Hand grip for S&W 500

[johnnieg2756]

I bought one of the S&W African series (Leopard) 500's and the small tab on the top of the hand grip is broken off. I can't find out who manufactured these grips for the gun. I wasn't S&W because I have been on the phone with them several times and they aren't sure who manufactured the grips. Any help would be appreciated. Thanks.
