Description
Carry more rounds without changing your grip or holster fit. The Extended Capacity Base Pad for the SDVE adds three rounds to your standard 9mm magazine and two rounds to your .40 S&W magazine. That means you go from 16 to 19 rounds in 9mm, or from 14 to 16 in .40, giving you that extra margin when seconds count. Designed specifically for Smith & Wesson SD and SDVE model pistols, this base pad also fits Sigma series magazines, including the Sigma “C”, “F”, “VE”, and SWVE. It even works with SD 2.0 Series 16-round magazines, so if you have one of those, you get the same capacity boost.
Installation is straightforward. The base pad slides onto the magazine floor plate and locks in place with the existing spring and follower. No tools, no gunsmithing, no lost time at the range. The bottom surface is dimpled for quick tactile identification, so when you reach for a reload in low light or under stress, you know instantly which magazine has the extra rounds. That dimple saves you from fumbling or guessing.
Key benefits for your carry or competition setup:
- Adds 3 rounds to 9mm SD, SDVE, Sigma, SWVE, and SD 2.0 16-round magazines
- Adds 2 rounds to .40 S&W SD, SDVE, Sigma, SWVE, and SD 2.0 magazines
- Dimpled base for easy identification by feel — no need to look
- Simple, tool-free installation — works with factory springs and followers
- Maintains standard magazine length — no holster or grip changes required
- Caliber-specific design ensures reliable feeding and function
Specs and fitment: This base pad is caliber-specific. For 9mm magazines, you get +3 capacity. For .40 S&W magazines, you get +2 capacity.
