Improve R11 Grip Texture, Balance, and Feel With a Solid 360 Brass Grip Insert

When it comes to customizing and upgrading an R11 grip module, small changes can make a noticeable difference in how the firearm feels in your hand. The 360 Brass Cheese Grater Palm Swell Grip Insert from ECM Precision combines aggressive grip texture, ergonomic design, and added weight in one upgrade for your Sig Sauer.

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

What Is the 360 Brass Cheese Grater Grip Insert?

The 360 Brass Cheese Grater Palm Swell Grip Insert is designed specifically for ECM Precision R11 grip modules, which are an upgrade for the Sig Sauer P365. It is machined from solid 360 brass and adds approximately 3.7 ounces to the rear of the R11. This additional weight changes the balance and overall feel of the grip while providing a more substantial platform in the hand.

The insert also features ECM Precision's signature cheese grater texture, giving shooters an aggressive, tactile grip surface. This can help improve the draw from the holster, which can be beneficial not only during range and competition use, but also during defensive situations.

Aggressive Grip Texture for Better Traction

Grip texture is an important part of how a firearm feels during shooting. A more aggressive texture can provide additional traction and help minimize unwanted movement between the hand and grip, reducing recoil, meaning you can have better accuracy and tighter shot groupings. 

The cheese grater pattern is designed to provide a secure, tactile feel without being excessively uncomfortable, performance without compromise. ECM Precision describes its rough-textured inserts as an option for shooters looking for increased stability and grip control.

Palm Swell Design for a Comfortable Grip

The Palm Swell design adds another layer of ergonomics to the insert. Instead of simply increasing texture, the profile is designed to provide a more natural feel in the palm.

This combination of palm swell geometry and aggressive texture gives the R11 a distinctive feel that can appeal to shooters who want more feedback from their grip.

Added Brass Weight

One of the biggest differences between the 360 Brass Cheese Grater and standard grip inserts is its construction.

The solid 360 brass insert adds approximately 3.7 ounces to the backend of the R11, shifting additional weight toward the rear of the grip.

For shooters who prefer a heavier, more substantial grip, this can be an appealing way to change the balance and feel of an R11 without replacing the entire grip module.

Is a Cheese Grater Grip Insert Right for You?

The best grip texture ultimately comes down to personal preference and what makes the shooter feel confident. More aggressive textures can provide additional traction, while smoother or more moderate textures may be more comfortable during extended use.

The 360 Brass Cheese Grater Palm Swell Grip Insert is a strong option for R11 owners who want:

• Aggressive grip texture
• Added weight
• A more substantial grip feel
• An ergonomic Palm Swell profile
• A distinctive brass appearance
• Additional R11 customization

ECM Precision also offers several other R11 grip inserts, including standard Palm Swell, HEX, Grenade Pattern, and other designs.
