I am unsure why anyone would want to make a rifle out of a .380, but I would say the Beretta 84, 85 or 86, or the Browning BDA. These are large, all metal guns, with a four-inch barrel to maximize all that velocity. And their more hand-filling grips will make hot loads at least tolerable to shoot. I don't see little plastic-framed pocket pistols holding up for long.
