-
Safety First: Always ensure the firearm is unloaded and clear of ammunition. Visually inspect the chamber and magazine well to confirm this.

Install the New Slide: Carefully install the new slide, ensuring proper alignment. Reinstall the recoil spring and guide rod assembly. Pay close attention to how the components fit together.
-
Reassemble the Pistol: Carefully reassemble the Walther PDP, following the field stripping process in reverse order. Make sure all parts are properly seated and aligned.
-
Function Check: Before using the pistol, perform a thorough function check. Cycle the slide several times to ensure smooth operation. Always verify the pistol is unloaded before performing this check.
-
Test Fire (at a safe range): Once you're satisfied with the function check, take the pistol to a safe shooting range to test fire it and verify functionality. Follow all safety regulations and local laws.
Troubleshooting Common Issues
- Slide won't fully seat: Double-check the alignment of all parts, particularly the recoil spring and guide rod assembly.
- Slide binds: The slide may be slightly out of alignment, or there might be debris interfering with its movement. Carefully inspect and clean all parts.
