I'm putting together a slicked up 870 for my daughter based off a pawnshop Express. Installed a LH trigger plate.

I'd like to mark the shotgun somehow so that someone who picks it up would know it is a LH safety. I do not want to engrave into the receiver.

So far what I've come up with is something like a metal inventory control tag or a small engraved placard placed on the right side of the receiver.

Any other ideas?
