Sig Sauer P365 FUSE Laser Engraved XMacro Grip Module Black 8901773 UPC 798681710799
Product Description
The Sig Sauer® P365-FUSE / P365-XMACRO Laser-Engraved Grip Module (SKU: 8901773 / UPC: 798681710799) represents the factory-engineered pinnacle of full-capacity ergonomics for the modular P365 platform. Originally engineered for the duty-length P365-FUSE, this OEM frame allows shooters to convert standard micro-compact P365, P365X, or P365XL builds into full-grip, competition- and tactical-ready setups capable of seating 17-round and 21-round factory magazines flush without sacrificing sub-compact concealability.
Constructed from high-tensile, impact-modified glass-reinforced polymer, the P365-FUSE module is impervious to extreme thermal expansion, bore solvents, sweat acidity, and high-impact duty abuse. Unlike smooth standard polymer frames or aftermarket hand stippling jobs that degrade structural integrity, this module features deep, laser-engraved multi-directional hexagonal micro-texturing across the front strap, side grip panels, and interchangeable backstrap. This abrasive matrix provides non-slip control under rapid-fire recoil and wet-weather operations without shredding concealed carry garments or abrasive wear against bare skin.
Engineered with tactical integration at the forefront, this grip module features a true Mil-Std 1913 Picatinny rail along the dust cover, eliminating the need for proprietary adapter clamps when mounting modern tactical weapon-mounted lights and laser systems. Combined with the included bolt-on flared competition magazine well, reload times are dramatically slashed under stress, guiding double-stack steel bodies effortlessly into the magazine channel during tactical reloads or high-speed competition stages.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct drop-in fit for standard, non-manual safety Sig Sauer P365 9mm Luger Fire Control Units (FCUs). Compatible with P365-XL, P365-XMACRO, and P365-FUSE slide lengths. [CRITICAL NOTICE: Does NOT fit California-compliant P365 FCU models due to the magazine disconnect safety mechanism. Does NOT accommodate factory manual safety levers unless manual safety cuts are machined into the polymer. Will NOT seat standard 10-round or 12-round flush-fit P365 magazines; requires native 17-round or 21-round XMACRO magazines. Dust cover extends to full XL/XMacro slide length; 3.1" slides require a compensator to clear the front rail.]
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty.
- Lock the slide to the rear, rotate the takedown lever clockwise past 90 degrees, release the slide catch, and carefully remove the slide assembly forward off the frame.
- Using a non-marring 1/8" punch, drive the rear receiver pin outward from either side of the existing grip frame and lift the modular Fire Control Unit (FCU) upward and forward out of the chassis.
- Seat the forward chassis tabs of your FCU into the interior indexing recesses of the new 8901773 FUSE module, pivot the rear housing downward into alignment, and reinsert the rear receiver retention pin until fully centered.
- Install the desired interchangeable backstrap, remount your slide assembly, perform a comprehensive armorer dry-fire function test (trigger reset, disconnector check, and slide lock verification), and confirm smooth magazine insertion and ejection prior to live-fire staging.
