Optics Ready Slide for Modern Performance

The Springfield XD MOD.4 OSP is equipped with a factory optics-ready slide, allowing shooters to quickly and securely mount a wide variety of micro red dot sights. Whether you choose a Trijicon RMR, Holosun 507K, Sig Romeo, or another compatible optic, the OSP cut provides a stable mounting platform without requiring custom slide work. This feature dramatically improves target acquisition speed and accuracy, giving shooters a significant advantage in both competition and defensive scenarios. The optics-ready design makes this pistol highly adaptable for today’s shooter.

4-Inch Barrel for Superior Accuracy

Featuring a 4-inch hammer-forged barrel, the XD MOD.4 OSP offers an excellent balance between concealability and ballistic performance. The longer barrel provides increased muzzle velocity and a longer sight radius compared to shorter-barreled models, resulting in improved accuracy and better terminal performance. The hammer-forged construction ensures exceptional durability and consistent accuracy over thousands of rounds, making this pistol well-suited for both range use and defensive applications.

High-Visibility Fiber Optic Front Sight

This model is equipped with a bright fiber optic front sight and a white dot rear sight. The fiber optic front sight gathers ambient light to create a highly visible aiming point that is easy to acquire quickly in a variety of lighting conditions. This sighting system provides a clear advantage for fast and accurate shot placement during competition, training, or defensive situations where rapid target engagement is essential.

16-Round Magazine Capacity

The Springfield XD MOD.4 OSP comes with a 16-round magazine, offering significantly more capacity than many competing compact 9mm pistols. This higher capacity allows for extended shooting sessions with fewer reloads and provides a tactical advantage in defensive scenarios. The 16-round magazine is designed for reliable feeding and smooth operation, making this pistol an excellent choice for shooters who want maximum firepower in a full-size grip configuration.
