That is a cast piston, if the ring land has pinched then the cast has been yielded enough to VERY possible let sections of piston come loose next to do same thing again. Piston castings are very brittle, they take a lot of punishment but not that type. You can take one and easily crack pieces off by simply striking it with a hammer.
