How to Choose the Right Holster for Your Holosun 507 COMP

Adding a red dot sight like the Holosun 507 COMP to your pistol is a game-changer for speed and accuracy. But to carry that setup effectively, you need a holster that fits both your gun and the optic. Not all holsters are designed to accommodate red dot sights, and choosing the wrong one can lead to poor retention, damage to your optic, or even safety issues.

In this guide, we'll walk you through the key factors to consider when selecting a holster for your Holosun 507 COMP. From optic cutouts to light compatibility and retention, we'll help you make an informed decision that matches your carry style and gear. Whether you prefer inside-the-waistband (IWB) or outside-the-waistband (OWB) carry, we've got you covered.

Why Your Holster Needs an Optic Cut

A red dot sight like the Holosun 507 COMP sits above the slide, adding extra height that a standard holster cannot accommodate. An optic cut holster is specifically designed with a channel or cutout that allows the sight to pass through without snagging or causing excessive pressure. This ensures a smooth draw and reholster while protecting your optic from scratches and impacts.

When shopping for a holster for your Holosun 507 COMP, always check that the holster explicitly states it is compatible with red dot sights. Many quality kydex holsters come with an optic cut as standard, but some budget options may not. Look for a holster that covers the optic but leaves enough room for the lens and housing to sit freely.

• Ensure the holster has a cutout that matches the size of the Holosun 507 COMP.
• Check that the retention is not compromised by the optic cut – the holster should still hold the gun securely.

Light Compatibility: Do You Carry a Weapon Light?

If you plan to attach a weapon light to your pistol, you'll need a light-compatible holster. These holsters are designed with a molded channel that accommodates the light's shape, providing retention on the light rather than the trigger guard. This design ensures a secure fit and allows for proper draw and reholstering even with a bulky light attached.

For example, if you're using a Streamlight TLR-7-X or TLR-1 HL-X, you'll need a holster that is specifically made for that light model. Many holster manufacturers offer options for popular lights, and some even design universal light-bearing holsters. When choosing a holster for your Holosun 507 COMP with a light, make sure the holster is compatible with both your pistol and light combination.

• Always verify that the holster is compatible with your specific light model, not just 'most lights'.
• Consider the 'Quick Ship - The Rig - Light Compatible' if you need a versatile holster that fits multiple light-bearing pistols.

IWB vs OWB: Which Carry Style Suits You?

Your carry style plays a significant role in holster selection. Inside-the-waistband (IWB) holsters are popular for concealed carry because they tuck the gun close to your body, making it easier to hide under a shirt. For a red dot-equipped pistol like the Holosun 507 COMP, an IWB holster needs to have a low-profile design that minimizes printing while still providing a comfortable and secure fit.

Outside-the-waistband (OWB) holsters are often preferred for open carry, competition, or duty use. They offer a more natural draw angle and are generally more comfortable for all-day wear. When choosing an OWB holster for your Holosun 507 COMP, look for one with adjustable retention and a sturdy belt attachment. Some OWB holsters also come with a paddle or belt loop option for added versatility.

• For IWB, consider a holster with a claw or wing attachment to help tuck the grip closer to your body.
• For OWB, look for a holster with adjustable cant and retention to customize your draw.

Retention and Security: What to Look For

Retention is how well the holster holds your pistol in place. For a red dot sight, it's crucial that the holster provides a secure fit without putting excessive pressure on the optic. Most kydex holsters offer adjustable retention via screws, allowing you to fine-tune the tension. You want a holster that holds the gun firmly but still allows a smooth draw.

Some holsters come with active retention mechanisms, such as thumb breaks or hoods, which provide an extra layer of security. While these are more common in duty holsters, they can be beneficial for anyone concerned about accidental dislodging. When testing a holster for your Holosun 507 COMP, ensure the gun clicks in securely and does not wobble or shift during movement.

• Test the retention by holstering the gun and shaking it upside down – it should stay in place.
• Adjust the retention screws gradually to avoid over-tightening, which can damage the optic or make drawing difficult.

Material and Build Quality

Kydex is the most common material for red dot compatible holsters because it is rigid, durable, and can be precisely molded to fit specific gun and optic combinations. It also holds its shape over time, ensuring consistent retention. Some holsters use a hybrid design with a leather backing for comfort, but make sure the leather doesn't interfere with the optic cutout.

When choosing a holster for your Holosun 507 COMP, inspect the edges and seams for any rough spots that could scratch your firearm or optic. A quality holster should have smooth, rounded edges and a clean finish. Additionally, consider the thickness of the kydex – thicker material offers more durability but may add bulk.

• Look for holsters made from .08-inch kydex for a good balance of durability and comfort.
• Avoid holsters with sharp edges that could snag on clothing or damage the optic.

Choosing the right holster for your Holosun 507 COMP is about balancing fit, comfort, and functionality. Whether you need a light-compatible option like the 'Quick Ship - The Rig - Light Compatible' or a simple IWB holster, always prioritize a holster with an optic cut and proper retention. Take your time to research and test different options to find the one that works best for your carry style and gear. Your Holosun 507 COMP deserves a holster that keeps it secure and ready.
