Everybody has a bad day once in a while

....
I think I'd just find a Sharpie and clean it up, but it's your choice.
Now, consider that the Shield is about a $500 gun, give or take. I have a Para CCO, which is more like $900 in the configuration I have, with "Ft. Lauderdale FL" on the frame, out near the muzzle.
No problem with that, except that it looks like it was done with a dot-matrix printer!
(They were made in Canada at the time, but apparently shipped to FL for assembly or some such.)
And, I'm not the only one to report this....
(The CCO is a single stack .45ACP LDA gun, with a 3.5" barrel. Mine's stainless, with night sights. AFAIK, the latter were NOT standard when this gun was made. I wonder if the original owner rejected it because of the printing

.... NIB, btw, otherwise.)
Somewhat seriously, I'd ignore it.... Who knows, it could become a collectable....
(I once bought a brand new 1973 Rambler Ambassador. Decent enough car if you could stand the brand name. On the way to the office, the headlight switch knob came off in my hand. Then, one of my buddies decided he had to play with the reclining seats. Turns out that there were three ways to install the seat back, and two were wrong. Fifteen minute fix, not counting driving back to the dealer's with the driver's seatback held up by the seatbelt.... My third and last Rambler, btw. Not really all that bad, and I'd had good luck with the prior two, but $200 more would have bought me the equivalent Ford and a lot fewer problems. The next car was a Ford

.)
It is, IMHO, pretty stupid to put that warning on the slide, but lawyers seem to run the world. Along with Harvard MBA's. Neither species having the slightest idea of what the marketplace looks like, and both planning on being someplace else when it's noticed....
