Here is a link to midway. They are on back order, but they are cheap. Just have to get some panels, locater, and screw. There are some nice panels available on here or fleabay, and they usually come with the screw.
your best bet is to keep searching ebay as they do come up every so often. keep your search broad and look for ruger grips. that's where I found mine and another for a fellow member. you will not be able to find them for 9.00 right now so reset your price limit higher. they are worth it though.
I have some real nice Hogue wood grips, let me know if you have any interest. I could get you some pics. Looking for 40.00 shipped to your door. I believe they retail for 80.00
