Anyone know what became of his Victory Model .38, from PT-109?

He supposedly chose it over a Colt.45 auto because he wanted a gun made in his home state.

After his PT boat was sunk, he allegedly wore this .38 on a lanyard as he swam to an island seeking help for his crew.

When George Bush's Avenger was shot down and his gunner killed, Bush gave his .38 to an officer on the sub that rescued him. It's still in the possession of that man's family, last I heard. Barbara Bush reportedly wouldn't allow George to keep a handgun, and his interest in them seems to have been low.

I think the Bushes mainly hunted birds with shotguns. Haven't read anything else on guns they may have.
