Description
Sig's P365 X/XL is a fantastic little pistol, but that stock polymer grip frame always felt like it was built for the lowest common denominator. Sharps Bros set out to fix that with this Gen 3 module, a billet 7075-T6 aluminum frame that swaps the plastic feel for something with actual heft and personality. The Brazilian cherry wood panels give it a classic, custom look that stands out from the sea of black polymer guns at the range, and the Mil-Spec black anodized finish on the frame itself means it can still take a beating during regular carry.
What sets this Gen 3 version apart from earlier Sharps Bros modules is the refinement work that went into the ergonomics. The grip panel texturing is more aggressive for a better hold under stress or sweaty hands, the steel lug system was redesigned for a tighter, more consistent fit with your fire control unit, and there's now provision for adding a mag funnel if you want to speed up reloads. The frame widens the grip from the factory 1.1 inches to 1.3 inches, which sounds small on paper but translates to a noticeably fuller, more confident hold, especially if you've got average to larger hands and always felt like the P365 was a bit too skinny.
Thumb Ledges Built Into the Frame
Both sides of this Sharps Bros grip module feature integrated thumb ledges, a patented design that gives you a natural indexing point no matter which hand is running the gun. It's a small detail that makes a real difference in recoil management, especially on a compact 9mm that can feel snappy in a smaller frame. Combined with the added weight of the aluminum body over the factory polymer, felt recoil is noticeably tamer and follow-up shots come faster.
Fit and Installation Notes for the Gen 3 P365 X/XL Module
This module accepts any P365 slide, including the standard P365, P365X, P365XL, and P365 X-Macro, so it's a flexible upgrade if you're planning a build rather than a straight swap. Keep in mind this version is not compatible with the manual safety FCU, and the magazine release assembly isn't included, so you'll need to transfer your factory parts over or pick up a replacement. Because of the built-in thumb ledges, most Kydex holsters molded for the factory grip will need a little heat reforming to fit properly, though holsters designed specifically for this module are available if you'd rather skip that step.

Frequently Asked Questions
Will the Sharps Bros Gen 3 P365 X/XL grip module work with my manual safety Sig?
No, this particular version is not compatible with the manual safety fire control unit. Sharps Bros does make a separate manual safety cut version of the Gen 3 module if that's what your P365 is running, so double check your FCU type before ordering.
Does this grip module come with a magazine release?
No, the magazine release assembly is not included with this module. You'll need to transfer your factory mag release over during installation, or pick up a new Sig OEM mag release assembly if yours is worn.
Will my current holster still fit after I install this grip module?
Most Kydex holsters molded for the factory P365 X/XL grip will need some minor heat reforming to accommodate the integrated thumb ledges on this module. If you'd rather skip that hassle, there are holsters built specifically to fit the Sharps Bros contours.
Is this a straightforward swap for someone who isn't a gunsmith?
Plenty of owners install these themselves at home, but the tolerances are tight since this frame is machined to a higher standard than the factory polymer housing. If you're not confident pulling apart your fire control unit, having a gunsmith handle the swap is a smart call, and it's worth using a drop of Loctite on the set screws once everything is seated.
