The Under Cover Holster for the ECM R11 Fuse

When it comes to everyday concealed carry, comfort and concealability matter just as much as retention and reliability. The Under Cover Holster for the ECM R11 Fuse / Fuse Slide is purpose-built to deliver all four—without unnecessary bulk or gimmicks. Designed specifically for ECM Precision firearms, this inside-the-waistband (IWB) holster offers a clean, low-profile solution for responsible daily carry.

Made in the USA by veterans and constructed from durable Kydex, the Under Cover Holster is designed for users who want a secure, discreet, and comfortable carry option that integrates seamlessly into everyday life.

Our team at ECM Precision is going to break it down.

Purpose-Built for ECM R11 Fuse Pistols

Unlike generic holsters that rely on “close enough” fitment, this holster is engineered specifically for the ECM R11 Fuse / Fuse Slide platform. That dedicated design results in a snug, consistent fit that improves retention, protects the trigger guard, and ensures smooth, intuitive draws for your everyday carry gun.

Because it’s not designed to accommodate tactical lights, the holster maintains a slimmer overall profile—an important factor for deep concealment and long-term comfort when carrying IWB.

Comfort and Concealability for Everyday Carry

The Under Cover Holster is optimized for inside-the-waistband carry, making it an excellent choice for daily concealed carry. Its slim Kydex construction hugs the body closely, reducing printing and hot spots, even during extended wear.

Whether you’re seated, standing, or moving throughout the day, the holster’s low-profile design keeps your firearm secure without shifting or digging into your side.

Key Comfort Benefits:

• Slim IWB profile for maximum concealment

• Body-hugging design to reduce printing

• Lightweight Kydex that won’t absorb moisture

Adjustable Retention for a Personalized Fit

Retention is a critical factor in any concealed carry holster, and this holster delivers with adjustable retention screws. This allows users to fine-tune the draw resistance to match their preference—tight enough for secure carry, yet smooth enough for fast, consistent access when needed.

This level of adjustability makes the holster suitable for both experienced carriers and those newer to IWB concealed carry.

Integrated Sweat Guard for Added Protection

Daily carry often means exposure to sweat and moisture, especially during warmer months or extended wear. The built-in sweat guard helps protect both the firearm and the wearer by creating a barrier between the gun and the body.

This feature not only enhances comfort but also helps preserve the finish and function of your ECM R11 Fuse over time.

Veteran-Made Quality You Can Trust

One standout feature of the Under Cover Holster is its veteran-made craftsmanship. Proudly made in the USA, this holster reflects attention to detail, durability, and real-world usability—qualities that matter when choosing a concealed carry setup you depend on daily.
