I don't know about the grips, but the gun with the grips is worth a few bucks, especially if it is unfired. I'd take it to somebody who can accurately give you a value for it because it is worth some pretty good money. Then, the hard part is finding somebody to buy it, if that is what you want to do. If it was me, I'd either sell it or keep it unfired until I wanted to sell it or hand it down to my son. What you have is too valuable to shoot and you want to be sure it is well cared for. You could probably buy three or four new Ruger .22 semi-autos with what you could get for your pistol.
