IMI Defense RD3 Level 3 Red Dot Sight Holster for Glock

The IMI Defence RD3 Level 3 Red Dot Sight Holster for Glock is an advanced duty holster that combines maximum safety with a lightning-fast draw. This holster is designed for professionals, sport shooters and airsoft players who use a Glock with or without a red dot sight. Thanks to the patented Level 3 Retention System, the integrated protection for optics and the robust glass-fibre-reinforced polymer construction, the RD3 offers an exceptionally high level of safety and reliability.

This mid-ride holster is compatible with a wide range of Glock models and a broad selection of popular red-dot sights, making it a versatile choice for modern tactical gear.

Gepatenteerd Level 3 Retention System

At the heart of the RD3 is the innovative Level 3 Retention System. This system secures the firearm firmly in the holster and prevents accidental loss or unauthorised drawing.

Applying gentle pressure with the thumb, the following actions then take place simultaneously:

• The lock is being unlocked.
• The red dot’s protective cover opens automatically.
• The pistol can be drawn immediately.

Because all the movements take place in a single, fluid motion, the pulling action remains quick and intuitive.

Protection for your red dot sight

A key distinguishing feature of the RD3 is the integrated Optics Shroud.

This protective cap covers the fitted red dot sight when the pistol is stowed away and protects the sight from:

• Stof.
• Mud.
• Rain.
• Scratches.
• Punching.

When the pistol is drawn, the protective cover opens automatically, so that the sight is immediately accessible without any further action being required.

Also suitable without a red dot sight

Although the RD3 has been specially designed for pistols fitted with an optic, the holster also works perfectly well without a red dot sight fitted.

This is because the retention system engages directly with the pistol itself, rather than the sight. As a result, safety and functionality remain the same, regardless of whether you’re using an optic.

This makes the holster future-proof should you decide to fit a red dot sight at a later date.

Glass-fibre-reinforced polymer

The holster is made from fibreglass-reinforced polymer, a material known for its high strength and excellent wear resistance.

As a result, the RD3 is resistant to:

• Intensive daily use.
• Wear and tear.
• Scratches.
• Shocks.
• Tough tactical conditions.

The matt finish also reduces light reflections and helps to minimise unwanted glare.

Resistant to extreme temperatures

The IMI Defence RD3 continues to operate reliably in a wide range of weather conditions.

The structure can withstand temperatures of:

• -40°C
• Up to +150°C

This makes the holster suitable for use in virtually any environment.

Suitable for several Glock models

This model is designed for various Glock pistols, including:

• Glock 17 (Gen 3–5)
• Glock 19 (Gen 3–5)
• Glock 19X
• Glock 22 (Gen 1–4)
• Glock 23 (Gen 1–4)
• Glock 25
• Glock 28

• Glock 32
• Glock 45 (Gen 3–5)
• Glock 47

In addition, the holster is also compatible with:

• ZEV OZ9 V2 Elite
• ZEV OZ9 V2 Elite Hyper Comp

Always check that your specific configuration matches the compatibility list.

Compatible with popular red dot sights

The RD3 is compatible with a wide range of popular pistol optics, including models from:

• Trijicon (RMR, RCR)
• Leupold DeltaPoint Pro
• Sig Sauer Romeo series
• Aimpoint Acro C-2
• Aimpoint COA
• Bushnell RXS series
• Bushnell Advance Reflex Sight

Similar optics with corresponding dimensions will usually fit without any problems.

Adjustable fit

Any replica or firearm may have slight tolerances. That is why the RD3 offers a range of adjustment options.

For example, the holster is fitted with:

• Adjustable tension screw to prevent rattling.
• Barrel alignment pin.
• Interchangeable spacers for different stride lengths.

This ensures that the pistol remains securely and stably in the holster.

Mid-Ride configuration

Instead of a traditional drop leg, this holster is designed as a mid-ride.

This means you’ll benefit from:

• Greater comfort.
• Less restriction of movement.
• More compact equipment.
• Faster access to the pistol.

The non-slip leg strap supplied ensures that the holster remains secure even during vigorous movement.

Compatible with Safariland mounting systems

The RD3 is compatible with Safariland® mounting options, making it easy to integrate into existing tactical gear.

In addition, the strap loops supplied are suitable for:

• 1,5 inch duty belts.
• 1,75 inch duty belts.
• 2 inch duty belts.

This means the holster fits most professional belts.

Practical insights

More and more pistols are being fitted with a red dot sight, but many traditional holsters do not provide sufficient space or protection for them. The RD3 solves this problem with an integrated protective cover that shields the sight until you draw the pistol.

The combination of Level 3 retention, an intuitive release mechanism and extensive compatibility makes this holster particularly suitable for airsoft players, instructors, sport shooters and professionals who wish to combine maximum safety with a quick draw of their pistol.

Common mistakes

A common mistake is to assume that any Glock will automatically fit with any red dot sight. Always check both the Glock model and the dimensions of the mounted sight before choosing a holster.

You should also check the tension of the holster regularly and, once fitted, test that the retention system is working correctly before using it during a skirmish or training session.
