What Is the Best Concealed Carry Holster for a Glock 20?

For concealing a Glock 20, the best option is a tuckable IWB Kydex holster worn at appendix or 4 o'clock with a claw and a stiff gun belt. The large frame and 4.61 inch barrel make ride height and cant the deciding factors. An OWB paddle suits woods carry and range use.

Is the Glock 20 Hard to Conceal?

Yes, the Glock 20 is one of the harder guns to conceal. It is a full size, large frame gun at roughly 8.07 inches long and 1.34 inches wide, and it is the grip that prints rather than the slide. A tuckable IWB holster with a claw, high ride height and a rigid belt makes the biggest difference.

Can the Glock 20 Be Concealed Carried?

Yes, though it takes commitment. A full size 10mm conceals with a tuckable IWB holster, a claw, high ride height and a proper gun belt, worn under an untucked shirt or a jacket. Many owners carry it openly in the woods and switch to the smaller Glock 29 for daily concealment.

Do These Holsters Fit the Glock 20 Gen 5?

Yes. Every Rounded Gear Glock 20 holster fits the Glock 20 Gen 2 through Gen 5, including the V models and the Glock 20 MOS, and the same molds fit the Glock 21. Each holster is cut to clear a red dot, so an optic-equipped MOS carries with the optic mounted. They are not cut for weapon lights.

Can a Glock 20 Fit in a Glock 21 Holster?

Usually yes. The Glock 20 and Glock 21 share the same large frame and slide dimensions, so most holsters molded for one hold the other, and many makers list a single Glock 20/21 option. Retention can vary slightly between generations, so confirm the shell covers the trigger guard completely before carrying.

Can a Glock 20 Fit in a Glock 17 Holster?

No. The Glock 20 is built on Glock's large frame while the Glock 17 uses the standard frame, so the 20 is wider and taller through the slide and will not seat properly in a Glock 17 shell. The Glock 21 is the correct cross-fit, because it shares that same large frame.

Is the Glock 20 the Best 10mm?

The Glock 20 is the most widely recommended all around 10mm and has the deepest holster and parts support in the caliber, with 15+1 capacity and a Gen 5 MOS version added in 2025. Best depends on the job, though: the Glock 29 conceals far better and the Glock 40 suits hunting and longer shots.

Carrying a 10mm Glock 20

The Glock 20 is a full-size, large-frame gun, about 8 inches long, and the grip is what prints. To conceal it, most owners run the tuckable or the IWB with a claw on a stiff gun belt, under an untucked shirt or a jacket. For the woods, hunting or the range, the paddle and belt loop OWB carry it outside the waistband. We don’t make a light-bearing Glock 20 holster, so these won’t take a gun with a light mounted.

Glock 20 Holster Guide

Find the Best Glock 20 Holster for 10mm Carry and Range Use

Shop Glock 20 holsters built for 10mm carry, range training, and secure everyday use. The Glock 20 is a full-size 10mm pistol with more weight and recoil than many compact carry guns, so the right holster should provide stable retention, full trigger guard coverage, and a secure belt-mounted setup.

Rounded Gear Glock 20 holsters are precision-molded from durable Kydex with adjustable retention, full trigger guard coverage, and the audible Posi-Click® fit that confirms your firearm is seated. Choose IWB or appendix carry when concealment matters, OWB for range and outdoor use, and verify fitment if your Glock 20 has MOS optics, lights, threaded barrels, or suppressor-height sights.

Glock 20 Holster Buyer’s Guide

What Is the Best Glock 20 Holster for Concealed Carry?

The best Glock 20 holster for concealed carry is usually an IWB or appendix IWB holster with strong retention and a stable belt attachment. Because the Glock 20 is a full-size 10mm pistol, concealment is easier with a rigid Kydex shell, a quality gun belt, and a holster that keeps the pistol close to the body.

Choose IWB: Best all-around option when you want to conceal a Glock 20.
Choose appendix with claw: Best for reducing grip printing and improving front-of-body access.
Choose tuckable IWB: Best when you need to conceal with a tucked shirt.
Choose OWB: Best for range use, hiking, outdoor carry, or open carry.

Should You Choose an IWB or OWB Glock 20 Holster?

IWB and OWB Glock 20 holsters solve different carry needs. IWB holsters sit inside the waistband and are better for concealment. OWB holsters sit outside the waistband and are often more comfortable for a full-size 10mm pistol during training, range use, or outdoor carry.

When to Choose a Glock 20 IWB Holster

Choose IWB if concealment is your priority. A Glock 20 IWB holster keeps the pistol closer to the body and supports a repeatable draw from concealment.

When to Choose a Glock 20 OWB Holster

Choose OWB if comfort, range use, hiking, or open carry matters most. A paddle holster is convenient, while a belt loop holster creates a more secure belt-mounted setup.

Does a Glock 20 Gen 5, MOS, or Accessory Setup Need a Different Holster?

Glock 20 holster compatibility depends on generation, slide configuration, sight height, optics, lights, threaded barrels, and compensators. If you carry a Glock 20 Gen 5 MOS or any optic-ready setup, choose a holster that specifically supports that configuration.

Always confirm product fitment before ordering, especially if your Glock 20 includes a red dot, weapon light, suppressor-height sights, or other accessories.

What Is the Best Glock 20 Holster for Outdoor and Range Carry?

The Glock 20 is popular for range, field, and outdoor use because of its 10mm chambering. For these use cases, many owners prefer an OWB Glock 20 holster for easier access, comfort, and stability over longer wear periods.

An OWB paddle holster is convenient for quick removal, while an OWB belt loop holster provides a more locked-in feel for hiking, range training, and extended carry.

Why Choose a Kydex Glock 20 Holster?

Kydex is a strong holster material for the Glock 20 because it is rigid, durable, and molded to the firearm. A quality Kydex holster helps protect the trigger guard, maintain its shape, resist moisture, and support safer re-holstering.

Rounded Gear Glock 20 Kydex holsters are designed for practical carry with adjustable retention, secure fitment, and a lifetime guarantee.
