Brouwer LLC OEM SIG Sauer P320 Magazine Release Assembly - Pre-Configured for Right-Hand Dominant Shooters, Factory Steel Component Core, Drop-In Grip Module Interface, Matte Black Finish
Product Description
Overhauling a high-mileage defensive carbine module, assembling a new modular chassis framework, or replacing lost internal grip components requires small parts built to exact factory prints. Opting for sub-spec aftermarket pins can result in magazine catch drag, loose rattle tolerances, or a stiff thumb button that refuses to drop magazines cleanly under high-speed presentation stresses on your bench. The **Brouwer LLC® OEM SIG Sauer P320 Right Hand Magazine Release Pack** completely flatlines these manual cycling failures, delivering a **turn-key, factory-original single-side release cluster** pre-configured straight from official blueprints.
Proudly distributed and workshop-staged by the custom tuning team at Brouwer LLC, this internal component set features genuine factory original components built to withstand professional duty schedules. The assembly is centered around a solid **steel magazine catch body** treated with an anti-friction matte black finish to withstand harsh daily use. The kit includes the structural spring wire loop and the specialized chevron-textured plastic wedge block that captures the assembly securely inside the frame walls. Pre-configured natively for a right-hand layout—which positions the push button prominently on the left flank of the frame—this drop-in small parts kit simplifies weapon staging updates directly from your workbench.
Engineered to slide cleanly into the magazine release pockets of standard factory SIG frames, Brouwer M1811 polymer housings, and M1823 aluminum modular chassis systems, this factory-calibrated small parts group guarantees instant mechanical drop synchronization straight from your workspace bench.
*Armorer Bench Notes & Real-World Grip Assembly Staging Guidance: The Brouwer P320 OEM magazine release kit arrives workspace ready, containing 1x steel magazine catch bar, 1x internal coil retention spring, and 1x polymer retention wedge stop piece. UNIVERSAL SIG P320 GRIP MODULE INTERFACE MATRIX: The frame capture tracks are engineered natively, strictly, and dimensionally to drop into **any standard modular SIG factory grip module, Brouwer M1811 series polymer frame, or Brouwer M1823 billet aluminum chassis wrapper**. *Right-Hand Configuration Mapping Checklist:* Setting up this hardware loop in a **Right Hand orientation** explicitly positions the textured thumb pad on the **left side of the grip shell**, allowing right-handed operators to naturally depress the lock using their dominant thumb on the bench. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host SIG P320 long gun or pistol chassis is completely clear of live ammunition, the magazine is removed, and the fire control chamber is verified empty and safe. 2. Strip the steel slide assembly away from the receiver body and extract your central metallic Fire Control Unit (FCU) core frame to clear a direct path inside the plastic grip shell. 3. Insert the small coil spring straight into the central bore tunnel of the steel magazine catch body bar before attempting installation. 4. Guide the combined spring and steel catch bar into the horizontal frame channel from the right flank of the grip module, pushing it completely across until the left button head clears the surface. 5. While holding the catch bar firmly compressed against the frame using a non-marring bench tool, slide the small polymer wedge retainer clip down through the inner vertical alignment track inside the magwell walls. 6. Push the wedge down firmly until it snaps aggressively into the lock slot on the catch rod, then rapidly click the release button several times and drop an empty steel magazine tube into the channel to verify smooth retention lockup and instantaneous drops before rolling downrange.*
