather can lose its shape after years of use.
  • Hybrid: Many owners choose a hybrid design. These use a leather backing against your skin and a Kydex shell for the gun. This offers the best of both worlds.

Factors That Affect Quality

Quality often comes down to the belt clip. A flimsy clip will allow the holster to move or pull out when you draw your weapon. Look for steel clips or reinforced polymer clips with a strong hook.

Another factor is the ride height and cant. The “cant” is the angle of the gun. If you can adjust the angle, you can find the most comfortable position for your specific body type. A holster with multiple holes for the clip allows for these adjustments.

User Experience and Use Cases

Think about how you carry. If you carry at the “appendix” position (front of your waist), you need a holster with a smooth finish. Sharp edges will dig into your skin when you sit down. If you carry at the “strong side” (near your hip), you might prefer a holster with a slightly higher sweat guard. A sweat guard keeps the metal of the gun from touching your skin, which prevents rust and irritation.

10 Frequently Asked Questions

Q: Can I use the same holster for a P365XL?

A: Not always. The P365XL has a longer slide. Check if your holster has an “open muzzle” design. If it does, the longer gun might fit through the bottom.

Q: Is Kydex better than leather?

A: Kydex is generally safer because it maintains its shape. Leather is often more comfortable for beginners.

Q: What is a “sweat guard”?

A: It is a piece of material that extends up between your body and the gun slide.

Q: Do I need a belt with my IWB holster?

A: Yes. A stiff gun belt is essential to support the weight of the holster.

Q: How do I adjust the retention?

A: Most holsters have a screw near the trigger guard. Turn it clockwise to tighten and counter-clockwise to loosen.

Q: Will the holster scratch my gun?

A: Kydex can cause slight wear on the finish of your gun over time. This is normal for a carry tool.

Q: What is “printing”?

A: Printing is when the shape of your gun is visible through your clothing.

Q: Can I wash my holster?

A: Yes. Kydex holsters can be washed with mild soap and water.

Q: Should I carry with one in the chamber?

A: If your holster covers the trigger completely and you have practiced, many carriers choose to do so.

Q: Where is the best place to wear an IWB holster?

A: Appendix carry (front) and 4 o’clock (hip) are the most popular positions.
