“Japan didn’t go after our mainland because they heard the citizens were armed.”
Supposedly bogus per wikipedia.
“
You cannot invade the mainland United States. There would be a rifle behind every blade of grass. It has been declared this attribution is “unsubstantiated and almost certainly bogus, even though it has been repeated thousands of times in various Internet postings. There is no record of the commander in chief of Japans wartime fleet ever saying it.”, according to Brooks Jackson in “Misquoting Yamamoto” at Factcheck.org (11 May 2009)”

ps. hollow points were/are used so that the bullet does not over penetrate and hit somethign beyond what you are shooting at. They do fragment and make a mess when hitting a living creature. (I think Reagan was shot with .22 hollow points)
