Numrich, Sarco, Bob's Gun Parts--all online in the US. Ehrenreich in Germany, but they do not export to US. Otherwise, keep your eyes peeled for auctions on eBay and Gunbroker.com. A periodic Google search may also give results. I have some factory original checkered plastic grips that I'd sell, if you need them. ithacaartist@gmail.com
