Discover how to select the perfect Glock 45 holster based on carry style, retention, light compatibility, and material. Compare IWB, OWB, and appendix options.

The Glock 45 is a favorite among law enforcement and civilian carriers alike, offering a perfect balance of full-size grip and compact slide. But pairing it with the right holster is just as important as the firearm itself. A holster that fits poorly can compromise comfort, concealment, and even safety. This guide will walk you through the key factors to consider when choosing a holster for your Glock 45, from carry style and retention to material and light compatibility.

Whether you're new to carrying or looking to upgrade your setup, understanding your needs is the first step. We'll break down the pros and cons of IWB, OWB, and appendix carry, discuss the importance of retention, and explain how to ensure your holster works with your accessories like weapon lights and optics. By the end, you'll have a clear idea of what to look for in a Glock 45 holster.

Carry Style: IWB vs OWB vs Appendix

Your preferred carry style is the most important factor in choosing a holster. Inside-the-waistband (IWB) holsters are popular for concealed carry because they tuck the firearm closer to your body, making it easier to hide under a T-shirt or jacket. For the Glock 45, an IWB holster like the Garage Sale The Rig - Fits Glock 34/17/19 Gen 2-6 offers a snug fit and adjustable retention, making it a versatile choice for everyday carry.

Outside-the-waistband (OWB) holsters are more comfortable for open carry or range use, as they sit on the hip and allow a smoother draw. They're also easier to access when wearing a duty belt. Appendix carry, which positions the holster at the front of your waistband, is favored for its quick draw and reduced printing, but it requires a holster with a low profile and often a claw or wedge to keep the grip tucked in. Consider your daily activities and clothing when deciding which style suits you best.

  • IWB: Best for concealed carry and everyday use.
  • OWB: Ideal for open carry, duty, and range days.
  • Appendix: Offers fast draw and minimal printing, but may require adjustment for comfort.

Retention Mechanisms: Passive vs Active

Retention is what keeps your Glock 45 secure in the holster. Passive retention relies on friction and the tension of the holster material to hold the firearm, while active retention uses a thumb break or hood that must be released before drawing. For most civilian carriers, passive retention is sufficient, especially with a quality kydex holster that has adjustable tension. The Blade Tech Tek-Mount Safariland Adapter can be used to mount certain holsters to a belt or platform, but it's important to ensure your holster has the right retention for your needs.

If you're in law enforcement or open carry, you might prefer active retention for added security against someone trying to grab your weapon. However, active retention can slow down your draw if you're not trained. For concealed carry, a holster with adjustable passive retention, like the Tek-Lok system, allows you to fine-tune the tension to your preference. Test your holster by drawing your firearm and ensuring it doesn't move when you run or bend over.

  • Passive retention: Friction-based, adjustable with screws or bolts.
  • Active retention: Includes thumb breaks or hoods for extra security.
  • Adjustable retention is key for a personalized fit.

Material: Kydex vs Leather vs Hybrid

The material of your holster affects durability, comfort, and retention. Kydex is a rigid thermoplastic that offers excellent retention and a positive 'click' when the firearm is seated. It's also resistant to moisture and easy to maintain, making it a popular choice for Glock 45 owners. A kydex holster like the Quick Ship - GT3 - OWB Rifle Magazine Carrier is a good example of the durability and reliability of kydex for magazine carriers, and similar principles apply to holsters.

Leather holsters are comfortable and mold to your body over time, but they can soften and lose retention, and they may not be ideal for use with weapon lights due to the added bulk. Hybrid holsters combine a leather backing with a kydex shell, offering comfort and retention. When choosing a material, consider your climate, how often you train, and whether you need a holster that can handle a weapon light. Kydex is generally the best all-around choice for a Glock 45, especially if you plan to use a light like the TLR7 Sub - For Glock.

  • Kydex: Durable, great retention, low maintenance.
  • Leather: Comfortable, molds to body, but can lose retention.
  • Hybrid: Combines comfort and retention, but may be bulkier.

Light and Optic Compatibility

Many Glock 45 owners mount a weapon light or red dot optic for enhanced performance. If you plan to use a light, you'll need a holster specifically designed to accommodate it. The TLR7 Sub - For Glock is a compact light that fits the Glock 45, and there are holsters that are cut for this light. Similarly, if you have an optic, you'll need a holster with an optic cut to avoid interference. The Garage Sale The Rig - Fits Glock 34/17/19 Gen 2-6 is an example of a holster that can be ordered with an optic cut, ensuring your red dot sits securely.

When selecting a holster, check the manufacturer's specifications to ensure it supports your specific light and optic models. A holster that is not cut properly can cause damage to your gear or affect your draw. Also, consider whether you want a holster that can be used with or without a light, as some models offer modular designs. The Blade Tech Tek-Mount Safariland Adapter can be used to adapt certain holsters to different mounting systems, but it's essential to start with a holster that fits your firearm and accessories correctly.

  • Ensure the holster has a cut for your weapon light model.
  • Optic cuts are necessary for red dot sights.
  • Modular holsters offer flexibility for different setups.

Comfort and Concealment Features

Comfort is crucial for daily carry, as you'll likely wear your holster for hours. Look for features like padded backings, adjustable cant, and claw or wing attachments that help tuck the grip closer to your body. For appendix carry, a claw or wedge can significantly improve concealment and comfort. The Fast Draw is a concept that emphasizes speed and efficiency, and your holster should facilitate a smooth draw without sacrificing comfort.

Additionally, consider the ride height and cant of the holster. A higher ride can make drawing easier, while a forward cant can help with concealment. Many kydex holsters allow you to adjust these features with different mounting clips or loops. The Tek-Lok is a popular belt attachment that allows for easy on/off and adjustable positioning. Test different settings to find what works best for your body type and clothing.

  • Look for adjustable cant and ride height.
  • Claws or wedges improve concealment for appendix carry.
  • Padded backings enhance comfort for all-day wear.

Choosing the right holster for your Glock 45 is a personal decision that depends on your carry style, retention needs, material preferences, and accessory compatibility. By evaluating these factors, you can find a holster that offers safety, comfort, and performance. Whether you prefer a kydex IWB for concealed carry or an OWB for open carry, remember to prioritize quality and fit.
