For over a decade, Smith Defense has been at the forefront of the firearms industry, forging its reputation through dedication, exceptional OEM work, and an unyielding commitment to excellence. Now we are proud to continue our journey with a clear vision: to craft the highest quality precision-machined parts for firearms enthusiasts and professionals alike.

The S365, made from billet aluminum, strikes a balance between durability and sleek aesthetics. Designed to accommodate user preferences, its modularity enables users to easily switch their setup between P365, P365X, P365XL, or the unique P365L. Another standout feature is the module’s weight – at approximately 4 ounces, it will enhance the stability and recoil management of your P365

Customization is at the forefront of the S365’s design. It includes standard and long interchangeable grip attachments and dust covers with standard 1913 Picatinny rail, ready for various attachments such as lights and lasers, unlike the proprietary Sig rail. Adding custom grip panels is also an option, allowing for a grip that feels uniquely yours.

Compatibility-wise, the S365 integrates seamlessly with the Sig P365 FCU. Its design promises an uncomplicated, drop-in fit, making installation straightforward and easy peasy.

Milled from a solid block of billet aluminum using precision CNC machining, the S365 provides outstanding strength and rigidity. Ergonomically, the module is crafted to enhance grip and control, which leads to improved accuracy. This new module is a solid option for those looking to enhance their SIG Sauer P365 offering a balance of aesthetics, customization, and functional improvements.
