Thankfully they put the warning on the bottom of the dust cover on the SR1911s. I think Ruger is the only handgun maker who persists in putting this warning on their handguns...others, like S&W, do include a warning about the gun firing with the magazine removed (if there is no mag disconnect.)

I once inquired about having an Ed Brown 1911 made with nothing whatsoever on it except the serial number, which I could select a custom number. I was told that by law the maker had to be identified on the gun. I can understand requiring a serial number, but why the maker's info? The serial number should give that if needed.
