SIG SAUER P365XL Standard Gray Grip Assembly

The SIG SAUER P365XL grip assembly is the factory replacement grip module that lets you upgrade your standard P365 to the larger XL frame size. If you've got a P365 and want more real estate in your hand without buying a whole new gun, this gray grip assembly is the straightforward solution. It's a genuine SIG factory part, which means it's engineered to spec and built to the same standard as the gun itself.

This grip module works with P365 handguns that do not have a manual safety. The XL frame gives you a longer sight radius and a bit more grip surface—genuinely useful upgrades for shooters who want better control and a faster sight picture without changing caliber or overall gun platform. It's the kind of upgrade that makes sense for competition shooters, folks who train regularly, or anyone who simply prefers a larger platform but likes everything else about the P365 ecosystem.

Installation is straightforward—this is a genuine OEM part, not an aftermarket interpretation. The standard gray finish matches SIG's factory aesthetic, so your gun will look factory-correct once you're done. Whether you're swapping it out as a replacement or doing your first frame upgrade, you're getting the part SIG designed for this job.
