IMI Defense RDL3 Level 3 Light and Red Dot Sight Holster for Glock

The IMI Defence RDL3 Level 3 Light and Red Dot Sight Holster for Glock is a professional duty holster specially designed for modern Glock pistols fitted with a weapon light, red dot sight or both. Thanks to the patented Level 3 Retention System, the integrated protection for optics and support for various tactical lights, this holster offers maximum security without compromising on speed.

The RDL3 is made from fibreglass-reinforced polymer and is designed for intensive professional use. Whether you’re involved in airsoft, shooting sports or tactical training, this holster offers a reliable solution for any user working with a fully equipped Glock.

Designed for pistols fitted with both a weapon light and a red dot sight

Whilst many holsters are designed exclusively for a red dot sight or, conversely, only for a torch, the RDL3 is designed to accommodate both accessories without any problems.

As a result, this holster is suitable for modern set-ups in which a Glock is fitted with:

• A red dot sight.
• A tactical weapon light.
• A combination of both.
• Or no accessories at all.

As the retention system locks directly onto the pistol, the operation remains the same regardless of the configuration chosen.

Gepatenteerd Level 3 Retention System

The safety of the pistol is central to the design of the RDL3.

The patented Level 3 Retention System prevents the firearm from being removed from the holster unintentionally, whilst ensuring it remains immediately accessible when needed.

With a single natural movement of the thumb, the following happen simultaneously:

• The Level 3 lock is being unlocked.
• The red dot’s protective cover opens automatically.
• The pistol is released immediately, allowing for a smooth draw.

As a result, the holster combines maximum safety with quick and intuitive handling.

Protective cap for your red dot sight

A vulnerable component of modern pistols is the mounted sight.

That is why the RDL3 features an integrated Optics Shroud that protects the red dot from:

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

When you draw the pistol, this protective cover flips open automatically, allowing you to use your sights straight away without any further action.

Compatible with weapon lights

The distinguishing feature of the RDL3 is its Light Bearing Capability.

This version offers enough space for a range of popular tactical torches, meaning you don’t have to modify your Glock or remove any accessories before you can carry it safely.

Always check beforehand whether your particular lamp fits within the dimensions for which the holster is designed.

Glass-fibre-reinforced polymer

The RDL3 is made from glass-fibre-reinforced polymer, a material known for its excellent combination of strength and durability.

The benefits include:

• High impact resistance.
• Suitable for intensive use.
• Scratch-resistant matt finish.
• Less light reflection.

This ensures that the holster continues to function reliably, even under demanding conditions.

Resistant to extreme temperatures

The structure retains its shape even at extreme temperatures.

Temperature range:

• -40°C
• Up to +150°C

This makes the holster suitable for use in a wide range of weather conditions and climate zones.

Suitable for several Glock models

This version is designed for, amongst other things:

• 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 31
• Glock 32
• Glock 45 (Gen 3–5)
• Glock 47

In addition, the holster is compatible with:

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

Always check that your specific configuration matches the manufacturer’s compatibility information.

Adjustable fit

Any replica or pistol may have minimal tolerances.

That is why the RDL3 offers a range of settings:

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

This ensures the holster fits your setup perfectly.

Mid-Ride design

The RDL3 is supplied as a mid-ride holster, making it more comfortable to wear than traditional drop-leg systems.

The advantages of this are:

• More compact equipment.
• Greater freedom of movement.
• Faster pulling motion.
• Less strain on the leg.

For extra stability, an non-slip leg strap is included to prevent the holster from slipping during vigorous movements.

Compatible with Safariland® mounting systems

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

In addition, the strap fastenings are suitable for:

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

This makes the RDL3 easy to combine with most tactical belts.

Practical insights

An increasing number of modern Glock configurations are fitted with both a red dot sight and a tactical light. Many traditional holsters do not provide enough space for both, or require one of the two accessories to be removed.

The IMI Defence RDL3 completely eliminates this problem. Thanks to its clever retention system and integrated protection for the sight, your entire setup remains safely secured and ready for immediate use. This makes this holster particularly appealing to airsoft players, instructors, sport shooters and professionals who work with modern pistol setups.

Common mistakes
