Description
Sig's P365 X-Macro is already a solid platform, but the factory polymer grip leaves some room for improvement, especially if you've got bigger hands or want more mass to soak up recoil. The Sharps Bros Gen3 grip module addresses that by replacing the stock housing with a machined block of 7075-T6 aluminum, finished in a durable Mil-Spec black anodizing and paired with matching black aluminum grip panels. The result is a grip that feels more like a purpose-built handgun frame than a plastic shell.
Gen 3 Ergonomics on the P365 X-Macro Grip Module
This version isn't just a cosmetic reskin of earlier Sharps Bros modules. The Gen3 brings noticeably more aggressive panel texturing, a redesigned steel lug system for a tighter overall fit to the fire control unit, and built-in provisions for adding a mag funnel down the road. The trigger guard has also been reshaped with an undercut and finger grooves so your support hand can get higher and tighter to the bore axis, which helps with both comfort and follow-up shots.
Grip Width and Control on the Gen3 Module
At 1.3 inches wide compared to the factory 1.1-inch module, this grip fills the hand more naturally without turning the X-Macro into something bulky or hard to conceal. The ambidextrous gas pedals on both sides of the frame, licensed from GoGun USA, give you a natural thumb ledge and indexing point no matter which hand you shoot with, and they make a real difference in managing muzzle flip. Every edge on the module is cleanly radiused too, so there's nothing digging into your hand during a long range session or a full day of carry.
Installation is a direct swap for the OEM grip module, though a couple of things are worth knowing ahead of time. The stock magazine release assembly is not included, so you'll need to transfer yours over or pick up a replacement. Because of the integrated thumb ledges, most off-the-shelf Kydex holsters will need minor reforming to fit properly, so it's worth checking holster compatibility before you commit to a daily carry setup.

Frequently Asked Questions
Will the Gen3 grip module fit my Sig P365 X-Macro?
Yes, this module is built specifically for the Sig P365 X-Macro fire control unit and also fits P365 XL slides. It's a direct replacement for the factory polymer grip module, so no fitting or gunsmithing is required to get it on your pistol.
Does this grip module come with a magazine release?
No, the magazine release assembly is not included. You'll need to transfer your existing stock mag release over to the new module, or pick up a replacement if yours is worn.
Will my current holster still work with this grip module?
Most standard Kydex holsters will need some minor heat reforming to accommodate the integrated thumb ledges on the Gen3 design. If you want a guaranteed fit, look for holsters made specifically for the Sharps Bros grip module rather than a generic X-Macro holster.
What's different about the Gen 3 version compared to earlier Sharps Bros grip modules?
The Gen3 brings more aggressive grip panel texturing, a redesigned steel lug system for a tighter fit to the fire control unit, and built-in provisions for adding a mag funnel later on. The trigger guard undercut and finger groove geometry have also been refined for a more natural, higher grip.
