In other news, I got a reply from John Amidon. I've asked him for clarification, because I want to be sure, but here's the answer I got from him this afternoon:
If it fills in the grip area and thus changing the profile of the factory
produced profile, it would violate 22.2 of appendix D4.
And here's what I sent him to ask the question:
I was wondering if an epoxy treatment filling in the voids of the grip of an XDm would violate section 22.2 of Appendix D4. What I mean is Rich at Canyon Creek Custom has a grip treatment where he puts a gritty epoxy into the gaps of an XDm 5.25 grip. Because it fills in the gaps and changes it from the original configuration, I was worried it would be illegal. I had contemplated doing it, but didn't want to wind up shooting Limited Minor with the gun if it was illegal.
Rich--I guess I'd toss the question to you--do you have correspondence saying otherwise? Or did I ask the question incorrectly?
