How to Install P944 Wolff Gunsprings

The Ruger P944 is a centerfire, double-action pistol chambered for the .40 Smith and Wesson cartridge. The P944 contains a factory main-spring inside the slide assembly. The spring absorbs recoil when the pistol is discharged, forcing the slide back into place while chambering another round. Wolff is a manufacturer of aftermarket accessories for handguns, including combat-grade replacement springs. It's possible to remove your factory spring and replace it with a Wolff spring.

      Pull the slide back until it stops. Press up on the slide stop, located just above the trigger on the left side of the slide. Press the magazine-ejection button on the left side of the frame to remove the magazine.

      Check the chamber to make sure it is empty. If it is not, rack the slide back and forth several times to clear the round.

      Press hard on the stub that extends from the right side of the slide stop. This releases the slide stop on the left. Pull the slide slightly forward until the vertical marks on the left side of the frame are aligned. Pull firmly on the left side of the slide stop until it pulls out about 2 inches and stops. Do not attempt to completely remove the slide stop.

      Pull the slide forward until it catches on the guide rod. Turn the gun upside down, lift up the guide rod and remove it from the barrel lug. Pull out the spring and guide rod.
