Ruger LC380/ LC9

[Gun1]

I recently got a Ruger LC380/LC9. I was surprised to discover that the serial number is actually on the metal insert and not ont he polymer grip, so very similar to the Beretta Apx. I see that there's different colored polymer grips for the Ruger, does anyone know a place to get these polymer grips and just swap the metal insert, since that's the serialized part?

The Grip Frame is a part of the Frame Insert and is not offered for sale
