Shark Coast Tactical Custom X65 Sharktooth Grip Module Sig Sauer P365X Black ZCSTGM 200 066 0410 01 UPC 810105513226
Product Description
Transform your concealed carry foundation with the Shark Coast Tactical Custom X65 Sharktooth Billet Aluminum Grip Module for the SIG Sauer® P365X and P365 platforms (SKU: ZCSTGM / 200-066-0410-01 / UPC: 810105513226). Engineered as a premium, heavy-duty upgrade to standard factory polymer grip frames, the X65 Sharktooth delivers rigid mechanical stability, eliminated frame flex, and an aggressive, tactile purchase. Designed specifically around the P365X footprint, this module balances a full three-finger combat purchase with the low-profile concealment envelope demanded by everyday carry professionals.
Precision CNC-machined from a monolithic billet of 7075-T6 aircraft-grade aluminum, the X65 Sharktooth replaces factory polymer flex with structural rigidity that absorbs recoil impulse and drives the muzzle flat during rapid shot strings. The frame is treated with a resilient MIL-A-8625 Type III Class 2 hardcoat anodized finish in deep matte black, shielding the aluminum from sweat, chemical solvents, abrasion, and harsh climate conditions. Machined directly into the side flanks and front strap is Shark Coast Tactical’s custom hybrid “Sharktooth” stippling pattern, which provides micro-abrasive mechanical traction that bites into skin tissues without tearing up undershirts or cover garments.
Operational ergonomics are enhanced with an extended high-sweep beavertail to eliminate slide bite, paired with an aggressive double-undercut trigger guard that allows the shooter’s support and firing hands to choke up directly beneath the bore axis. Up front, Shark Coast Tactical replaced the proprietary SIG tapered rail with a true modified 1913 Picatinny rail section, opening up a wider array of weapon-mounted lights and laser attachments. A subtly beveled internal magwell funnel accelerates dynamic speed reloads under tactical stress while seating flush-fit 12-round P365X/XL and extended factory magazines.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Direct drop-in fitment for non-manual safety SIG Sauer P365, P365X, and P365XL Fire Control Units (FCUs) utilizing 9mm Luger or .380 ACP slide configurations. CRITICAL WARNING: This module features a non-manual safety profile; FCUs equipped with an ambidextrous manual safety lever require modification or manual safety delete before installation. Due to the true 1913 Picatinny accessory rail profile and billet frame dimensions, standard factory polymer P365 holsters will NOT seat properly; pair exclusively with 1913-compatible or custom-molded aluminum module holsters.
- Ensure the host firearm is completely clear, drop the magazine, lock the slide rearward, and visually and physically inspect the chamber to verify the weapon is fully unloaded.
- Rotate the takedown lever clockwise to 6 o’clock, ease the slide assembly forward off the frame rails, and remove the barrel and recoil spring assembly.
- Using a non-marring 1/8-inch punch, drift out the rear receiver retention pin from the polymer grip module and set it aside.
- Gently lift the front of the Fire Control Unit (FCU) upward and pivot it out of the old polymer module, ensuring the sear spring and slide catch lever remain correctly seated.
- Angle the rear rails of the FCU into the Shark Coast Tactical X65 aluminum housing, press the forward receiver tabs flat until flush, reinsert the rear retention pin, remount your slide assembly, and perform a full function/reset check.
