Take it to a gunsmith
Loosen the grip screws.
Many different replacement grips are available for most Smith & Wesson handguns. Take the pistol to a sporting goods shop (be careful of local laws regarding transporting handguns) to find something which matches.
on one side of the grips there should be a screw. take the screw out nad the grips will come off
Remove the magazine and you'll see little spring type clips inside the grips. Just turn them out of the way with something and grips will come off. Ray

You might want to try e-gunparts, if you're looking for original factory grips. Another answer: Try vintagegungrips.com for aftermarket grips. They list 103 grips for $31.00
Give you $20 for them. Thanks, Atson
