Bottom of the mag works fine, Some of the anniversary 114's were done that way on the mag. Bad thing about the mag though is it can be lost, so I would think the receiver may be better in that respect, but not a lot of real estate to engrave on the receiver so.......
Only gunsmith that engraves that I know of in CO is the one in Denver that used to be on TV...........I know that's no help really, but WTH, I'll throw that out anyway.
