Noreaster - begs the question, why don't folks just call it "1911-style" or "1911-type?"
I'm with Bob and other old fart colleagues - seems more like a marketing gimmick than anything else. Taking advantage of deconstruction of the English language, in a way. If I quit a job, it might have "affected" the company's operations. But back then, it didn't "impact" the operations. "Impact" was what happened when the howitzer round landed. Don't recall when "impact" became a verb, but I'd guess it wasn't one in the Webster's dictionary of 1955.
