Thank you Josh. My local FFL did it. He charges $125 for compact (like my Glock 43 pictured) and $150 for full size handguns (like my Glock 17). It feels GREAT! No more tape or press on grips that need to be replaced regularly. And no need to worry about sweety hands anymore.
He is an FFL and people from all over the country trust and use him. If you like, PM me and I’ll get you the contact information.
I am not sure you even need an FFL (or their fee) if you are only mailing the polymer lower(?).
