I have a SP101 that does the same thing if I push hard when using a speed loader. The plunger and spring are staked in position, so it's a factory repair job. So far it hasn't bothered me enough to send it back. Springs can go bad. A few years ago, speedloading my 5" GP100 on the range, I gave the ejector rod a whack with my hand and collapsed the ejector spring. I picked up a used spring on Gun Parts and replaced that one myself.
