Description
Smith & Wesson SD and SDVE owners know the frustration of running dry in the middle of a stage or during a critical reload. This Extended Capacity Base Pad delivers the extra rounds you need without compromising the slim profile your holster rig demands. Machined from high-strength polymer, it adds three (3) rounds to standard 9mm magazines and two (2) rounds to .40 S&W magazines—giving you more time on target and fewer magazine changes.
Designed for the serious shooter who relies on their duty gear or competition setup, this base pad fits the following magazines:
- Smith & Wesson SD and SDVE (9mm and .40 S&W)
- Sigma series pistols (Sigma “C”, “F”, and “VE”)
- SWVE models
- SD 2.0 Series 16-round magazines
Installation is straightforward—no permanent modification required. The base pad snaps securely onto your existing magazine floor plate, and the dimpled bottom surface provides quick tactile identification when you’re grabbing a reload under pressure. You’ll feel the difference when your hand hits that textured surface in the dark or during a high-speed reload.
Real-world benefits for your training and competition:
- Increase 9mm magazine capacity by three (3) rounds—no more short-counting on the clock
- Add two (2) rounds to .40 S&W magazines for extended strings of fire
- Durable polymer construction resists impact and wear from repeated use
- Low-profile design fits standard duty holsters and competition pouches
- Easy to swap between magazines for range days or match prep
This is a direct upgrade for shooters who refuse to compromise on capacity. Whether you’re running a stage, stacking drills, or carrying a backup magazine on your belt, the extra rounds mean less time reloading and more time focusing on fundamentals. The base pad integrates seamlessly with your existing gear—no adapter plates or special tools needed.
Important fitment note: This base pad is caliber-specific. Select the correct option for your 9mm or .40 S&W magazine. It is compatible with factory standard-capacity magazines only. Not for use with aftermarket extended tubes or modified springs. Installation requires no gunsmithing—simply remove your factory floor plate and replace with this unit.
