Sig Sauer P320 XFULL LXG Laser-Engraved Grip Module - Full-Size Frame, Medium Girth, Advanced Polymer, Matte Black Finish - 8901393
Product Description
Upgrading your primary modular handgun platform to achieve maximum recoil management and handling security traditionally required permanent, costly custom gunsmith stippling. Standard factory polymer housings can feel slick in cold or humid conditions, causing the pistol to twist during high-speed defensive strings. The **Sig Sauer® P320 XFULL LXG Laser-Engraved Grip Module (8901393)** eliminates this tactical bottleneck. It leverages the P320's modular architecture to deliver an aggressive, laser-sculpted factory upgrade that swaps onto your handgun in seconds.
Proudly engineered and precision-cut at Sig Sauer's modern facility, this non-serialized **XSeries Full-Size (XFULL)** polymer frame shell features a custom **LXG laser-engraved stippling pattern**. This intricate cross-hatched layout delivers a multi-tiered texture matrix that locks tightly into your palm when compressed under tight firing leverage, yet remains smooth enough for snag-free concealment under cover garments. The **Medium size profile** is sculpted with an extended beaver-tail layout, a deeply undercut trigger guard for a higher grip axis, and a full-length 5-slot Picatinny rail to accommodate tactical weapon lights.
Equipped with a pre-installed factory magazine release catch assembly and designed to accept internal weight bars or magazine funnel adapters, this turn-key grip housing maximizes staging utility directly on your workbench.
*Armorer Bench Notes & Real-World Framing Guidance: The Sig Sauer 8901393 grip housing module arrives completed with the bare polymer XFULL frame chassis and a pre-assembled factory magazine catch mechanism. PROPRIETARY CO-DEPENDENT FCU INTERFACE MATRIX: This replacement frame sleeve is designed natively, strictly, and exclusively to host the **Sig Sauer P320 serialized Fire Control Unit (FCU)**. *Multi-Caliber Barrel Tracking Capability:* It is cross-compatible with P320 slide assemblies chambered in **9mm Luger, .40 S&W, and .357 SIG**. Caliber Fitment Restriction: It **is completely incompatible with .45 ACP or 10mm Auto FCUs and slide groups** due to differing internal block dimensions. *Slide Alignment Metrics:* This full-length dust cover is optimized for **4.7-inch Full-Size slides or 5.0-inch variants (like the M17 or XFive)**. If paired with a shorter 3.9-inch Carry/Compact slide, the frame spring dust cover will extend past the muzzle tip. Armorer Workbench Staging Sequence: 1. Visually and physically confirm your host firearm is completely unloaded, the magazine is removed, and the chamber is safe. 2. Lock the slide back, rotate the disassembly lever downward 90 degrees clockwise, and pull the slide assembly forward off the frame rails. 3. Rotate the disassembly pin counter-clockwise while pulling it out completely from the left frame wall. 4. Lift the serialized stainless steel FCU chassis upward and forward out of its seat within the factory grip housing. 5. Drop the FCU assembly down into the rear pocket of the new 8901393 module first, pressing flat until the trigger safety loops snap into alignment. 6. Reinsert the disassembly lever pin and remount your top slide assembly downrange, conducting full manual action dry-fire checks on your bench before field deployment.*
