ECM Precision x Landers Weapon Systems: Introducing the R11 Chainsaw Grip Module

Posted by ECMPrecision on Jun 5th 2026

If you've been following the custom pistol world, you already know that Landers Weapon Systems (LWS) has made a name for itself with some of the most aggressive and recognizable slide work in the game. Their Chainsaw serrations — no-compromise, unapologetically brutal — have become a signature look for serious shooters who want function and style in equal measure.

Now, that same iconic texture has found its way onto ECM Precision's aluminum grip platform. The result is the R11 Chainsaw P365 Grip Module, a first-of-its-kind collaboration between ECM Precision and Landers Weapon Systems, and one of the most exciting product launches we've been a part of.

Two Brands, One Vision

This collaboration is a natural fit. ECM Precision has built its reputation on precision-machined aluminum grip modules for the SIG Sauer P365 platform — grips that are tighter, stronger, and more ergonomically refined than anything you'll find in polymer. Landers Weapon Systems is known for pushing the limits of slide machining and texture design, with the Chainsaw pattern becoming a cult favorite in the shooter community.

When both teams got together, the goal was simple: take LWS's signature Chainsaw texture and apply it to ECM's proven R11 grip architecture. The outcome speaks for itself.

As one early customer put it: "The minute I saw those needle tips on the Chainsaw grip I knew I had to have it. Absolutely did not disappoint one bit... amazing, aggressive, perfect ergos, beautifully balanced."

The Weapons Collective agrees — they called it the MVP of EDC. You can check out their full video breakdown on YouTube.

What Makes the R11 Chainsaw Different

The R11 Chainsaw is built for shooters who demand aggressive traction, durability, and precision machining. It's not a grip for everyone — and that's the point. If you want passive grip textures and gentle handling, there are plenty of other options. If you want a grip that locks into your hand under recoil and doesn't let go, this is it.

Here's what's under the hood:

Material: Machined from solid 7075 aluminum — the same alloy used in aerospace and high-stress structural applications. This isn't a polymer frame with a texture overlay. Every feature of the Chainsaw grip is cut directly into billet aluminum, giving you a level of rigidity and durability that polymer simply can't match.

The Chainsaw Texture: The defining feature of this collaboration. The Chainsaw texture pattern is engineered to lock your hand in place the moment the gun recoils. It's aggressive — intentionally so. Shooters who have handled it describe it as the kind of grip that wants to hold on as much as you do.

Integrated Design: Unlike some grip modules that rely on removable grip panels, the R11 Chainsaw is one piece. There are no panels to lose, no screws to come loose under stress. The integrated design maximizes rigidity and gives the grip a clean, purposeful look.

Extended Beavertail: Improved recoil management starts at the top of the grip. The extended beavertail gets your hand higher on the gun, reducing muzzle flip and giving you a more natural shooting position.

Ergonomic Trigger Guard Undercut: A proper undercut allows a higher grip and reduces hand fatigue during extended range sessions. It's a small detail that makes a big difference once you've experienced it.

1913 Accessory Rail: Lights, lasers, whatever you run — the precision machined Picatinny rail handles it.

Platform Compatibility: The R11 Chainsaw is available for the SIG Sauer P365 Macro and Fuse platforms, and is compatible with P365 3.1, Macro, and Fuse slides and magazines.

Build It Your Way

One of the things that makes ECM Precision's grip modules stand out is the level of customization available. The R11 Chainsaw is no different. When you order, you can configure your build to match exactly how you carry and shoot:

Safety Option: No Safety or Manual Safety
Magwell Option: Standard or Carry Magwell (+$50)
Base Pad Option: Carry 17 Round Base Pad (+$39.99), or Competition 17 Round Base Pad (+$59.95)

Whether you're building a carry gun, a range pistol, or a competition setup, the R11 Chainsaw can be spec'd to fit.

Pair It With a Ramm Tactical Trigger

If you really want to take your P365 build to the next level, consider pairing the R11 Chainsaw with a Ramm Tactical Sig P365 Leverage Trigger Kit. Ramm Tactical has become a go-to for P365 shooters looking for a better trigger pull — reduced pre-travel, a cleaner break, and a more consistent reset. Their leverage trigger system is a well-known complement to ECM's aluminum grip modules, and the combination results in a pistol that is genuinely fun to shoot fast and accurately.

If you want a turn-key custom P365 build, Ramm Tactical even offers complete custom pistols built on ECM Precision grip modules with their triggers already installed.

The Bottom Line

The R11 Chainsaw is more than a grip module — it's a statement about what two passionate, precision-focused companies can build when they work together. LWS brought the texture. ECM brought the platform. The result is a grip that looks as aggressive as it performs.

If you're serious about your P365 build and you want a grip that keeps up with you at the range or on the street, the R11 Chainsaw deserves a serious look.
