Taran Tactical Innovations Firepower Base Pad Kit SW MP 9mm 40SW 2 4 Magazine Extension Flat Black MPB940 000 UPC 810003108173
Product Description
The Taran Tactical Innovations® Firepower Base Pad Kit for Smith & Wesson® M&P 9/40 (SKU: MPB940-000 / UPC: 810003108173) is an American-made, competition-proven magazine extension designed to increase onboard round count and accelerate reload efficiency. Built specifically for full-size factory M&P steel magazine bodies, this precision extension increases overall capacity by +4 rounds in 9x19mm (delivering 21+1 total rounds) and +2 rounds in .40 S&W (delivering 17+1 total rounds). Delivering maximum reliability without the need for an aftermarket spring swap, the +2/4 Firepower pad provides a streamlined, balanced profile tailored for duty carry, home defense, and USPSA competition.
Each base pad is precision CNC-machined in the United States from solid billet aerospace-grade 6061-T6 aluminum, eliminating the structural flex, cracked feed interfaces, and floorplate separations common to polymer aftermarket extensions. The exterior is treated with a rugged MIL-A-8625 Type III Class 2 Hardcoat Anodize in Flat Black, providing superior resistance against environmental corrosion, aggressive cleaning chemicals, and high-velocity ground impacts on gravel or concrete. Weighing approximately 1.1 ounces, the added mass provides essential gravity assistance, ensuring empty magazines eject completely clear and drop free during rapid slide-lock reloads.
The unit features TTI's patented push-pin locking detent, providing a completely tool-free field stripping experience without requiring loose floorplates, separate clamp bars, or fragile set screws. Designed to work directly with the factory OEM magazine spring, installation is fast and hassle-free. Conforming strictly to the USPSA 140mm (141.25mm) maximum gauge rule, this extension is fully sanctioned for USPSA competition divisions, making it the choice upgrade of national champion shooters Julie Golob and Team Miculek.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Smith & Wesson full-size OEM M&P 9mm (17-round) and M&P .40 S&W (15-round) factory magazine tubes (both 1.0 and M2.0). CRITICAL fitment warnings: Will NOT work on ANY M&P Metal Series pistols. Will NOT work on M&P Competitor Series pistols due to factory magwell funnel clearance limits. Does NOT fit compact flush-fit magazine tubes, M&P Shield, Shield Plus, Shield EZ, M&P 10mm, or M&P .45 ACP models. Do NOT use with aftermarket ProMag or ETS magazines. Do NOT adjust or torque the rear pin set screw; it is factory threadlocked with Loctite® to precise tension and forcing it will strip the head. The factory lower floorplate insert MUST be removed before assembly.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty. Wear ballistic eye protection during magazine maintenance.
- Depress the factory floorplate insert locking button using an armorer punch, slide the OEM plastic floorplate forward off the magazine rails, and carefully capture and relieve spring tension.
- Extract the OEM spring assembly and remove the factory plastic or metal bottom floorplate insert completely; the TTI base pad is engineered to seat directly against the bottom coil of the stock spring without the insert.
- Reinsert the factory spring and follower into the steel magazine body, compress the lower coils upward into the tube, depress the rear push-pin downward, and slide the TTI base pad fully onto the magazine rails until seated.
- Push the stainless steel push-pin upward until it firmly locks behind the rear magazine rail notch; hand-load to verify full +4 (9mm) or +2 (.40 S&W) capacity, ensure positive follower movement, and conduct a dry-fire mag-drop check prior to range staging.
