yes you can buy and install the black grips with no issues

Hi Jon and welcome. Yes, you can swap the grips to the Black Standard Grips. Since Buds does not alter firearms, you would need to get a set of black grips and it only takes a couple of minutes to swap. Cheers and stay safe!

Jon, they can be swapped. If you're asking if Bud's will swap them, that would be no. Bud's does not alter any guns, they are shipped as they come in the box.
Stay safe & have a great day!
