Hello all. New to the forum but I ran into an issue with an EAA Witness..

In the middle of a RIA 9mm 1911 rebuild I decided to try Alumihyde 2 from Brownells and change the frame of my 9mm/22conv from black to Coyote Tan. Just to be different. How many black guns do you see every day?

I did a detail strip and went over the frame a few times with 400 grit wet or dry and almost took the S/N off. It's barely in the steel.

I guess I'm going to have to get a stamp set and stamp the number into the frame.:cuss: Unless someone has another idea?:banghead:

I don't know how to upload pics yet but they are here

Thanks for any input!

I would hire an engraver to "pick up" the serial number. IMHO, re-stamping could be construed as "altering" the serial number.

There's a very fine line when dealing with this sort of thing.

Thanks U.R. I thought about that but I do have the recipt and the box it came in with the SN on it. If there was ever an issue I was planning on playing dumb. I rule at playing dumb. I don't even have to play.

Good to know, I always thought the S/N looked pretty shallow on my witness. Let us see the refinish when you are done. I sure would not mind changing mine a bit.

I don't think "playing dumb" is much of a defense when dealing with the BATF.

$40 bucks to an engraver today, is cheaper than any lawyer tomorrow.

Whats the 1911 have to do with the witness frame?

The serial number on my "Mossad" Tanfoglio 9MM in the "wonder finish" is very "shallow" and it almost looks like a gun that's been refinished, but it hasn't been.

The reason serial numbers can't be stamped over is the same reason they must be stamped or engraved in the first place; Even if the serial # is ground off the metal beneath it can be etched to show what was once there (stamping and even engraving compress the metal beneath numbers).

Re-stamping(unlikely you have the same stamps as the factory), messes with this potential and that is why, it is illegal.

That is the condensed explanation I got from the BATF 15 years ago.

IMHO, If you cover the serial # with paint or it's not a huge deal unless the AHJ demands you scrape it off so the serial # can be read.

The BATF enforce gun laws with a vengance, ask any dealer or gunsmith that has ever been audited.

I decided I didn't want to stamp it because that may be altering it. I checked with an engraver but it would be a 1.5 or 2 hour rd trip to drop and then another to pick up.

I think I'll just try to use a pick and clean up the S/N between coats and if someone official ever asks I'll scrape the coating off.

Thanks for the input.:) and I'll put up pics when I get done.
