Springfield Armory | XD(M) Magazine | 40 S&W | Stainless

Springfield's factory XD(M) magazine uses a stainless steel, double‑column body with a steel spring and polymer follower and baseplate, built to the exact tolerances of the XD(M)'s frame and caliber. Capacities are matched specifically to caliber and frame size -⁠- 16 rounds for .40 S&W full‑size, 19 for 9mm, and more in extended configurations -⁠- so you're getting the correct fit rather than a magazine stretched across multiple calibers. The genuine factory‑spec magazine engineered alongside the pistol itself.
