First, I have a family NFA trust and understand the NFA process. I would like to SBR one of my G17s at some point.

How and where (physically) should a Glock frame be engraved?

There are many "firearm engravers" out there, but do you know of any businesses that specifically negrave Glock frames for NFA registration?

Thanks!

I have to punt on this one. AFAIK, you can't engrave on the plastic, and I don't know where else you'd engrave.
