I shot my carry gun (M&P 2.0 Compact with a DPP) yesterday in a training class.
The front sight nearly slid out of the dovetail, again, and I had to beat it back in place with a flashlight so it wouldn't fall off and get lost. That happens every hundred rounds or so, even after I've tried staking it in place by peening the dovetail down around it. If you shoot enough you'll see plenty of iron sights fail, too.
If everyone would quit buying cheap dots the whole failure thing wouldn't be an issue.
