Sprgfld Xd Slide Assy 9mm 4" W/ Ct

The Springfield XD Slide Assembly 9mm 4" with Corrected Taper (W/ Ct) is a factory replacement and upgrade slide system designed for Springfield XD full-size handgun platforms. This OSP-configured slide assembly allows existing XD owners to add optical sight capability to their service or duty weapons without purchasing an entirely new pistol, significantly extending the life and modularity of current platforms.

The 4-inch barrel configuration in 9mm delivers a practical balance between velocity retention and compact handling. The slide is pre-machined to accept OSP (Optical Sight Pistol) optics mounting plates, accommodating modern red dot systems from major manufacturers. The corrected taper (Ct) designation indicates precision manufacturing to Springfield's updated tolerance specifications, ensuring consistent lockup and zero retention. Included cover plates protect the optic mounting surface during transport or when running iron sights. The assembly arrives complete with all necessary components for installation on compatible XD frames.

This assembly serves law enforcement agencies, military personnel, and civilian operators who have invested in the XD platform and seek modernization without platform migration. The 9mm chambering provides cost-effective training and qualification ammunition economics while the 4-inch slide length maintains handling characteristics familiar to existing users. Departments evaluating optics-ready upgrade paths for legacy duty weapons find this solution cost-effective compared to wholesale platform replacement, preserving shooter familiarity with controls and ergonomics.

Springfield's XD platform has maintained wide adoption across federal, state, and local law enforcement for over two decades. This OSP slide assembly represents the manufacturer's modernization pathway for existing XD owners seeking contemporary optical mounting without equipment obsolescence.
