Welcome to Bersa Pistol Forum, glad to have you on board from the Lone Star State.
In my own opinion only, having your own initials carved in your pistols grips would not be a problem. However some non PC remarks may cause you a problem and putting notches on them like they did in the wild west years ago may be troublesome to a prosecutor.
I looked at some of the grips sold by Marshals and they had some great looking grips.
