Somewhere on the web(available on the Springfield site) is a 10,000 round test of the 10mm XDm using factory ammunition(Federal Personal defense hydra shock). It went through all the ammo without a single malfunction with three different men shooting it in a tag team type test.
Some have complained that the ammunition used wasn't hot enough to really test the gun. I think ten thousand rounds of factory ammo would certainly be a valid test.
