I first saw that ad in the Glock Annual and had to laugh. I'd wear any of my S&W's, Sigs, Berettas, Kimbers, Colts, etc on duty, let them submerge, and I wouldn't worry about them functioning again, especially after being detail stripped and cleaned!
That police chief must be an avid firearms authority, knowing that no other manufacturer's handguns could have survived that, huh?
In that same annual, they reprinted a letter they received about a shooting. I remember that two of them were pathetic, but I can only remember what one of them was right now. A father and son were victims of a home invasion, or something like that, and the father fired one shot and both perps ran from the scene. It was "determined" by the police, since they could not find a bullet hole anywhere and nobody turned up at a hospital, that he hit the perp, he later died, and the other perp disposed of the body somewhere where nobody could find it to avoid charges.
If that's the best they could come up with for that magazine, which is basically an advertisement, they NEED to get all the staff back in the advertisement department that jumped ship and went to S&W!
As for the Chief's grammer mistake, I'm not going to comment on that, since I don't know the man, or his reputation. But, I will say that you don't need to be smart in any way to be a Chief. In a town near the one I work in, I know of an officer who was promoted to Chief who graduated LAST in his academy class, and came up with reasons to get out of the daily PT all but THREE DAYS OF THE WHOLE ACADEMY! It used to be the joke "What do you call the person who graduated last in his academy class?.......Officer". Now, it's Chief!
