Popular Sig Sauer P365 Grip Modules
The Sig P365 is known for its modularity, allowing shooters to swap grip modules to improve handling, ergonomics, and overall performance. Whether you’re looking for a simple factory replacement or a premium aluminum upgrade, several grip modules are available to fit different needs. Below, we break down some of the most popular options.
Sig Sauer P365 Grip – The Standard Factory Module
The factory Sig Sauer P365 grip module comes with the pistol and is the baseline for all upgrades. It features a compact design for concealed carry, a lightweight polymer frame, and a comfortable, stippled grip. While it offers solid ergonomics, many shooters upgrade for improved control, better texture, or a different frame size.
Sig Sauer P365 X Macro Grip Module – A Versatile Upgrade
The Sig Sauer P365 X Macro grip module is a popular upgrade that enhances the standard P365 by offering a slightly longer frame with an integrated Picatinny rail. This allows for better accessory compatibility, such as weapon lights and lasers, while improving grip and recoil management. Designed to accommodate higher-capacity magazines, it’s an excellent choice for those who want more firepower without significantly increasing the overall size.
Sig Sauer P365 AXG Legion Grip Module – Premium Feel and Performance
The Sig P365 AXG Legion grip module is an excellent choice for shooters looking for a high-end, aluminum-framed grip module. Made from precision-machined aluminum, it provides added weight for improved balance and recoil mitigation. The Legion version includes aggressive texturing and ergonomic enhancements, making it ideal for those prioritizing a premium feel and superior performance.
Sig Sauer P365 AXG Grip Module – Comparing AXG vs. AXG Legion
The Sig Sauer P365 AXG grip module offers the same aluminum construction as the Legion variant but without some Legion-specific enhancements. While both provide a robust and durable grip, the standard AXG module is slightly less aggressive in texture. It is a good option for those who want the benefits of an aluminum frame without the Legion branding or additional grip modifications.
Aftermarket Grip Modules – Custom Options for Maximum Personalization
Beyond factory offerings, several aftermarket manufacturers provide Sig P365 grip modules with unique features. Wilson Combat, for example, produces custom grip modules with enhanced stippling, recontoured frames, and improved ergonomics. These grips allow shooters to fine-tune their P365’s feel to match their specific preferences, whether for everyday carry, competition shooting, or home defense.
With various grip modules available, choosing the right one depends on personal preference, intended use, and desired features. Next, we’ll explore key factors to consider when selecting a Sig P365 grip module for your needs.

Factors to Consider When Choosing a Grip Module
Selecting the right Sig Sauer P365 grip module depends on several factors, including ergonomics, material, customization options, and intended use. Whether you’re upgrading for better control, enhanced durability, or a personalized feel, understanding these key aspects will help you make the best choice.
1. Ergonomics and Comfort
One of the most important factors when choosing a grip module is how it feels in your hand. Some grip modules, like the Sig Sauer P365 X Macro grip module, offer a slightly larger frame for improved handling, while others, like the factory Sig P365 grip, are designed for maximum concealability. Consider grip texture, palm swell, and finger placement to ensure a comfortable and secure hold.
2. Material and Durability
Grip modules come in different materials, each with its advantages:
- Polymer Grip Modules – Lightweight and durable, ideal for everyday carry.
- Aluminum Grip Modules – Found in models like the Sig P365 AXG Legion grip module, aluminum frames add weight for better balance and recoil management.
Polymer grip modules are an excellent choice for those prioritizing weight savings, while aluminum grips offer a premium feel and increased durability.
3. Customization and Accessory Compatibility
If you plan to customize your P365, consider grip modules with integrated accessory rails. For example, the Sig Sauer P365 X Macro grip module includes a built-in Picatinny rail, allowing you to attach lights, lasers, or other accessories. Some aftermarket options offer custom stippling and grip enhancements for a more personalized touch.
4. Concealability vs. Control
A compact grip module like the standard Sig Sauer P365 grip is more straightforward to conceal, making it an excellent choice for everyday carry. However, larger modules like the Sig Sauer P365 X Macro grip module provide more surface area for a firmer grip, which can improve accuracy and recoil control. Finding the right balance between concealability and control depends on your specific needs.
5. Compatibility with Magazines and Fire Control Unit
Not all grip modules are compatible with every Sig Sauer P365 variant. Some modules, like the Sig Sauer P365 AXG grip module, require specific magazines due to their different frame size. Before purchasing, ensure your chosen grip module is compatible with your existing setup, including your fire control unit and preferred magazine capacity.
By evaluating these factors, you can choose the best Sig Sauer P365 grip module to match your shooting style and intended use. Next, we’ll walk through the installation process to help you easily swap out your grip module.
