Smith Defense S365 Brings Modular Design to the P365

Smith Defense has stepped into the spotlight with a strong debut—launching its very first product, the S365, a rugged, all-metal grip module engineered for the SIG Sauer P365 lineup. Precision-machined from solid billet aluminum, this grip module isn’t just an aesthetic upgrade—it’s a serious performance enhancer for concealed carry enthusiasts, everyday carriers, and those who simply want more out of their micro-compact.

Whether you’re running a standard P365 or rocking the extended 365L slide, the S365 is built to adapt. Two included dust covers allow quick configuration changes, while the integrated 1913 Picatinny rail ensures full compatibility with lights, lasers, and other rail-mounted accessories. No proprietary headaches here—just straightforward modularity.

Why the S365 Stands Out

There’s something to be said about the feel of a metal grip in the hand. The S365 adds roughly 4 ounces of solid billet weight to your build—enough to help reduce felt recoil without tipping the scale toward overbuilt. That extra mass contributes to smoother tracking, improved shot-to-shot recovery, and a more planted feel that’s often missing from polymer frames.

The grip module is also fully customizable. With removable grip panels, shooters can swap textures or materials to fine-tune the fit to their preferences—whether you’re after aggressive control or sleek minimalism. This kind of ergonomic versatility isn’t just about comfort; it translates directly into tighter groups and better performance under pressure.

Drop-In Simplicity, No Guesswork.

The S365 is a true drop-in upgrade. Just move your FCU into the module, and you’re good to go. No fitting, no shimming, no frustration. Everything is precisely engineered to work with the entire P365 family, including the standard, X, XL, and long-slide variants. Even manual safety cutouts are pre-machined, making this a plug-and-play option for any user.

Durability That Matches Its Looks

CNC-machined from a solid block of aluminum, the S365 grip frame is built to last. You’re not dealing with cast or injection-molded parts here—this is a premium, monolithic design that brings real structural integrity to your P365 setup. It’s the kind of foundation you can build around with confidence, knowing it’s ready for daily carry or rigorous use on the range.
